cover arm: socfpga: Usability fixes

This entire series is the second stab at making SoCFPGA usable with mainline U-Boot again. There are much fewer bits missing than in the last series, more cleanup happened and bugs were fixed. This allows me to use mainline U-Boot on my SoCFPGA systems.

The big missing part is the SPL generation, which still needs a lot of additional work. We also miss the Cadence QSPI controller driver.

This set contains patches for a few subsystems, which are utilized by the SoCFPGA, but the most part is the SoCFPGA chip support. This series now contains cleanup for the mayhem in drivers/fpga/altera.c code, which was terrible, but is now much better.

Fix remaining cache alignment issues in the DWC Ethernet driver. Please note that the cache handling in the driver is making the code hideous and thus the next patch cleans that up. In order to make this change reviewable though, the cleanup is split from it.

Current flush_dcache_range will clean & invalidate the whole cache line which contain the address specified by start and end. Hence I believe the alignment is not needed. Wonder the existing code got issue?

Current flush_dcache_range will clean & invalidate the whole cache line which contain the address specified by start and end. Hence I believe the alignment is not needed. Wonder the existing code got issue?

Don't be mistaken, please see drivers/net/designware.h :
sizeof(desc_p->txrx_status) == sizeof(u32) == 4

Thus the flush is called like so:
flush_dcache_range(<address of start of DMA descriptor>,

                   <address of start of DMA descriptor> + 4);

On ARM, the cache ops have to be aligned to cacheline length, so the above code will indeed have issues. Thus the alignment.

The subsequent patch just converts this whole mess to flushing the entire descriptor , which is much more sane approach to take.

Best regards,
Marek Vasut

PATCH 4/51 net: dwc: Make the cache handling less cryptic

In reply to Marek Vasut

Add a few new variables to make the cache handling less cryptic. Add a variable for DMA and DATA descriptor start and end, so the correctness of the code is easier to inspect.

PATCH 4/51 net: dwc: Make the cache handling less cryptic

Quoted 109 lines · marex at denx.de

Add a few new variables to make the cache handling less cryptic. Add a variable for DMA and DATA descriptor start and end, so the correctness of the code is easier to inspect.

PATCH 6/51 mmc: dw_mmc: Fix cache alignment issue

In reply to Marek Vasut

The DMA descriptors used by the DW MMC block must be aligned to cacheline size, otherwise we are unable to properly flush/inval cache over them and we get data corruption.

The reason I chose this approach of expanding the structure is because the driver allocates the descriptors in bulk. This approach does waste space by inserting slop inbetween the descriptors, but it makes access to the descriptors easy as the compiler does know the real size of the structure. It also makes cache operations easy, since the size of the structure is cache aligned and the structure start address is as well.

Wonder the ALLOC_CACHE_ALIGN_BUFFER within function dwmci_send_cmd at drivers/mmc/dw_mmc.c already take care this?

This won't help, since you want to do cache ops only on one descriptor at a time. The ALLOC_CACHE_ALIGN_BUFFER will allocate an array of the descriptors with aligned start address and end address, but won't insert the necessary padding inbetween the elements so that each descriptor starts at the begining of a cacheline. So you can do:

flush_dcache_range((u32)desc, (u32)desc + sizeof(*desc));

where $desc is a pointer to the n-th element in the array of descriptors.

I explained in the commit message why I didn't go for a scheme where the descriptors would be tightly packed one after the other -- it is possible to do it, but the already obscure cache handling mechanism would be even more complex that way and thus more bug-prone.

Best regards,
Marek Vasut

PATCH 7/51 tools: socfpga: Add socfpga preloader signing to mkimage

In reply to Marek Vasut

From: Charles Manning <[email protected]>

Like many platforms, the Altera socfpga platform requires that the preloader be "signed" in a certain way or the built-in boot ROM will not boot the code.

This change automatically creates an appropriately signed preloader from an SPL image.

The signed image includes a CRC which must, of course, be generated with a CRC generator that the SoCFPGA boot ROM agrees with otherwise the boot ROM will reject the image.

Unfortunately the CRC used in this boot ROM is not the same as the Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a CRC but is more correctly described as a checksum.

Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

PATCH 7/51 tools: socfpga: Add socfpga preloader signing to mkimage

Hi Charles,

Quoted 128 lines · marex at denx.de

From: Charles Manning <[email protected]>

Like many platforms, the Altera socfpga platform requires that the preloader be "signed" in a certain way or the built-in boot ROM will not boot the code.

This change automatically creates an appropriately signed preloader from an SPL image.

The signed image includes a CRC which must, of course, be generated with a CRC generator that the SoCFPGA boot ROM agrees with otherwise the boot ROM will reject the image.

Unfortunately the CRC used in this boot ROM is not the same as the Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a CRC but is more correctly described as a checksum.

Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

misc_init_r happens at some time after U-Boot entry. Afraid the watchdog might trigger prior its disabled. Suggest to call socfpga_watchdog_reset earlier.

arch_cpu_init() might be a good idea, thanks.

PATCH 13/51 arm: socfpga: clock: Drop nonsense inlining from clock manager code

In reply to Marek Vasut

The inlining is done by GCC when needed, there is no need to do it explicitly. Furthermore, the inline keyword does not force-inline the code, but is only a hint for the compiler. Scrub this hint.

PATCH v2 15/51 arm: socfpga: clock: Add code to read clock configuration

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Add the entire bulk of code to read out clock configuration from the SoCFPGA CPU registers. This is important for MMC, QSPI and UART drivers as otherwise they cannot determine the frequency of their upstream clock.

PATCH 18/51 arm: socfpga: clock: Sync with reference code

In reply to Marek Vasut

Add the missing pieces from the reference clock code from Altera. This puts the code on par with the Altera U-Boot fork for all but the SDRAM self-refresh bits, which are not part of this patch.

PATCH 19/51 arm: socfpga: mmc: Pick the clock from clock manager

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Make the SoCFPGA MMC stub pick clock via the clock manager frequency accessors instead of hard-coding the frequency.

Also fix calloc() misuse.

PATCH 20/51 arm: socfpga: timer: Pull the timer reload value from config file

In reply to Marek Vasut

The timer reload value is a property of the timer hardware and there is no reason for this to be configurable. Place this into the timer driver just like on the other hardware.

PATCH 21/51 arm: socfpga: reset: Add EMAC reset functions

In reply to Marek Vasut

Add functions to reset the EMAC ethernet blocks. We cannot handle two EMAC ethernet blocks yet, therefore the ifdefs. Once there is hardware using both EMAC blocks, this ifdef will have to go.

PATCH 22/51 arm: socfpga: misc: Add proper ethernet initialization

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Add function to initialize the EMAC blocks upon board startup. The preprocessor guards against building on SoCFPGA-VT and against SPL build are not needed as those are handled implicitly via both SPL framework and the socfpga_cyclone5.h config file, which will not define CONFIG_DESIGNWARE_ETH if building for SoCFPGA-VT.

We cannot handle two EMAC ethernet blocks yet, therefore the ifdefs. Once there is hardware using both EMAC blocks, this ifdef will have to go.

The patch does not address this issue, this is addressed by one of the patches further down the pipe (but it is addressed). I tried to keep these patches somewhat separated to keep the changes reasonably contained, but the file was a mess. The best suggestion I can give you is to use checkpatch -f on the resulting altera.c file ; there are still a few warnings, but it's much better than it was.

Best regards,
Marek Vasut

PATCH 28/51 fpga: altera: Clean up altera_validate function

In reply to Marek Vasut

Boldly go, where no programmer has gone before and just clean up the indentation mayhem. No functional change.

I'm sure it will, but this was resolved somewhere down the patch stack. The final result doesn't have this warning.

PATCH v2 34/51 arm: socfpga: fpga: Add SoCFPGA FPGA programming interface

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Add code necessary to program the FPGA part of SoCFPGA from U-Boot with an RBF blob. This patch also integrates the code into the FPGA driver framework in U-Boot so it can be used via the 'fpga' command.

PATCH 35/51 arm: socfpga: reset: Add function to reset FPGA bridges

In reply to Marek Vasut

Add function to enable and disable FPGA bridges. This code is used by the FPGA manager to disable the bridges before programming the FPGA and will later be also used by the initialization code for the chip to put the chip into well defined state during startup.

PATCH 48/51 arm: socfpga: Add command to control HPS-FPGA bridges

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Add command to enable and disable the bridges between HPS and FPGA.

This patch does have a checkpatch issue with the assembler portion, checkpatch correctly complains that there should be no whitespace before quoted newline. I do not agree that fixing this specific checkpatch issue will improve the readability, thus this one is not addressed.

PATCH 49/51 arm: socfpga: Clean up SoCFPGA configuration

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Reorganize and cleanup the configuration file for SoCFPGA. There is no functional change after this cleanup. This was necessary, since the file was a wild mess and it was impossible to make sense of it's content, let alone change something without breaking some other thing. This patch puts the contents on par with regular U-Boot standards.

Also remove unused preprocessor symbols CONFIG_SINGLE_BOOTOADER and CONFIG_USE_IRQ, which is undefined by default. Finally, do logical reordering of the defines in the file so it's much more readable. The reordering was also necessary for the splitting as the initial one was messy.

PATCH 50/51 arm: socfpga: Split SoCFPGA configuration

In reply to Marek Vasut

From: Pavel Machek <[email protected]>

Split the SoCFPGA configuration into SoC-specific part which is common for all boards (socfpga_cyclone5_common.h) and a board specific part. There is currently only one board, which is the generic SoCFPGA board (socfpga_cyclone5.h), but there are more to come.

This is necessary due to various features of the boards, which unfortunatelly cannot be autodetected.

PATCH 50/51 arm: socfpga: Split SoCFPGA configuration

Quoted 18 lines · Marek Vasut

From: Pavel Machek <[email protected]>

Split the SoCFPGA configuration into SoC-specific part which is common for all boards (socfpga_cyclone5_common.h) and a board specific part. There is currently only one board, which is the generic SoCFPGA board (socfpga_cyclone5.h), but there are more to come.

This is necessary due to various features of the boards, which unfortunatelly cannot be autodetected.

Thanks for taking a stab at this, but I think it makes more sense to have socfpga_commoh.h and socfpga_cyclone5.h. The _common file can have most of the common settings for u-boot, while _cyclone5 will have the base addresses for all the various IP blocks. Then once everything is done for Cyclone5, we can add support for the Arria5 SOC by just adding socfpga_arria5.h.

socfpga_common.h sounds like a good name.

But I wonder if socfpga_cyclone5.h should be named socfpga_cyclone5_socdk.h ?

To be consistent with Linux DTB name even ? Might be a good idea, but not for this patch . This patch doesn't introduce any "functional" change either for the build or for the result.

cover arm: socfpga: Usability fixes

In reply to Marek Vasut
Quoted 5 lines · Marek Vasut

This entire series is the second stab at making SoCFPGA usable with mainline U-Boot again. There are much fewer bits missing than in the last series, more cleanup happened and bugs were fixed. This allows me to use mainline U-Boot on my SoCFPGA systems.

Quoted 7 lines

The big missing part is the SPL generation, which still needs a lot of additional work. We also miss the Cadence QSPI controller driver.

This set contains patches for a few subsystems, which are utilized by the SoCFPGA, but the most part is the SoCFPGA chip support. This series now contains cleanup for the mayhem in drivers/fpga/altera.c code, which was terrible, but is now much better.

Thanks Marek!

I have tested your latest patchset on the EBV SoCrates board. And it works really good. Once this is all available in mainline I'll send a patch to add the SoCrates and a new custom SoCFPGA board support to the list.

For now, please add my tested-by to the patchset:

Thanks,
Stefan

Thanks Marek, I tested this series of patches and here are the outcome I have.

SDMMC - Working as I can read and write to SDMMC
Boot - Working as I can boot till Linux
Ethernet - Seems not working for me.

I will help to look into those features which are not working for me. But this series of patches serves as a good start.

I suspect that's because the ethernet support in the originally upstreamed SoCFPGA code never worked on the SoCDK in the first place. I think the SoCDK uses EMAC1, but the mainline code uses EMAC0 for whatever reason.

Edit include/configs/socfpga_cyclone5.h and change:
-#define CONFIG_EMAC_BASE SOCFPGA_EMAC0_ADDRESS
+#define CONFIG_EMAC_BASE SOCFPGA_EMAC1_ADDRESS

Does this work ?

I zap'd the "run bridge_enable_handoff" thing and replaced it with "bridge enable" command. Could that be the case ?

Please let me know if some of the above help first. The network part should and if it does, then I will add a patch. The FPGA part should as well

Also, I separated the patches into smaller groups, which I will resubmit one more time, but you can find a merge of all of them at [1], so you don't have to apply them by hand. Please be advised, that those branches will be replaced with a never ones, that's why there's the timestamp at the end of the name (so check the repository if there is no new topic/arm/socfpga-yyyymmdd). Also, I will likely garbage collect the old ones at some point.
