Updating SPEAr Support
Subsystems (4)
v5 cover Updating SPEAr Support
Following set of patches:
- updates SPEAr3xx, 6xx support
- Adds support for SPEAr13xx
- Removes Multiple defconfigs per machine family
Changes since V4:
- Following patch is added
SPEAr: Defining IOMEM(x) and updating declaration of MISC_BASE
- variables referring to register now have type void __iomem *, instead of u32 *
- using linux/gpio.h instead of mach/gpio.h in *evb files.
- return value of clk_get(), and clk_get_sys are checked using IS_ERR().
- unused routines removed from headsmp.S
- spear13*_pcie_port_is_host routines are declared static
- platsmp.c updated according to review comments.
- Added clk_round_rate routine() and used it to check possible rate before calling cpufreq_notify_transition in cpufreq.c
- & removed before function names, while passing function pointer to other routines.
Changes since V3:
- SPEAr13xx: gic init, smp and hotplug code updated w.r.t. latest linus/master
- Appending UL to VMALLOC_END Macros
- readl & writle _relaxed used instread _raw in uncompress.h
- infinite loop removed from arch_reset() in mach-spear13xx/include/mach/system.h
- patch: ST-SPEAr13xx-Modified-static-mappings is broken into two patches. Now, static mapping for SPEAr1310 RAS will be present only on 1310 machine.
- Updated commit message of: SPEAr Power Management: Added the support for Standby mode
- Default ssp freq changed to 25MHz.
- patch: ST-SPEAr-13xx-Adding-support-for-SPEAr1310 is splitted into two patches. Separate patch for 320 CAN is added.
- Wrapper routine spi_init() in spear*evb.c files is removed.
- routine i2c_register_board_devices() is renamed to i2c_register_default_devices() in arch/arm/plat-spear/i2c_eval_board.c file
- Following patches are removed from this patchset, they will be added separately:
ST-SPEAr-FSMC-Flexible-Static-Memory-Controller-NOR-.patch
- Following patches are already present in linus-next or already Acked, so they are also removed from this patchset:
Newly-erased-page-read-workaround.patch
Changes since V2:
- Following patches are removed from this patchset, as they are still under review:
ST SPEAr: PCIE gadget suppport
ST SPEAr13xx: Adding machine support for pci gadget
ST SPEAr: Add smi driver for serial NOR flash
ST SPEAr: Adding support for serial nor flash in all spear platforms
- Following patches are already present in linus-next, so they are also removed from this patchset:
mtd/fsmc.h: including linux/io.h for definition of readl
Keyboard: Adding support for spear-keyboard
USB host: Adding USB ehci & ohci support for spear platform
- spear-keyboard machine support is updated according to updations in driver (driver is already in linus-next)
- rtc driver is updated and ioctl routine is removed.
Changes since V1:
- sev definitions moved to system.h and removed from spear and omap archs
- bug fix added in system controller file sp810.h
- Review Comments incorporated
- Driver and machine support are divided into separate patches
- Nand Driver is removed from patch list as it is already floated by Linus Walleij.
- Few later patches of SPEAr13xx Patches are merged with initial patches of SPEAr13xx
- Smaller Defconfigs are used instead of large.
- Clock renaming & minor corrections are moved to clock specific patches from peripheral machine support patches.
- Removed Commented code related to SPI
- [PATCH] Incrementing the ecc_pos array to contain 128 char - is removed from list
- Board specific code is moved to *evb.c files from machine files for EMI NOR
- replaced readl with __raw_readl in uncompress.h in plat-spear/include/plat/

From: Shiraz Hashim <[email protected]>
Before resetting system from system controller, switching to slow mode is required.
This comment could do with some expansion about why it is required. Eg, this comment could become:
"sp810: switch to slow mode before reset
In sysctl_soft_reset(), switch to slow mode before resetting the system via the system controller. This is required by the SPEAr reference manual."

PATCH v5 5/63 ST SPEAr: Making clock functions more generic
In reply to Viresh KumarModifications include:
- Adding dummy clk_set_rate function. Required for compilation of few drivers
- Making function present in plat-spear/clock.c more generic over all platforms
- Added div_factor filed in struct clk for clks with .recalc = follow_parent
- changing type of register pointers to void __iomem *

As I said in the patch system, I think this should be a preparatory patch before adding spear13xx support. So I've committed this patch without the spear13xx changes. When I commit the spear13xx changes I'll fold them into that patch.

This looks to me like another bug fix, and I'm treating it as such. It should be submitted separately from this patch set along with other bug fixes, and clearly labelled as such.
I've also changed the comments on this patch to:
"SPEAr: Correct SOC config base address for spear320
SPEAR320_SOC_CONFIG_BASE was wrong, causing the wrong registers to be accessed."

PATCH v5 29/63 ST SPEAr: Changing resource size of amba devices to SZ_4K
Quoted 3 lines · Russell King - ARM Linux
This is another patch which should be reorganized - move the CLCD bits into the CLCD patch and arrange for it to be applied early on in the series.
Doesn't we need to drop CLCD patch for now?

PATCH v5 30/63 ST SPEAr: Replacing SIZE macro's with actual required size
In reply to Viresh KumarFrom: Shiraz Hashim <[email protected]>
In arch specific files SIZE macro's were defined which were used for creating memory/io mappings for sepecific devices. These macro's are coming straight from h/w user manual and are much greated than required sizes. Replacing these macros by actual required size.

Same comments as the other patch changing to SZ_* macros. Where possible fold these changes into the patch(es) which add the original definitions rather than having patches which add stuff and then separate patches which rework those patches.
Could you do that and provide reworked patches please? I'll publish the branch I've merged stuff onto thus far (but note that it's 'unstable'), but note that it won't contain the bits I've merged into the 'fixes' branch.

Russell,
I have taken care of above two steps, but i have some doubt.
I have made changes at few places:
- EMI driver: Changes according to your review comments.
- Removed CLCD patch, as you mentioned that earlier.
- fixed PLGPIO & EMI patch issue resolved, code has been put to individual patches and patch 57 removed completely.
- PATCH 29 & 30 are placed at the top and changes made other individual patches
So sending only first 10 patches looks a bit insufficient to me? Would be better to send all of them (leaving what you have already applied), so that they apply cleanly at your end.

I don't know, and I'm getting to the point of giving up with this SPEAr stuff. It's more trouble and time consuming than it's worth because of the size of the patch set. It's just *too* large to properly deal with.

Please don't do that now. I agree that it was too big to get reviewed and get added.
I will make it sure, that it doesn't happen again from our side. But now lots of effort
has already been put on it, by everybody in reviewing and preparing them.
Let me check, might be only few patches are required to be resent and others will
automatically apply over them.

PATCH v5 35/63 ST SPEAr: Adding support for DDR in clock framework
In reply to Viresh KumarChanging rate of clk, which is ancestor of DDR requires to put DDR in refresh mode before changing parents rate. For this DDR support is added in clock framework. Now at boot time all ancestors of DDR is marked specially and changing their rate must be first acked by ddr (i.e. ddr will run on that clock). This patch adds support for this.

I don't see why this has to be code rather than in the platform specific files as static initializers. Also, you seem to be passing stuff like 'EMI_FLASH_WIDTH32' in for 'width', which seems very odd as this is the byte width. I don't see why you need #defined constants for this.
It's waiting someone who doesn't realise that it has a proper meaning to change it to an enum or something like that.
If you think the physmap flash API is lacking some definitions for this, please talk to the MTD people.

Ok, but I don't see why this should be in the EMI code. Surely this should be along side the nor device, and called 'nor_init_board_info' or something similar?

Open Points:
-> Suspend to RAM support needs to be added. -> SPEAr13xx: The power domains need to be added. -> For SPEAr13xx: PLL-4 has not been switch off while moving into sleep. There is some problem in getting the pll back to on.

readl also calls outer cache maintainance operations which are not available during Linux uncompression. This patch replaces readl, writel with
readl_relaxedandwritel_relaxed.
Shouldn't this be near the start of the series?
Also, would:
"SPEAr: replace readl, writel with relaxed versions in uncompress.h
readl() and writel() calls the outer cache maintainance operations which are not available during Linux uncompression. This patch replaces readl() and writel() with readl_relaxed() and writel_relaxed() to avoid the link time errors."
be a better patch description?

The new static io mappings map regions in 0xE...,.... space to 0xF...,.... and those in space 0x6...,.... to 0xE...,.... range. This is done to accomodate regions of RAS configuration registers to be used by clock frameowrk and possibly others.

PATCH v5 46/63 SPEAr : Pad multiplexing handling modified
In reply to Viresh KumarFrom: Vipin Kumar <[email protected]>
Until now, the platform code assumed 1 32 bit register to be used for pad multiplexing. This assumption is not true for SPEAr13xx devices, so the generic implementation of pad multiplexing adopts a new concepts of multiple multiplexing registers.

PATCH v5 54/63 SPEAr3xx: Rework KConfig to allow all boards to be compiled in
In reply to Viresh KumarFrom: Ryan Mallon <[email protected]>
Now that all three SPEAr3xx platforms can be built into one kernel, rework KConfig to allow this. Move everything into one KConfig file while we are here.
