cover Initial multi-omap support for omap4

Hi all,

These patches allow compiling in also omap4 into the multi-omap configuration. As I don't yet have omap4, I've only boot tested these on omap2 and omap3.

Somebody with an omap4 board please boot test these with the omap3_defconfig and see what happens.. You might want to enable DEBUG_LL and EARLY_PRINTK with earlyprintk on the cmdline too.

Regards,

Tony

PATCH 4/9 omap2/3/4: Clean up entry-macro.s for adding support for omap4 multiboot

In reply to Tony Lindgren

Move defines around and set up handlers based on MULTI_OMAP2.

Note that this will only allow compiling in omap4 with omap2 and omap3. It will not yet make omap4 boot with multi-omap.

PATCH 7/9 omap: Fix gpio.c for multi-omap for omap4

In reply to Tony Lindgren

Set up METHOD_GPIO_44XX instead of trying to use the METHOD_GPIO_24XX.

PATCH 9/9 omap2/3/4: Add omap4 into omap3_defconfnig

In reply to Tony Lindgren

Add omap4 into omap3_defconfig. Note that this does not yet boot on omap4, but boots on omap2 and omap3.

Also note that CONFIG_SMP does not currently work on uniprocessor ARMs.

Subject: [PATCH 0/9] Initial multi-omap support for omap4

Hi all,

Quoted 7 lines

These patches allow compiling in also omap4 into the multi-omap configuration. As I don't yet have omap4, I've only boot tested these on omap2 and omap3.

Somebody with an omap4 board please boot test these with the omap3_defconfig and see what happens.. You might want to enable DEBUG_LL and EARLY_PRINTK with earlyprintk on the cmdline too.

Looks like this series have some dependent series because it doesn't apply on mainline.

So I tested this directly on linux-omap "multi-omap4" branch. It boots sufficiently but doesn't proceed after "brd_init". Didn't get much time to debug so attached log

Regards,
Santosh

Sorry, forgot to mention that these are against the earlier multi-omap patches. Basically stuff that's now queued for the merge window in the omap-for-linus branch.

Thanks for testing. Yeah these same are in the multi-omap4 branch also.

Stand alone omap_4430sdp_defconfig also didn't fully boot on the linux-omap "multi-omap4". The log below shows that the serial platform data isn't configured correctly.

Below patch to fix the boot for omap_4430sdp_defconfig. Small typo really.

Heh OK :) Sounds like at this point it makes sense to merge that into the original patch redo omap-for-linus partially.

Can I also add your Acked-by for these patches then?

[*] Reset unused clocks during boot

Sounds like omap4 has some clocks left on from the bootloader that it should clk_get and clk_enable during init. That should be easy to track if you boot with "debug" in your cmdline and take a look at the list of unused clocks that are shut down with late_initcall.

Cool, thanks, good to hear!

Now the only omap2/3/4 that's not booting with omap3_defconfig is 2430 because of the different clock offsets compare dot 2420. That should get fixed eventually though.

Tony

I know it hangs when it tries to cut down UART3 ( console) clock. The clock support got just recently merged and drivers are not yet migrated so, need to still depend on bootloader. The work is ongoing and soon the patches will be pushed. Few drivers are planned to be handled in hwmod way so we were holding these patches.
