Hi all,
These patches enable multiplatform support for omap2plus.
To build and boot it against the current mainline kernel
you need the following:
[PATCH 1/2] ARM: l2x0: Only set .set_debug on PL310 r3p0 and earlier
[PATCH 2/2] ARM: disable errata work-arounds which access secure registers
[GIT PULL 1/2] omap fixes for v3.8 merge window
[GIT PULL 2/2] omap cleanup for v3.8 merge window
[GIT PULL] two trivial omap build error fixes for v3.8 merge window
cpts: Fix build error caused by include of plat/clock.h
Regards,
Tony

We need to make sure that multiplatform kernels don't
run omap initcalls when booted on other SoCs.
Do this by adding wrapper macros for the initcalls that
return early if soc_is_omap() test fails. This allows
us to easily change the defines later if we have SoC
specific init sections available.

This way the initcalls don't run on other SoCs on multiplatform
kernels. Otherwise we'll get something like this when booting
on vexpress:
omap_hwmod: _ensure_mpu_hwmod_is_setup: MPU initiator hwmod mpu not yet registered
...
WARNING: at arch/arm/mach-omap2/pm.c:82 _init_omap_device+0x74/0x94()
_init_omap_device: could not find omap_hwmod for mpu
...
omap-dma-engine omap-dma-engine: OMAP DMA engine driver

* [PATCH 2/8] ARM: OMAP2+: Use omap initcalls
@ 2012-12-19 19:26 ` Tony Lindgren

To: linux-arm-kernel
This way the initcalls don't run on other SoCs on multiplatform
kernels. Otherwise we'll get something like this when booting
on vexpress:
omap_hwmod: _ensure_mpu_hwmod_is_setup: MPU initiator hwmod mpu not yet registered
...
WARNING: at arch/arm/mach-omap2/pm.c:82 _init_omap_device+0x74/0x94()
_init_omap_device: could not find omap_hwmod for mpu
...
omap-dma-engine omap-dma-engine: OMAP DMA engine driver
...

* [PATCH 3/8] ARM: OMAP: Fix i2c cmdline initcall for multiplatform

To: linux-arm-kernel; +Cc: linux-omap
We only want this initcall to run when the kernel is
booted on omap SoCs. Fix the issue by initializing the
the initcall from separately for omap1 and omap2+.
This fixes the issue for omap2+ multiplatform configs
as we are using omap_subsys_initcall there.

* [PATCH 6/8] ARM: OMAP2+: Disable code that currently does not work with multiplaform

We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.
The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:
1. Some drivers are using custom omap_dm_timer calls
There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.
2. Hardware OMAP4_ERRATA_I688 needs to be fixed up
This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.
3. Legacy header needed for omap-sham.c
Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.

Flip on multiplatform support for omap2+.
No changes to omap2plus_defconfig needed, but please note
that you may need to update your custom config files to
make sure you have:
CONFIG_ARCH_MULTIPLATFORM=y
CONFIG_ARCH_MULTI_V7=y
CONFIG_ARCH_OMAP2PLUS=y
And may need CONFIG_ARCH_MULTI_V6=y if booting omap2 boards.

Flip on multiplatform support for omap2+.
No changes to omap2plus_defconfig needed, but please note
that you may need to update your custom config files to
make sure you have:
CONFIG_ARCH_MULTIPLATFORM=y
CONFIG_ARCH_MULTI_V7=y
CONFIG_ARCH_OMAP2PLUS=y
And may need CONFIG_ARCH_MULTI_V6=y if booting omap2 boards.

With multiplatform support enabled we are now always
building in vexpress. Let's enable few drivers also as
this allows us to boot omap2plus zImage in qemu for
testing multiplaform related changes.

Few notes on booting this as at least Lokesh already hit the mkimage
issue like I did earlier.
To boot this you also need to run mkimage manually on the zImage:
$ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \
-n "Linux" -d zImage-omap2plus uImage-omap2plus
And to boot the vexpress on qemu something like this should do:
$ qemu-system-arm -machine vexpress-a9 -m 1024 -net nic -net user -serial stdio \
-append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait" \
-kernel zImage-omap2plus -initrd initrd.img -sd rootfs.img
I had to build the Linaro qemu to get it to boot, for some reason the
version of qemu in debian unstable did not boot vexpress for me.
Regards,
Tony

I'm trying this on my IGEP v2 board (using Javier's patches for DT).
I've applied these series on top of your branch
"omap-for-v3.8/fixes-for-merge-window-part2".
However, I'm finding some conflicts (fb.c appears in plat-omap,
some missing headers, etc.)
Could you suggest a better branch to base the series?
Thanks!

Maybe use Olof's lates pull request for fixes from LAKML +
ARM: l2x0: Only set .set_debug on PL310 r3p0 and earlier +
ARM: disable errata work-arounds which access secure registers
and these patches?
Or just wait for -rc1 and then I'll push out a branch.

Can you try it on current mainline.
It applies without any conflicts..

FYI, I've successfully booted my IGEPv2 board using:
* arm-soc/for-next
* igep DT patches
* this multiplatform series
* the two patches mentioned above
With this series CONFIG_MACH_IGEP0020 is not needed,
just CONFIG_MACH_OMAP_GENERIC is selected.
So I guess this means, for igep v2,

Ah right, sorry this series also needs the omap branch
omap-for-v3.8/cleanup-for-merge-window that's now in
arm-soc/for-next. Specifically it's the "ARM: OMAP: Split
fb.c to remove last remaining cpu_is_omap usage" patch.

These are no longer needed, we now have to select the
debug_ll port manually. The new multiplatform version of the
debug_ll code is in arch/arm/include/debug/omap2plus.S.

* [PATCH 9/8] ARM: OMAP2+: Remove now obsolete uncompress.h and debug-macro.S

These are no longer needed, we now have to select the
debug_ll port manually. The new multiplatform version of the
debug_ll code is in arch/arm/include/debug/omap2plus.S.

Hi all,
Looks like we need to also disable mailbox to avoid dependencies to
the mailbox series as it's being moved to live under drivers.
And we need to disable omap3isp as it tries to use the now private
include <plat/*.h> headers.
Updated patch below.

Subject: [PATCH] ARM: OMAP2+: Disable code that currently does not work with multiplaform
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.
The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:
1. Some drivers are using custom omap_dm_timer calls
There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.
2. Hardware OMAP4_ERRATA_I688 needs to be fixed up
This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.
3. Legacy header needed for omap-sham.c
Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.
4. Mailbox is waiting to get moved to drivers
Disable it for now to avoid adding a dependency to the
mailbox patches.
5. Camera omap3isp needs to be disabled
The include <plat/*.h> files won't be available to drivers
after multiplatform support is enabled.

* [PATCH 6/8] ARM: OMAP2+: Disable code that currently does not work with multiplaform

Hi all,
Looks like we need to also disable mailbox to avoid dependencies to
the mailbox series as it's being moved to live under drivers.
And we need to disable omap3isp as it tries to use the now private
include <plat/*.h> headers.
Updated patch below.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.
The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:
1. Some drivers are using custom omap_dm_timer calls
There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.
2. Hardware OMAP4_ERRATA_I688 needs to be fixed up
This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.
3. Legacy header needed for omap-sham.c
Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.
4. Mailbox is waiting to get moved to drivers
Disable it for now to avoid adding a dependency to the
mailbox patches.
5. Camera omap3isp needs to be disabled
The include <plat/*.h> files won't be available to drivers
after multiplatform support is enabled.

I've posted a patch to the linux-media mailing list to remove plat/*.h headers
that are not present anymore in v3.8. It will be pushed to v3.8, as this
breaks compilation of the driver.
The driver still includes the plat/cpu.h header that can be removed as well.
I've just posted a patch that remove the header and will push it to v3.9. The
OMAP3 ISP part of this patch can thus be dropped.

Great, thanks for doing that.

OK. I suggest you merge the plat/cpu.h during the -rc cycle as well.
With v3.8-rc2 plat/cpu.h no longer contains anything for omap2+, and
we could make it now to do #error for omap2+ if the current users
are fixed.
Will drop the omap3isp part from this patch as you suggested though.

Great, thanks for doing that.

OK. I suggest you merge the plat/cpu.h during the -rc cycle as well.
With v3.8-rc2 plat/cpu.h no longer contains anything for omap2+, and
we could make it now to do #error for omap2+ if the current users
are fixed.
Will drop the omap3isp part from this patch as you suggested though.

If Mauro is fine with the patch going to v3.8-rc I have no issue with that. Is
this patch targetted at v3.8 or v3.9 ?

Well ideally ASAP to prevent new drivers including plat/cpu.h as otherwise
build breakage will occur when we flip on the multiplatform support :)
