Hi all,

Here are the remaining patches to be able to build omap2+
with multiplatform enabled. Booting requires disabling
ARM_ERRATA_751472 as discussed earlier. And then the
OMAP4_ERRATA_I688 can't be used currently.

These patches are based on a merge of the following branches
that are needed to keep things compiling:
     
- omap-for-v3.8/cleanup-headers-prepare-multiplatform-v3
- omap-for-v3.8/clock
- omap-for-v3.8/cleanup-headers-iommu
- omap-for-v3.8/pm-part2
- Tomi's branch 3.8/vram-conversion
- Russell's branch omap-serial

There are few drivers still breaking because of their
use of plat/cpu.h and cpu_is_omap macros. The following
already have patches queued in linux next:

- drivers/staging/omapdrm/omap_drv.c
- drivers/staging/omapdrm/omap_dmm_tiler.h

The fixes to following have been already posted:

- drivers/crypto/omap-sham.c

And the following should have patches coming:

- drivers/mfd/omap-usb-host.c
- drivers/media/platform/omap/omap_voutlib.c
- drivers/media/platform/omap3isp/isp.c

But for now, the last patch in this series is for
testing only.

Regards,

Tony

Recent changes to the omap_wdt.c removed the dependencies to
the core omap code, but forgot to remove mach/hardware.h.

We cannot include any plat headers with multiplatform
support enabled.

We cannot include any plat or mach headers for the multiplatform
support.

Fix the issue by defining local mcbsp_omap1().

We need to move this file to allow ARM multiplatform configurations
to build for omap2+. This can now be done as this file now only
contains platform_data.

Russell, this one depends on your commit fd9980c7 (SERIAL: omap:
remove OMAP_UART_SYSC_RESET and OMAP_UART_FIFO_CLR).

Is that commit immutable and OK to merge as a dependency to my
branch?

Regards,

Tony

Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.

Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.

So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.

The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.

Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.

Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.

Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.

Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

Not intended for merging yet as few more drivers need
work. You may need to update your config 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 too.

The omap2plus_defconfig has been updated in this patch.

Note that there's a bunch of OMAP drivers in staging which are trivially
broken anyway; I've not been bothering to report their breakages which
my build system is finding - I figure that if they're trivially broken
with compile time errors which aren't config related, and no one's
bothering to fixing them, then no one is even trying to build them -
which means they're not being used.

And if they're not being used, it's pointless them being in mainline.

Do you have a list of the broken drivers somewhere?

Yes makes sense to me.

No, I've been ignoring the error messages from anything in staging, so
it'll be a matter of digging through the last seven days build logs.
