[RESEND PATCH 0/2] ARM: make DaVinci part of the ARM v5 multiplatform build

[RESEND PATCH 0/2] ARM: make DaVinci part of the ARM v5 multiplatform build

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Resending rebased on top of v5.1-rc1.

This series depends on the clocksource rework that's been earlier
posted to LKML[1].

The first one adds necessary bits and pieces for davinci to support
multiplatform build and the second one actually adds all davinci boards
to multi_v5_defconfig.

[RESEND PATCH 1/2] ARM: davinci: support multiplatform build for ARM v5

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Add modifications necessary to make davinci part of the ARM v5
multiplatform build.

Move the arch-specific configuration out of arch/arm/Kconfig and
into mach-davinci/Kconfig. Remove the sub-menu for DaVinci
implementations (they'll be visible directly under the system type.
Select all necessary options not already selected by ARCH_MULTI_V5.
Update davinci_all_defconfig. Explicitly include the mach-specific
headers in mach-davinci/Makefile.

I like this a lot, it gives me some hope that we can eventually
do the same for the remaining ARMv5 platforms that are
not multiplatform yet (s3c24xx, ks8695, w90x900, lpc32xx,
omap1, ep93xx, and maybe even the xscale based ones).

I have done a lot of randconfig testing with this patch appled now
and not found any issues, great work!

Thanks Arnd. Will take this as your Acked-by:

The timer conversion patches are pending review/rework. Will queue once
those are cleared.

Unfortunately, after doing some more randconfig testing, I ended up with
three build issues:

1. vpbe:
drivers/media/platform/davinci/vpbe_osd.c:29:10: fatal error:
'mach/cputype.h' file not found

2. staging/vpfe:

'mach/mux.h' file not found

3.
    davinci: fix sleep.S build error on ARMv4

    When building a multiplatform kernel that includes armv4 support,
    the default target CPU does not support the blx instruction,
    which leads to a build failure:

    arch/arm/mach-davinci/sleep.S: Assembler messages:
    arch/arm/mach-davinci/sleep.S:56: Error: selected processor does
not support `blx ip' in ARM mode

    Add a .arch statement in the sources to make this file build.

Hi Arnd,

are the generated configs available somewhere for download?

No, I only keep them locally, but I would hope they are easy enough to
reproduce. If you can't figure out the problem right away, I can send
you the config files of course.

Just noticed another issue in my logs:

4. ARCH_DAVINCI no longer selects RESET_CONTROLLER
drivers/clk/davinci/psc.o: In function `__davinci_psc_register_clocks':
psc.c:(.text+0x3f8): undefined reference to `devm_reset_controller_register'

Thanks. Another issue that I already fixed locally is missing select
for REGMAP_MMIO. Just FYI.

This series is blocked by the clocksource series anyway, but I'll work
towards fixing it.
