CONFIG_ARCH_OMAP2PLUS depends on (ARCH_MULTI_V6 || ARCH_MULTI_V7) as of
a0694861 "ARM: OMAP2+: Enable ARCH_MULTIPLATFORM support", but the
individual OMAP2/3/4/5 and AM33XX platforms can all be selected independent
of what we are building for, which is a bug and prevents us from easily
building e.g. an ARMv7-only defconfig.
This makes ARCH_OMAP2 depend on ARCH_MULTI_V6 and the others depend on
ARCH_MULTI_V7, to ensure we really only build the platforms for the
CPUs we have enabled in the global multiplatform configuration step.

When building the kernel with CONFIG_THUMB2_KERNEL enabled, older
assemblers may emit the following error:
reset-handler.S:78: Error: invalid immediate for address calculation (value = 0x00000004)
Using an explicit adr.w instruction will solve this. Newer assemblers do
this automatically. Use the W() macro to do this under Thumb mode only.

The linker will fail when the conditional branch over the range. Then
resulting in link error when generating kernel image. e.g.:

Some minor fixes for MSM for 3.10
- Fix a timer problem that causes missed ticks and hangs.
- Fix a problem with the decompressor UART dropping characters.
* tag 'msm-fix-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm:
ARM: msm: Fix uncompess.h tx underrun check
ARM: msm: Stop counting before reprogramming clockevent
Signed-off-by: Olof Johansson <olof@lixom.net>
Bit 3 of the SR register is set if there is a tx underrun. If
this bit isn't set, we should loop on the tx ready bit until we
can transmit again. Otherwise we should skip the loop and
transmit immediately. The code is doing the opposite though,
checking for an underrun and then looping on the tx ready bit
causing us to never loop on the tx read bit when the tx buffer
may not be ready.
This doesn't seem to affect my 8960 device too often, but in some
cases I see a lost character or two from the decompressor prints.
This also matches what we do in the assembly in debug-macro.S.

omap3_noncore_dpll_set_rate() attempts an enable of bypass clk as well
as ref clk for every .set_rate attempt on a noncore DPLL, regardless of
whether the .set_rate results in the DPLL being locked or put in bypass.
Early at boot, while some of these DPLLs are programmed and locked
(using .set_rate for the DPLL), this causes an ordering issue.
For instance, on OMAP5, the USB DPLL derives its bypass clk from ABE DPLL.
If a .set_rate of USB DPLL which programmes the M,N and locks it is called
before the one for ABE, the enable of USB bypass clk (derived from ABE DPLL)
then attempts to lock the ABE DPLL and fails as the M,N values for ABE
are yet to be programmed.
To get rid of this ordering needs, enable bypass clk for a DPLL as part
of its .set_rate only when its being put in bypass, and only enable the
ref clk when its locked.

WDT1 module can take one of the below clocks as input functional
clock -
- On-Chip 32K RC Osc [default/reset]
- 32K from PRCM
The On-Chip 32K RC Osc clock is not an accurate clock-source as per
the design/spec, so as a result, for example, timer which supposed
to get expired @60Sec, but will expire somewhere ~@40Sec, which is
not expected by any use-case.
The solution here is to switch the input clock-source to PRCM
generated 32K clock-source during boot-time itself.

This patch adds sysc definitions to the wdt1 hwmod entry, which in-turn
makes sure that sysc idle bit-fields are configured to valid state on
enable/disable callbacks.
With the recent submitted patch from Santosh Shilimkar,
"ARM: OMAP2+: hwmod: Don't call _init_mpu_rt_base if no sysc"
(commit: 4a98c2d89), it is required to add sysconf
information to each valid hwmod entry, else device will not be

Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc
region), the Cavium CNS3xxx cannot boot anymore.
This is caused by the pre-defined iotable mappings is not in the vmalloc
region. This patch move the iotable mappings into the vmalloc region, and
merge the MPCore private memory region (containing the SCU, the GIC and
the TWD) as a single region.

For 32-bit, CONFIG_EPAPR_PARAVIRT pulls in both epapr_paravirt.c
and epapr_hcalls.c which contains the 32-bit paravirt idle loop.
For 64-bit, the paravirt idle loop is in idle_book3e.S and that
source file is included only if CONFIG_PPC_BOOK3E_64 defined.
This patch makes that dependency for 64-bit explicit.
