OMAP4: fix omap4_bootsource regression ...

commit d7a9134 breaks boot source detection
for pcm049. The tracing vectors shows all tested boot sources, so order is
important. By not returning but overwriting src we effectively reversed the
order if more than one flag is set.

ARM v7: added v7_mmu_cache_invalidate() ...

At least the iMX6 boot rom seems to jump into barebox with a non
invalidated d-cache which causes data corruption when
v7_mmu_cache_flush() executed by arm_early_mmu_cache_flush() overrides
stack or other valid data.

That's why the cache must be invalided for this processors explicitly
(e.g. in barebox_arm_reset_vector()).  Operation differs from flush only
in one instruction so that patch modifies the existing
v7_mmu_cache_flush() function slightly by adding an optional argument.

ARM: fix the memset fix ...

From Kernel commit 418df63a ARM: 7670/1: fix the memset fix

| Commit 455bd4c430b0 ("ARM: 7668/1: fix memset-related crashes caused by
| recent GCC (4.7.2) optimizations") attempted to fix a compliance issue
| with the memset return value.  However the memset itself became broken
| by that patch for misaligned pointers.
|
| This fixes the above by branching over the entry code from the
| misaligned fixup code to avoid reloading the original pointer.
|
| Also, because the function entry alignment is wrong in the Thumb mode
| compilation, that fixup code is moved to the end.
|
| While at it, the entry instructions are slightly reworked to help dual
| issue pipelines.

ARM v7: fix mmu-off operation ...

Although conclusions in 50d1b2d "ARM
v7: Fix register corruption in v7_mmu_cache_off" are correct, the
implemented fix is not complete because the following failure can
happen:

1. d-cache contains the cache line around 'sp'

2. v7_mmu_cache_off() disables cache

3. early v7_mmu_cache_flush() pushes 'lr' on uncached stack

4. v7_mmu_cache_flush() flushes d-cache and can override stack written
   by step 3.

5. v7_mmu_cache_flush() pops 'lr' out of cache and jumps to it which
   might be random data now.

Patch avoids step 3 which is easy because 'lr' is never modified by the
function.  By using the 'r12' scratch register instead of 'r10', the
whole initial 'push' can be avoided.

Patch moves also the 'DMB' operation so that it is executed after data
has been pushed on stack.

When the dhcp code discovered the tftp-server-name option it immediately
tries to resolve the name. This can't succeed since the we are somewhere
in the dhcp processing and the nameserver may not even be known.

Fix this by resolving the name when dhcp is completed. While at it, do
this in a way that net_set_serverip is only called when resolv() returns
something useful. Otherwise we may end up overwriting a previously
configured serverip which came from the bootp bp_siaddr field.

MCI/MXS: fix signed/unsigned mismatch ...

Using the MXS MCI driver with an eight bit capable eMMC results into the
'devinfo' message the interface uses '0' bits for data transfer:

 barebox:/ devinfo mxs_mci0
 resources:
 num   : 0
 start : 0x80034000
 size  : 0x00002000
 driver: mxs_mci
 bus: platform

  Interface
   Min. bus clock: 1476 Hz
   Max. bus clock: 48000000 Hz
   Current bus clock: 24000000 Hz
   Bus width: 0 bit

The eight bit interface width is stored internally as value '2'. And a two bit
'2' ends up into 0xfffffffe when used as an array index. Using an unsigned
field instead fixes this issue:

 barebox:/ devinfo mxs_mci0
 resources:
 num   : 0
