fastboot: sparse: fix block addressing for don't care chunk type

2016-04-12T00:48:29+00:00

When 7bfc3b1 (sparse: Refactor chunk parsing function) was implemented,
it dropped 9981945 (aboot: fix block addressing for don't care chunk type).

This re-implements the required fix for the "don't care chunk type"...

spl: mmc: raw: Try to load u-boot if Linux image is not found

2016-04-12T00:48:27+00:00

If CONFIG_SPL_OS_BOOT is enabled and Linux image is not flashed at
RAW_MODE_KERNEL_SECTOR in MMC, spl still assumes that Linux is
available and tries to boot it and hangs. In order to avoid this,
adding a check to verify if parsed image header is of type IH_OS_LINUX.
If it fails then fall back to load u-boot image.

arm: Replace v7_maint_dcache_all(ARMV7_DCACHE_INVAL_ALL) with asm code

2016-04-12T00:48:27+00:00

Lets be consistent and also replace v7_maint_dcache_all()
with asm code for the invalidate case.

arm: Replace v7_maint_dcache_all(ARMV7_DCACHE_CLEAN_INVAL_ALL) with asm code

2016-04-12T00:48:26+00:00

v7_maint_dcache_all() does not work reliable when build with gcc6,
see: https://bugzilla.redhat.com/show_bug.cgi?id=1318788

While debugging this I learned that v7_maint_dcache_all() is unreliable
when build with gcc5 too when it is marked as noinline.

This commit fixes the reliability issues by replacing the C-code with
the ready to use asm implementation from the kernel.

Given that this code when written as C-code clearly is quite fragile
(also see the existing comments about the C-code being the way it is
 to get optimal assembly) and that we have a proven asm alternative,
I believe that this is the best solution.

Note that we actually already had a copy of the kernel's
v7_flush_dcache_all() before this commit in
arch/arm/mach-uniphier/arm32/lowlevel_init.S.

This commit moves that code arch/arm/cpu/armv7/cache_v7_asm.S, renames
it to __v7_flush_dcache_all(), and adds a v7_flush_dcache_all() wrapper
which saves / restores the clobbered registers for use from C-code.

lib/crc8: Add crc start value

2016-04-12T00:48:26+00:00

To make the usage of this function more flexible, lets add the CRC start
value as parameter to this function. This way it can be used by other
functions requiring different start values than 0 as well.

For non-zero CRC start values to work, I've reworked the function a bit.
The new implementation is copied from the Linux version in
drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero
CRC stating values.

I've double-checked that the results for zero starting values are
identical to the results from the original version of this function.

test/py: README: link to example hook scripts

2016-04-12T00:48:25+00:00

When implementing test/py hook scripts, it's helpful to read some working
examples. Provide a link to some. The link was mentioned in the commit
message which first added test/py, but not in any documentation file.

bootcounter_ram: Flush dcache after data is written into SDRAM

2016-04-12T00:48:25+00:00

This patch adds a call to flush_dcache_range() to bootcount_store() to
make sure, that the bootcounter data (including the patterns) is
written to memory. Without this, platforms with dcache enabled may not
have the bootcounter updated upon reset.
