3d187b3924 cmd_bootm.c: Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPS
In 5c427e4 we pass BOOTM_STATE_OS_CMDLINE as part of the bootm states to
run, on all arches.  However, this is only valid / useful on PowerPC and
MIPS, and causes a problem on ARM where we specifically do not use it.
Rather than make this state fake pass like we do for GO on some arches
(which need updating to use the GO state), we should just not pass
CMDLINE except when it may be used, like before.

fe1378a961 ARM: use r9 for gd
To be more EABI compliant and as a preparation for building
with clang, use the platform-specific r9 register for gd
instead of r8.

note: The FIQ is not updated since it is not used in u-boot,
and under discussion for the time being.

The following checkpatch warning is ignored:
WARNING: Use of volatile is usually wrong: see

3102274d8b ARM: refactor compiler options in config.mk

373d798394 arm: prevent using movt/movw address loads
The movt/movw instruction can be used to hardcode an
memory location in the instruction itself. The linker
starts complaining about this if the compiler decides
to do so: "relocation R_ARM_MOVW_ABS_NC against `a local
symbol' can not be used" and it is not support by U-boot
as well. Prevent their use by requiring word relocations.
This allows u-boot to be build at other optimalization
levels then -Os.

9721027aae am335x_evm: am33xx_spl_board_init function and scale core frequency
Add a am33xx_spl_board_init (and enable the PMICs) that we may see,
depending on the board we are running on.  In all cases, we see if we
can rely on the efuse_sma register to tell us the maximum speed.  In the
case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz.  In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1.  As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe.  In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.

2c011847c1 Fix wrong sdhci host control register read and write
The patch fixes the improper read and write of sdhci
host control register for sdma transfer.

The problem comes when reading and writing 1 byte long
host control register with the sdhci_readl() and
sdhci_writel(). The misuse of these functions overwrite
the value of the next registers which are in 4 bytes boundary.

This patch replaces four byte register read/write functions
with one byte read/write ones. Beside, it eliminates
unnecessary bit operation. i.e. or-ing zero against a variable.

2136d22630 mmc/dw_mmc: Fix DMA descriptor corruption
In dwmci_prepare_data, the descriptors are allocated for DMA transfer.
These are allocated using the ALLOC_CACHE_ALIGN_BUFFER. This macro uses
the stack to allocate these descriptors. This becomes a problem if the
DMA transfer continues after the processor leaves the function in which
the descriptors were allocated.

Therefore, I have moved the allocated of the buffers up one level, to
dwmci_send_cmd(). The DMA transfer should be complete when leaving this
function.

it works fine as it did before.
