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.

21bd5761a6 mmc/dw_mmc: Allocate the correct amount of descriptors
This fixes two issues:

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.

fd37f195ca net: fec_mxc: Fix timeouts during tftp transfer
Performing tftp transfers on mx28 results in random timeouts.

Hector Palacios and Robert Hodaszi analyzed the root cause being related to the
wrong alignment of the 'buff' buffer inside fec_recv().

Benoît Thébaudeau provided an excellent analysis of the alignment bug that is
present on older versions, such as GCC 4.5.4:

http://marc.info/?l=u-boot&m=137942904906131&w=2

Use ALLOC_CACHE_ALIGN_BUFFER() to avoid alignment issues from older GCC
versions.

50c2a91b67 Makefile: Do not show make debug messages
In commit 27af930, the top Makefile was adjusted to the new

But at the same time, -d option was added.

If you configure and make separately, for example
like follows:

    make omap4_panda_config
    make CROSS_COMPILE=<your_compiler_prefix>

it works fine as it did before.

But if you do them in one time like follows:

    make omap4_panda CROSS_COMPILE=<your_compiler_prefix>

The log is sprinkled with annoying make debug messages.

But the state machine of netconsole don't take it into account.
Thus, netconsole calls network functions of an halted network device,

Rather than modifying the state machine of netconsole, we just unregister

5c427e49ce bootm: use BOOTM_STATE_OS_CMDLINE flag for plain bootm
A plain bootm used to call the architecture specific boot function with
no flags, but was modified by commit 35fc84fa "Refactor the bootm
command to reduce code duplication" to call the architecture specific
boot function multiple times with various flags in sequence. The
BOOTM_STATE_OS_CMDLINE flag was not used, indeed it seems that at least
ARM prepares the command line on BOOTM_STATE_OS_PREP. However on MIPS
since commit 59e8cbdb "MIPS: bootm: refactor initialisation of kernel
cmdline" the command line is not prepared in response to a
BOOTM_STATE_OS_PREP flag, only on BOOTM_STATE_OS_CMDLINE or a call with
no flags. The end result is that a combination of those 2 commits leads
to MIPS boards booting kernels with no command line arguments.

An extra invocation of the architecture specific boot function with
BOOTM_STATE_OS_CMDLINE fixes this.

8687d5c80c mmc: size optimization when !CONFIG_MMC_SPI
When CONFIG_MMC_SPI is not enabled, the MMC_MODE_SPI capability can
never be set. However there is code in mmc.c which uses the
mmc_host_is_spi macro to check that capability & act accordingly. If we
expand that macro to 0 when CONFIG_MMC_SPI is not set (since it will
always be 0 at runtime anyway) then the compiler can optimize away the
SPI-specific code paths in mmc.c.
