7bf38161af mx53ard: Fix error handling in board_mmc_init()
When an invalid USDHC port is passed we should return -EINVAL instead of 0.

Also, return the error immediately on fsl_esdhc_initialize() failure.

68fbc0e686 imx: mx53ard: Add support for NAND Flash
Add support for the Samsung K9LAG08U0M NAND Flash (2-GiB MLC NAND Flash, 2-kiB
pages, 256-kiB blocks, 30-ns R/W cycles, 1 CS) on mx53ard.

eNFC_CLK_ROOT is set up with a cycle time of 37.5 ns (400 MHz / 3 / 5) for this
board, which satisfies the 30-ns NF R/W cycle requirement.

a2ac1b3a7d mxc: Fix SDHC multi-instance clock
On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not
suitable for the multi-instance use case (initialization made directly with
fsl_esdhc_initialize()).

This patch fixes this issue by adding a configuration field for the SDHC input
clock frequency.

16e43f354d fsl_esdhc: Remove cache snooping for i.MX
The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so
disable it globally for this architecture. This avoids setting no_snoop for all
i.MX boards, and it prevents setting a reserved bit of a reserved register if
fsl_esdhc_mmc_init() is used on i.MX, like in
arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init().

Since no_snoop was only used on i.MX, get rid of it BTW.

19db9be4aa mx53ard: Initialize return code with error
The variable "rc" is the return of board_eth_init() function. Initialize
it with an error code, so that this function can return an error when
CONFIG_SMC911X is not set.

314284b156 mmc: Change board_mmc_getcd() function prototype.
The new API no longer uses the extra cd parameter that was used to store
the card presence state. Instead, this information is returned via the
function's return value. board_mmc_getcd() returns -1 to indicate that
no card-detection mechanism is implemented; 0 indicates that no card is
present and 1 is returned if it was detected that a card is present.

The rationale for this change can be found in the following email
thread:

	http://lists.denx.de/pipermail/u-boot/2011-November/110180.html

In summary, the old API was not consistent with the rest of the MMC API
which always passes a struct mmc as the first parameter. Furthermore the
cd parameter was used to mean "card absence" in some implementations and
"card presence" in others.

a55d23ccf6 Remove volatile qualifier in get_ram_size() calls
Checkpatch.pl complains about the volatile qualifier in calls to

calls where it is useless, and leave it only in the function body
where it is needed.
