93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

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.

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.

Updated mx53 ddr3 script in order to align with the latest Freescale version from July 8, 2011:
-change ESDREF[REF_SEL]=01 (for 32KHz), from incorrect setting of 00 (64KHz)
-change DDR3 MR0 write to "setmem /32 0x63fd901c = 0x052080b0" from
"0x092080b0". This changes write recovery from 8 clocks to 6 clocks
(in line with ESDCFG1[tWR])
