Reduce the MMC clock frequency slightly to make all cards work. Otherwise weird CRC errors seem to happen with many RS-MMC cards. Signed-off-by: Juha Yrjölä <juha.yrjola at nokia.com>

The MMC spev v4.1 has table 23 on page 65 listing the valid response bits from each command. The table specifies CMD12 response not containing bit 31 (address out of range) and only 23, 22, and 20 (command crc, illegal command and card error) error bits and some status bits are defined.

This updates the MMC initialization: - OMAP_TAG_MMC updates: * Re-factor contents into one struct per silicon block * Provide information that's useful for SD support, like whether the board is wired for 4-wire transfers and what gpio (if any) is used to sense the writeprotect slider. * Allows for "nonstandard" muxing options, which would mostly affect boards using MMC2. * Report whether the MMC switch should use the card detect model, or the cover switch model. * Updated/tested board config only for H2 (not H3 or VoiceBlue). - MMC device initialization moved into mach-omap/omap1/device.c and out of the MMC driver itself. - Removed the "what MMC blocks to configure" option from Kconfig; the board-specific MMC tag holds this info (and more). This new device init hook should be easy to reuse to set up any of the other integrated devices. Signed-off-by:

[PATCH] ARM: OMAP: MMC updates (SD works) MMC updates, most significantly for DMA: - Handle small requests like 8 bytes ... this means that the SD patches work on OMAP, in bare-bones mode (that is, no writeprotect detection or 4-bit parallel I/O). - Avoid funky half-FIFO-size DMA transfers (they seemed to wedge in one test). - Use packing and bursting for cheaper EMIFF/memory accesses. Plus a few cleanups: compiler warnings, comments, init/exit sections, clk use/unuse, and keeping some line lengths below 80 characters. Signed-off-by:

[PATCH] ARM: OMAP: omap edge trigger call updates This switches over to using the standard ARM-Linux set_irq_type() call instead of its OMAP-specific variant, and removes the OMAP variant. It also tweaks the SMC driver to include a change requested by the maintainer of that driver. Signed-off-by:
