[U-Boot] [PATCH 0/4] generic mmc_spi driver

[Thomas Chou]

This is the v9 update of the mmc_spi driver. Please enable DEBUG on the top of
mmc_spi.c and help me perform the tests.

A new spi_set_speed() is added to meet the 400KHz clock requirement during mmc card
initialization. An example update to bfin_spi is included. The altera_spi core does
not support speed change, so I am going to post a new opencore ip for this.

The driver now claims and releases the spi bus for each mmc command, as Mike suggested.

Thomas Chou (4):
  lib: add crc7 from Linux
  spi: add spi_set_speed func
  bfin_spi: add spi_set_speed
  mmc: add generic mmc spi driver
