mmc: Fixes for Dual Data Rate (DDR) support
The DDR support patch needs the following fixes: - The block driver does not need to know about DDR, any more than it needs to know about bus width. - Not only the card must be switched to DDR mode. The host controller must also be configured, which is done through the 'set_ios()' function. - Do not set the DDR mode state until after the switch command is successful. - Setting block length is not supported in DDR mode. Make that a core function and change the other place it is used (mmc_test) also. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Chris Ball <cjb@laptop.org>
