Put specific members under #ifdef (CONFIG_STORAGE & STORAGE_xx) (2 members for SD and 1 for MMC) Fix a typo: tsac doesn't exist and must be read taac Move card_get_info functions declaration inside hotswap.h to remove mutual inclusion of ata_mmc.h and hotswap.h Move static const data structures from SD drivers into sd.h (sd_exponent and sd_mantissa) Fix sd_command prototypes in SD drivers (card registers are unsigned long) Fix speed calculation in Sansa AMS driver (PP SD driver needs to be checked) Move ata-sd-target.h to sd-pp-target.h to reflect the PP specifity. Now it only contains declaration of microsd_int() Remove unused ata-sd-target.h for injenic TODO: - check if CSD register bits are extracted correctly in PP driver - correctly define read_timeout and write_timeout unit for MMC & SD, and use timeouts in Sansa AMS driver git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21586 a1c6a512-1295-4272-9138-f99709370657
