49cbcfb5e6 drivers/mmcsd/mmcsd.h|mmcsd_sdio.c|mmcsd_sdio.h: support MMC high speed SDR mode 
According to the eMMC specification, in Backwards Compatibility
with legacy MMC card mode, the frequency of the SD clock must be
0-26 MHZ; in high speed SDR mode, it must be 0-52MHZ. So we should
switch to high speed SDR mode if the clock frequency is higher than
26MHZ.

08ce36d292 drivers/mmcsd/mmcsd_sdio.c|h: optimize macros for setting EXT_CSD 
CMD6 can use these macros to set any writable EXT_CSD field, not
just the bus width, so optimize these macro definitions to make
them general.

92890552f1 drivrs/mmcsd: Partial reversion of commit 17b6c7ba39. Backed out all block callback logic controlled CONFIG_SDIO_BLK_CALLBACK. Usage of this feature by applications is a blatant violation of the POSIX interface standard. 2018-07-20 10:08:01 -06:00

17b6c7ba39 drivers/mmcsd/mmcsd_sdio.c: Fix an error that was causing SDIO multiple block transfers from achieving full performance. Also adds a feature controlled by CONFIG_SDIO_BLK_CALLBACK that bypasses the normal mechanism for obtaining sector data for transfer. 2018-07-20 09:55:33 -06:00
