drivers: synopsys: Fix synopsys MMC driver
There are some issues with synopsys MMC driver: - CMD8 should not expect data (for SD) - ACMD51 should expect data (Send SCR for SD) - dw_prepare should not dictate size to be MMC_BLOCK_SIZE, block size is now handled in the dw_prepare function - after the CMD completes, when doing dw_read, we need to invalidate cache and wait for the data transfer to complete - Need to set FIFO threshold, otherwise DMA might never get the interrupt to read or write Signed-off-by: Tien Hock, Loh <tien.hock.loh@intel.com> |
