For MMC_BUS_WIDTH_8 case, current code missed setting BM_EIGHTBIT_MODE bit. Also has a small refactor to make the code looks better in readability. So the bit settings witch below logic: SDMMC_BUSMODE register: Set EIGHTBIT_MODE bit for 8 bit mode, Set FOURBIT_MODE bit for 4 bit mode. Clear both EIGHTBIT_MODE and FOURBIT_MODE bits for 1 bit mode. SDMMC_EXTCTRL register: Set EXT_EIGHTBIT bit for 8 bit mode, Clear EXT_EIGHTBIT bit for 1/4 bit mode. Add define for EXT_EIGHTBIT to avoid using magic number. BM_ONEBIT_MASK is no longer used, thus remove it. This patch is untested due to lack of platform with 8-bit hardware. However since the code is there, it's good to make the code match the document. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |
