2016-08-12 | emmc: support CMD23 | Haojian Zhuang | |
Support CMD23. When CMD23 is used, CMD12 could be avoided. Two scenarios: 1. CMD17 for single block, CMD18 + CMD12 for multiple blocks. 2. CMD23 + CMD18 for both single block and multiple blocks. The emmc_init() should initialize whether CMD23 is supported or not. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org> | |||
2016-04-27 | drivers: add emmc stack | Haojian Zhuang | |
In a lot of embedded platforms, eMMC device is the only one storage device. So loading content from eMMC device is required in ATF. Create the emmc stack that could co-work with IO block driver. Support to read/write/erase eMMC blocks on both rpmb and normal user area. Support to change the IO speed and bus width. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org> |
