FIP is accessed as memory-mapped type. eMMC is block device type. In order to support FIP based on eMMC, add the new io_block layer. io_block always access eMMC device as block size. And it'll only copy the required data into buffer in io_block driver. So preparing an temporary buffer is required. When use io_block device, MAX_IO_BLOCK_DEVICES should be declared in platform_def.h. It's used to support multiple block devices. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org> |
