Signed-off-by: Hyungwon Hwang human.hwang@samsung.com Reviewed-by: Sjoerd Simons sjoerd.simons@collabora.co.uk Tested-by: Sjoerd Simons sjoerd.simons@collabora.co.uk Acked-by: Simon Glass sjg@chromium.org Tested-by: Kevin Hilman khilman@linaro.org Cc: Minkyu Kang mk7.kang@samsung.com Cc: Lukasz Majewski l.majewski@samsung.com Cc: Sjoerd Simons sjoerd.simons@collabora.co.uk Cc: Javier Martinez Canillas javier@dowhile0.org Cc: Simon Glass sjg@chromium.org --- Changes for v3: - Remove unnecessary node from DT file - Remove unnecessary features from config file - Remove unnecessary macros from board-specific header file - Fix some trivial typos in comments
Changes for v4: - Add MMC FIFO buffer's configuration to DT file - Make CONFIG_OF_CONTROL be set by the target information - Add basic document to doc/README.odroid-xu3 - Add CONFIG_CMD_EXT4 to config file - Add environment size and offset to config file - Add extra default environment to make bootable without modification - Remove unnecessary features from config file
Changes for v5: - Convert /include/ to #include in DT file
Changes for v6: - Separate out the documentation to new commit - Remove unnecessary header file inclusions from the board-specific setup file - Make the function board_clock_init be declared, only when CONFIG_BOARD_EARLY_INIT_F is defined
Changes for v7: - Remove OF_CONTROL dependency from !SPL_BUILD
Changes for v8: - Remove unnecessary properties in DT mmc node
Changes for v9: - Remove useless variables in the default environment - Replace the detailed information to the reference to the documentation
Changes for v10: - Remove the config unsets which are added to make the result image small This is needless now, because the image is not small enough even though these unsets are added. - Remove redundant DT node and properties - Remove the odroid-xu3 board file and make odroid-xu3 a variant of smdk5420
Changes for v11: - Remove duplicated CONFIG_CMD_EXT2/EXT4/FAT from odroid_xu3.h - Fix the typo in the comment, which is found in odroid_xu3.h
