Signed-off-by: Boris Schmidt Reviewed-by: Heiko Schocher Cc: Andreas Bießmann Cc: Bo Shen --- - changes for v2: - add comments from Bo Shen - use gpio api - remove unneccessary comment - use at91_wait_for_reset() - remove unneccessary code in board file - Coding Style cleanup (tabs and unneccessary 1 after config define removed, use ".xxx = x" notation for initializing structs) - remove reset_phy() - remove CONFIG_SYS_MEMTEST_x defines, as mtest command is not used on this board. - changes load address - delete lcd support - add comments from Andreas Bießmann: - rearrange some init calls - remove some unneeded ifdef --- board/siemens/corvus/Makefile | 39 ++++++++ board/siemens/corvus/board.c | 216 ++++++++++++++++++++++++++++++++++++++++++ boards.cfg | 1 +
