We have finished Generic Board conversion for ARM and PowerPC, i.e. all the boards have been converted except OpenRISC, SuperH, SPARC, which have not supported Generic Board framework yet. Select SYS_GENERIC_BOARD in arch/Kconfig and delete all the macro defines in include/configs/*.h. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
