powerpc/mpc8xx: Zero boot_flags arg for calling board_init_f()
Copied from e83a7e94532 ("powerpc/mpc83xx: Zero boot_flags arg for calling board_init_f()") The argument boot_flags of board_init_f() is not used at all in the powerpc specific board.c init sequence. Now with the generic init sequence, this boot_flags arg is used by board_init_f(). This patch sets the r3 register that is used to pass the boot_flags argument from the start.S board_init_f() call to 0 prior to the function call to avoid unknown content to end up in gd->flags. Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Fixes: 09f3ca3dd53 ("arm, powerpc: select SYS_GENERIC_BOARD")
