The header file is not necessary in either of those files, remove it as common.h is going away. Include missing asm/arch/rmobile.h in board/renesas/rcar-common/v3-common.c to prevent build failure of r8a77970_eagle r8a779a0_falcon r8a77980_v3hsk and r8a77970_v3msk . Include missing asm/u-boot.h in falcon.c and grpeach.c to fix build failure due to missing definition of struct bd_info . Include errno.h in grpeach.c to fix build error due to missing definition of EINVAL.
