Apologies for the late reply. I was working on some other stuff and
hence this got put on the backburner. With regards to your review
comment of putting the board code under board/radxa/, how do I get the
code under board/radxa to compile. The RockPi4 boards have
CONFIG_SYS_VENDOR="rockchip" and CONFIG_SYS_BOARD="evb_rk3399". With
these configs, code under board/rockchip/evb_rk3399/ gets built. Is
there some way I can get code under some other board directory to
build?
I was thinking of putting the common code under
arch/arm/mach-rockchip/board.c, and the board specific declarations
under board/rockchip/evb_rk3399/evb_rk3399.c, along with the splitting
of the changes in two patches. Is that fine with you?
