[PATCH] treewide: Remove empty board_init() function from all boards

[Peng Fan]

> Subject: [PATCH] treewide: Remove empty board_init() function from
> all boards
> 
> Commit 86acdce2ba88 ("common: add config for board_init() call")
> introduced CONFIG_BOARD_INIT option. This option can be disabled
> for the
> boards where board_init() function is not needed. Remove empty
> board_init() calls for all boards where it's possible, and disable
> CONFIG_BOARD_INIT in all related defconfigs.
> 
> This cleanup was made semi-automatically using these scripts: [1].
> 
> No functional change, but the binary size for the modified boards is
> reduced a bit.

> Although I did this cleanup as carefully as I could, and ran buildman

> There are only two remaining board files having empty board_init()

>     $ grep -Pzrl "\bboard_init\(void\)\n{\n.*return 0;\n}\n" board/
> 
>     board/BuR/zynq/common/board.c
>     board/renesas/common/rcar64-common.c
> 
> The first one only has empty board_init() in case of U-Boot proper
> build, but it's not empty in case of SPL build. The second one has
> __weak board_init(), so it should be left as is, as it's a common board
> file which can be used by specific board files later.
> 
> This patch only reworks board/ directory, so arch/ has to be handled
> separately later.
