I do have check some of the implement and most of them should be OK, but to be honest, I'm don't have any of those boards, and not sure if this break any of them, and I'm not sure if people using this interface have notice it's after the board_init(). When I try to use this board_early_init_r(), I thought this is before board_init(), but it actually after the board_init(), that make people confusing. I think the _early_ one should be at the first, isn't it?

Maybe we should rename it to board_post_init? Sorry , do you mean add/rename a board_post_init() for what's done by board_early_init_r() now and then add/move ad board api before board_init()? There is a board_late_init(), which is after env init, a new board_post_init() seems not a good idea. Here is the Kconfig help for BOARD_EARLY_INIT_R, which also means we it should be called before board_init(). config BOARD_EARLY_INIT_R bool "Call board-specific init after relocation" help Some boards need to perform initialisation as directly after relocation. With this option, U-Boot calls board_early_init_r() in the post-relocation init sequence. Thanks, - Kever > > Regards, > Matthias > ^ permalink raw reply [flat|nested] 8+ messages in thread

If we really cannot, then let's rename board_early_init_r() to board_init_powerpc() for now.

I wonder whether any board is actually using both board_init() and board_early_init_r(). To me they serve the same function.
