We are generally supposed to implement SoC/board-specific SPL init code in spl_board_init(), but it is called after spl_init() where the FDT is setup and devices are bound.
This new stub spl_early_board_init() would be useful to put something really SoC-specific, for example, debug_uart_init(). In fact, I was hit by some problems on FDT setup when I was tackling on a completely new platform. I wished I could use the debug UART earlier in situations like that.
