[PATCH v2 1/9] spl: Try to get SPL boot device via board_get_int

[Jagan Teki]

Usually, the associated board would supply spl boot device
using spl_boot_device() but some boards have board driver
that are possible to supply boot device via board_get_int
with BOARD_SPL_BOOT_DEVICE id.

This patch add support for those.
