board: sifive: overwrite board_fdt_blob_setup in u-boot proper Add board_fdt_blob_setup to return the device tree location which is passed by prior stage in u-boot proper. The generic board_fdt_blob_setup always returns _end, it mignt be ok because u-boot SPL would currently put the dtb there, but it would be broken if we put the dtb to another place and assigned the location into a1 register for u-boot proper. Use the location passed by prior stage would make more sence, because we actually pass the location to u-boot proper and want to use that one, rather than the dtb which in _end. We can't use CONFIG_OF_PRIOR_STAGE because it doens't distinguish the implementation of u-boot SPL and u-boot proper, so u-boot SPL need to reply on the prior stage to pass device tree location as well, but we don't pass the DT from boot rom now. In addition, when CONFIG_OF_PRIOR_STAGE is enabled, the u-boot-spl.bin and u-boot.itb won't include the device tree.

riscv: sifive: Fix OF_BOARD boot failure When using QEMU to have a quick test of booting U-Boot S-mode payload directly without the needs of preparing the SPI flash or SD card images for SiFive Unleashed board, as per the instructions [1], it currently does not boot any more. This was caused by the OF_PRIOR_STAGE removal, as gd->fdt_blob no longer points to a valid DTB. OF_BOARD is supposed to replace OF_PRIOR_STAGE, hence we need to add the OF_BOARD logic in board_fdt_blob_setup().

board: sifive: Fix a potential build warning in board_fdt_blob_setup() Commit 47d73ba4f4a4 ("board: sifive: overwrite board_fdt_blob_setup in u-boot proper") added a board-specific implementation of board_fdt_blob_setup() which takes a pointer as the return value, but it does not return anything if CONFIG_OF_SEPARATE is not enabled.
