From 2e8d2f88439d7437f04a6af1d206270f9a2240d3 Mon Sep 17 00:00:00 2001 From: Ilias Apalodimas Date: Tue, 12 Oct 2021 00:00:13 +0300 Subject: riscv: Remove OF_PRIOR_STAGE from RISC-V boards At some point back in 2018 prior_stage_fdt_address and OF_PRIOR_STAGE got introduced, in order to support a DTB handed over by an earlier stage boo loader. However we have another option in the Kconfig (OF_BOARD) which has identical semantics. On RISC-V some of the boards pick up the DTB from a1 and copy it in their private gd_t. Apart from that they copy it to prior_stage_fdt_address, if the Kconfig option is selected, which is unnecessary. So let's switch the config option for those boards to OF_BOARD and define the required board_fdt_blob_setup() for them.
