soc/mediatek/mt8192: add spmfw loader
This patch adds support for loading spm firmware from cbfs to spm sram. Spm needs its own firmware to enable spm suspend/resume function which turns off several resources such as DRAM/mainpll/26M clk when linux system suspend. BUG=b:159079649 TEST=suspend with command `powerd_dbus_suspend` and wake up the DUT by powerkey Signed-off-by: Roger Lu <roger.lu@mediatek.com> Change-Id: I6478b98f426d2f3e0ee919d37d21d909ae8a6371 Reviewed-on: https://review.coreboot.org/c/coreboot/+/46389 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Hung-Te Lin <hungte@chromium.org>
