I want enable signed images(RSA/ECC sign&verify)
BootROM verifies the signature of the next bootloader with respect to ROTPK(public key in efuse area).
I have downloaded your sdk (BPI-M2P-bsp-master) and it is well organised.
There is one folder: AllWinnerH3/BPI-M2P-bsp-master/u-boot-sunxi/sunxi_spl/sbrom what is this folder?
We want use H3 soc, but there is no proper information Secure boot sequence and Building Root Of trust.
