Is booting SPL from entirely from SRAM only useful in concert with OPTEE? For instance, if I'm building a device that doesn't use OPTEE and yet want it to be secure, would I want to keep the SPL entirely in SRAM? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
