Cover letter [U-Boot] [PATCH 0/3] RISC-V S-mode support
This patchset allows us runing u-boot in S-mode.
This is particularly useful on platforms where M-mode runtime firmware is an independent firmware and u-boot is used as last stage OS bootloader.
The patchset is tested on QEMU in both M-mode and S-mode.
