Bin Meng 145b299139 hw/riscv: sifive_u: Add QSPI0 controller and connect a flash ... This adds the QSPI0 controller to the SoC, and connects an ISSI 25WP256 flash to it. The generation of corresponding device tree source fragment is also added. Since the direct memory-mapped mode is not supported by the SiFive SPI model, the <reg> property does not populate the second group which represents the memory mapped address of the SPI flash. With this commit, upstream U-Boot for the SiFive HiFive Unleashed board can boot on QEMU 'sifive_u' out of the box. This allows users to develop and test the recommended RISC-V boot flow with a real world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to L2LIM, then U-Boot SPL loads the payload from SPI flash that is combined with OpenSBI fw_dynamic firmware and U-Boot proper. Specify machine property `msel` to 6 to allow booting from the SPI flash. U-Boot spl is directly loaded via `-bios`, and subsequent payload is stored in the SPI flash image. Example command line: $ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -smp 5 -m 8G \ -bios u-boot-spl.bin -drive file=spi-nor.img,if=mtd Signed-off-by: Bin Meng <bin.meng@windriver.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-id: 20210126060007.12904-5-bmeng.cn@gmail.com Signed-off-by: Alistair Francis <alistair.francis@wdc.com>		2021-03-04 09:43:29 -05:00
