From: Bin Meng <bin.m...@windriver.com> This series updates the 'sifive_u' machine support:
- Change SiFive E/U series CPU reset vector to 0x1004 - Support Mode Select (MSEL[3:0]) settings at 0x1000 via a new "msel" machine property - Add a dummy DDR memory controller device With this series, QEMU can boot U-Boot SPL built for SiFive FU540 all the way up to loading U-Boot proper from MMC: $ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800) Trying to boot from MMC1 Unhandled exception: Load access fault EPC: 0000000008009be6 TVAL: 0000000010050014 The last big gap for the 'sifive_u' machine is the QSPI modeling. Changes in v2: - Drop the already applied patch 01 to 11 in v1 - new patch: Rename IBEX CPU init routine - rebase on https://github.com/alistair23/qemu riscv-to-apply.next branch - rename SiFive E/U CPU init routine names Bin Meng (5): target/riscv: Rename IBEX CPU init routine hw/riscv: sifive: Change SiFive E/U CPU reset vector to 0x1004 hw/riscv: sifive_u: Support different boot source per MSEL pin state hw/riscv: sifive_u: Sort the SoC memmap table entries hw/riscv: sifive_u: Add a dummy DDR memory controller device hw/riscv/sifive_e.c | 10 +++++---- hw/riscv/sifive_u.c | 51 ++++++++++++++++++++++++++++++++++----------- include/hw/riscv/sifive_u.h | 7 +++++++ target/riscv/cpu.c | 20 +++++++++--------- 4 files changed, 62 insertions(+), 26 deletions(-) -- 2.7.4
