2020-06-23hw/arm/mps2-tz: Use the ARM SBCon two-wire serial bus interfacePhilippe Mathieu-Daudé1-5/+18
From 'Application Note AN521', chapter 4.7: The SMM implements four SBCon serial modules: One SBCon module for use by the Color LCD touch interface. One SBCon module to configure the audio controller. Two general purpose SBCon modules, that connect to the Expansion headers J7 and J8, are intended for use with the V2C-Shield1 which provide an I2C interface on the headers.

2020-06-19hw/riscv: sifive_u: Add a dummy DDR memory controller deviceBin Meng1-0/+4
It is enough to simply map the SiFive FU540 DDR memory controller into the MMIO space using create_unimplemented_device(), to make the upstream U-Boot v2020.07 DDR memory initialization codes happy. Note we do not generate device tree fragment for the DDR memory controller. Since the controller data in device tree consumes a very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the U-Boot source), and it is only needed by U-Boot SPL but not any operating system, we choose not to generate the fragment here. This also means when testing with U-Boot SPL, the device tree has to come from U-Boot SPL itself, but not the one generated by QEMU on the fly. The memory has to be set to 8GiB to match the real HiFive Unleashed board when invoking QEMU (-m 8G). With this commit, 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 above exception is expected because QSPI is unsupported yet.

2020-06-19hw/riscv: sifive_u: Support different boot source per MSEL pin stateBin Meng1-8/+31
SiFive FU540 SoC supports booting from several sources, which are controlled using the Mode Select (MSEL[3:0]) pins on the chip. Typically, the boot process runs through several stages before it begins execution of user-provided programs. The SoC supports booting from memory-mapped QSPI flash, which is how start_in_flash property is used for at present. This matches MSEL = 1 configuration (QSPI0). Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL). It's not necessary for QEMU to implement the full ZSBL ROM codes, because we know ZSBL downloads the next stage program into the L2 LIM at address 0x8000000 and executes from there. We can bypass the whole ZSBL execution and use "-bios" to load the next stage program directly if MSEL indicates a ZSBL booting flow.
