'remotes/palmer/tags/riscv-for-master-4.2-sf1-v3' into staging RISC-V Patches for the 4.2 Soft Freeze, Part 1, v3 This contains quite a few patches that I'd like to target for 4.2. They're mostly emulation fixes for the sifive_u board, which now much more closely matches the hardware and can therefor run the same fireware as what gets loaded onto the board. Additional user-visible improvements include: * support for loading initrd files from the command line into Linux, via /chosen/linux,initrd-{start,end} device tree nodes. * The conversion of LOG_TRACE to trace events. * The addition of clock DT nodes for our uart and ethernet. This also includes some preliminary work for the H extension patches, but does not include the H extension patches as I haven't had time to review them yet. This passes my OE boot test on 32-bit and 64-bit virt machines, as well as a 64-bit upstream Linux boot on the sifive_u machine. It has been fixed to actually pass "make check" this time. Changes since v2 (never made it to the list): * Sets the sifive_u machine default core count to 2 instead of 5. Changes since v1 <20190910190513.21160-1-palmer@sifive.com>: * Sets the sifive_u machine default core count to 5 instead of 1, as it's impossible to have a single core sifive_u machine. # gpg: Signature made Tue 17 Sep 2019 16:43:30 BST # gpg: using RSA key 00CE76D1834960DFCE886DF8EF4CA1502CCBAB41 # gpg: issuer "palmer@dabbelt.com" # gpg: Good signature from "Palmer Dabbelt <palmer@dabbelt.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmer@sifive.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 * remotes/palmer/tags/riscv-for-master-4.2-sf1-v3: (48 commits) gdbstub: riscv: fix the fflags registers target/riscv: Use TB_FLAGS_MSTATUS_FS for floating point target/riscv: Fix mstatus dirty mask target/riscv: Use both register name and ABI name riscv: sifive_u: Update model and compatible strings in device tree riscv: sifive_u: Remove handcrafted clock nodes for UART and ethernet riscv: sifive_u: Fix broken GEM support riscv: sifive_u: Instantiate OTP memory with a serial number riscv: sifive: Implement a model for SiFive FU540 OTP riscv: roms: Update default bios for sifive_u machine riscv: sifive_u: Change UART node name in device tree riscv: sifive_u: Update UART base addresses and IRQs riscv: sifive_u: Reference PRCI clocks in UART and ethernet nodes riscv: sifive_u: Add PRCI block to the SoC riscv: sifive_u: Generate hfclk and rtcclk nodes riscv: sifive: Implement PRCI model for FU540 riscv: sifive_u: Update PLIC hart topology configuration string riscv: sifive_u: Update hart configuration to reflect the real FU540 SoC riscv: sifive_u: Set the minimum number of cpus to 2 riscv: hart: Add a "hartid-base" property to RISC-V hart array ...

2019-09-17riscv: sifive_u: Fix broken GEM supportBin Meng3-5/+23
At present the GEM support in sifive_u machine is seriously broken. The GEM block register base was set to a weird number (0x100900FC), which for no way could work with the cadence_gem model in QEMU. Not like other GEM variants, the FU540-specific GEM has a management block to control 10/100/1000Mbps link speed changes, that is mapped to 0x100a0000. We can simply map it into MMIO space without special handling using create_unimplemented_device(). Update the GEM node compatible string to use the official name used by the upstream Linux kernel, and add the management block reg base & size to the <reg> property encoding.
