[sbi] Add support for running as a RISC-V SBI payload

2024-10-28T19:20:50+00:00

Add basic support for running directly on top of SBI, with no UEFI firmware present. Build as e.g.: make CROSS=riscv64-linux-gnu- bin-riscv64/ipxe.sbi The resulting binary can be tested in QEMU using e.g.: qemu-system-riscv64 -M virt -cpu max -serial stdio \ -kernel bin-riscv64/ipxe.sbi No drivers or executable binary formats are supported yet, but the unit test suite may be run successfully.

[riscv] Add support for the RISC-V CPU architecture

2024-09-15T21:34:10+00:00

Add support for building iPXE as a 64-bit or 32-bit RISC-V binary, for either UEFI or Linux userspace platforms. For example: # RISC-V 64-bit UEFI make CROSS=riscv64-linux-gnu- bin-riscv64-efi/ipxe.efi # RISC-V 32-bit UEFI make CROSS=riscv64-linux-gnu- bin-riscv32-efi/ipxe.efi # RISC-V 64-bit Linux make CROSS=riscv64-linux-gnu- bin-riscv64-linux/tests.linux qemu-riscv64 -L /usr/riscv64-linux-gnu/sys-root \ ./bin-riscv64-linux/tests.linux # RISC-V 32-bit Linux make CROSS=riscv64-linux-gnu- SYSROOT=/usr/riscv32-linux-gnu/sys-root \ bin-riscv32-linux/tests.linux qemu-riscv32 -L /usr/riscv32-linux-gnu/sys-root \ ./bin-riscv32-linux/tests.linux Signed-off-by: Michael Brown
