2019-02-13riscv: Add initial support for 32bit boardsPhilipp Hug
* Adding separate targets for 32bit and 64bit qemu * Using the riscv64 toolchain for 32bit builds requires setting -m elf32lriscv * rv32/rv64 is currently configured with ARCH_RISCV_RV32/RV64 and not per stage. This should probably be changed later. TEST=Boots to "Payload not loaded." on 32bit qemu using the following commands: util/riscv/make-spike-elf.sh build/coreboot.rom build/coreboot.elf qemu-system-riscv32 -M virt -m 1024M -nographic -kernel build/coreboot.elf Change-Id: I35e59b459d1770df10b51fe9e77dcc474d7c75a0 Signed-off-by: Philipp Hug <philipp@hug.cx> Reviewed-on: https://review.coreboot.org/c/31253 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: ron minnich <rminnich@gmail.com>

2019-02-11device/pci_ops: Move questionable pci_locate() variantsKyösti Mälkki
These are defined for __SIMPLE_DEVICE__ when PCI enumeration has not happened yet. These should not really try to probe devices other than those on bus 0. It's hard to track but there maybe cases of southbridge being located on bus 2 and available for configuration, so I rather leave the code unchanged. Just move these out of arch/io.h because they cause build failures if one attempts to include <arch/pci_ops.h> before <arch/io.h>. There are two direct copies for ROMCC bootblocks to avoid inlining them elsewhere.

2018-12-30arch/x86: Prevent romcc bootblock from using MMX registersKyösti Mälkki
Platforms with SSE=y or SSE2=y will invoke romcc with -mcpu=k7. This implicitly enabled romcc to consume MMX registers, if XMM set was consumed first. Explicitly tell romcc not to clobber MMX set.

This patch introduces 3 helper function for cpuid(1) : 1. cpu_get_cpuid() -> to get processor id (from cpuid.eax) 2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx) 3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx) Above 3 helper functions are targeted to replace majority of cpuid(1) references.
