2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-09-10riscv-trap-handling: Add implementation for trap calls in riscvThaminda Edirisooriya
RISCV requires the bios/bootloader to set up an interface by which it can get information about memory, talk to host devices, etc. Put implementation for spike in src/mainboard/emulation/spike-riscv/spike_util.c, and src/arch/riscv/trap_handler.c Change-Id: Ie1d5f361595e48fa6cc1fac25485ad623ecdc717 Signed-off-by: Thaminda Edirisooriya <thaminda@google.com> Reviewed-on: http://review.coreboot.org/11368 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2015-08-09riscv-spike: support for Spike emulation of riscvThaminda Edirisooriya
Spike support: QEMU RISCV is broken, and the maintainers at Berkeley are working on it, but at the moment spike is the only way to test on riscv. Add support for spike console output for debugging. Privileged ISA: Update to privileged ISA in RISCV (machine, supervisor, hypervisor, user modes) broke exisitng RISCV asm, and bootblock.S was updated to match the new spec. Clean old assembly [pg: things build with gcc 4.9 now, but don't expect them to work. Hardcoding register names into the assembler language may not be the smartest idea of the RISCV folks.] Change-Id: Ie2c109d3c26712c207512f74f28ce1a925e6e181 Signed-off-by: Thaminda Edirisooriya <thaminda@google.com> Reviewed-on: http://review.coreboot.org/11078 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
