2016-06-12riscv-spike: Replace custom UART with a memory-mapped 8250Jonathan Neuschäfer
Since the HTIF is a non-standard interface, and coreboot already has a 8250 driver, I started implementing an 8250 core for spike[1].

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.

2015-08-09riscv-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>
