a73b93157f tree: drop last paragraph of GPL copyright header
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.

d9653e1328 riscv-trap-handling: Add functionality, prevent stack corruption
Trap handling code was bugged in that it loaded in the wrong stack
pointer, overwriting the space the processor uses to talk to its host
for doing device requests. Fix this issue, as well as add support for
handling misaligned loads the same way we handle misaligned stores.

95ba4c87f5 riscv-trap-handling: Add implementation for trap calls in riscv
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
