or1k: add support for l.swa/l.lwa atomic instructions
This adds support for the load-link/store-conditional
l.lwa/l.swa atomic instructions.
The support is added in such way, that the cpu description not
only describes the mnemonics, but also the functionality.
A couple of fixes to typos in nearby/related code are also snuck
into this.
cpu/
* or1korbis.cpu (h-atomic-reserve): New hardware.
(h-atomic-address): Likewise.
(insn-opcode): Add opcodes for LWA and SWA.
(atomic-reserve): New operand.
(atomic-address): Likewise.
(l-lwa, l-swa): New instructions.
(l-lbs): Fix typo in comment.
(store-insn): Clear atomic reserve on store to atomic-address.
Fix register names in fmt field.
opcodes/
* or1k-desc.c: Regenerated.
* or1k-desc.h: Likewise.
* or1k-opc.c: Likewise.
* or1k-opc.h: Likewise.
* or1k-opinst.c: Likewise.
