This adds support for the TOC switches found on most PA-RISC
machines. I tested this on my c8000 and a HP 16702A, which is
basically a B160L with some logic analyzer hardware.

Changes in v2:
- fix stack allocation
- align toc_lock on 16 byte boundary
- move toc_lock declaration to processor.c

Sven Schnelle (2):
  parisc/firmware: add functions to retrieve TOC data
  parisc: add support for TOC (transfer of control)
