Subject: [PATCH v3 0/4] add TOC support
Date: Thu, 14 Oct 2021 21:49:12 +0200	[thread overview]
Message-ID: <20211014194916.13901-1-svens@stackframe.org> (raw)

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 v3:
- add config option
- move toc code to its own c & .S file
- use early_initcall for setup
- split out struct declarations
- use sizeof(*ret) instead of sizeof(struct x)
- move virt_map to assembly.h so it can be used from other files

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

Sven Schnelle (4):
  parisc: move virt_map macro to assembly.h
  parisc: add PIM TOC data structures
  parisc/firmware: add functions to retrieve TOC data
  parisc: add support for TOC (transfer of control)
