[Qemu-devel] [PATCH v2 00/11] v8m: minor missing regs and bugfixes

From: Peter Maydell
Subject: [Qemu-devel] [PATCH v2 00/11] v8m: minor missing regs and bugfixes
Date: Fri, 9 Feb 2018 16:57:59 +0000

This patchset is the result of comparing the registers
listed in the v8M Arm ARM against what QEMU was implementing.
It adds a collection of generally unexciting missing registers
(most of which we can simply NOP or make reads-as-written).
There are also a couple of bug fixes in there, of which the
worst is the byte-to-interrupt-number conversions being
completely wrong in several places.

Version 2 adds 3 new patches at the end:
 * we had a couple of things we were forgetting to migrate
 * implementation of MSPLIM and PSPLIM, which were the missing
   special registers

I've updated the cache ID registers patch to use some constants
for register bit fields; otherwise the first 8 patches are the
same as v1. The derived-exceptions patches are in master now,
so this should apply to master.
