[Qemu-devel] [PULL v2 00/52] target-arm queue

From: Peter Maydell
Subject: [Qemu-devel] [PULL v2 00/52] target-arm queue
Date: Fri, 24 Aug 2018 13:28:51 +0100

target-arm queue: this clears out a bunch of patches I'd sent over
the last coupled of weeks that have now got reviewed. Mostly
this is MPS2 device support improvements, put there is also
more of the incremental work towards supporting AArch32 Hyp mode,
a floating point bugfix, and the raspi framebuffer viewport support.

v2 fixes a "variable used uninitialized" error in a15mpcore.c.

  hw/arm/mps2: Fix ID register errors on AN511 and AN385 (2018-08-24 13:17:50 

target-arm queue:
 * Fix rounding errors in scaling float-to-int and int-to-float operations
 * Connect virtualization-related IRQs and memory regions of GICv2
   in boards that use Cortex-A7 or Cortex-A15
 * Support taking exceptions to AArch32 Hyp mode
 * Clear CPSR.IL and CPSR.J on 32-bit exception entry
   (a minor bug fix that won't affect non-buggy guest code)
 * mps2-an505: Implement various missing devices:
   dual timer, watchdogs, counters in the FPGAIO registers,
   some missing ID/control registers, TrustZone Master Security
   Controllers, PL081 DMA controllers, PL022 SPI controllers
 * correct ID register values for mps2-an385, -an511, -an505
 * fix some hardcoded tabs in untouched backwaters of the
   target/arm codebase
 * raspi: Refactor framebuffer property handling code and implement
   support for the virtual framebuffer/viewport
