[PATCH v2 0/3] Improve MIPS Magnum support

[PATCH v2 0/3] Improve MIPS Magnum support

[Finn Thain]

A few minor patches are needed to more easily boot a MIPS Magnum build
under QEMU. This series fixes a build failure in the g364fb driver and
modifies jazz_defconfig for use with 'qemu-system-mips64el -M magnum'.

Note that QEMU's dp8393x implementation has bugs, one of which prevents
the Linux jazzsonic driver from probing the chip. I have fixed the bugs
that I know of in a series of patches at,
https://github.com/fthain/qemu/commits/sonic

Changed since v1:
 - Added reviewed-by and tested-by tags from Philippe Mathieu-Daudé.
 - Rebased.


Finn Thain (3):
  fbdev/g364fb: Fix build failure
  mips/jazz: Remove redundant settings and shrink jazz_defconfig
  mips/jazz: Update jazz_defconfig for MIPS Magnum

[PATCH v2 1/3] fbdev/g364fb: Fix build failure

[Finn Thain]

This patch resolves these compiler errors and warnings --

The MIPS Magnum framebuffer console now works when tested in QEMU.
