Subject: [PATCH v2 00/10] MIPS: Add virtual Ranchu board as a generic-based board
From: Aleksandar Markovic <aleksandar.markovic@...tec.com>
v1->v2:
- patch on RTC driver cleaned up
- added drivers for virtio console and net to the Ranchu board
- minor improvements in commit messages
- updated recipient lists using get_maintainer.pl
- rebased to the latest code
This series adds Mips Ranchu virtual machine used by Android emulator.
The board relies on the concept of Mips generic boards, and utilizes
generic board framework for build and device organization.
The Ranchu board is intended to be used by Android emulator.The name
"Ranchu" originates from Android development community. "Goldfish" and
"Ranchu" are names for two generations of virtual boards used by
Android emulator. "Ranchu" is a newer one among the two, and this
series deals with Ranchu. However, for historical reasons, some file,
device, and variable names in this series still contain the word
"Goldfish".
Mips Ranchu machine includes a number of Goldfish devices. The
support for Virtio devices is also included. Ranchu board supports
up to 16 virtio devices which can be attached using virtio MMIO Bus.
This is summarized in the following picture:

|| | (virtio-net)------------------
Device Tree is created on the QEMU side based on the information about
devices IO map and IRQ numbers. Kernel will load this DTB using UHI
boot protocol.
Checkpatch script outputs a small number of warnings if applied to
this series. We did not correct the code, since we think the code is
correct for those particular cases of checkpatch warnings.
