| Subject | [PATCH 00/26] MIPS generic kernels, SEAD-3 & Boston support |

This series introduces some infrastructure for building generic kernels
which will run on multiple boards depending upon the device tree
provided to them by the bootloader. It converts SEAD-3 to make use of
this, and adds support for the MIPS Boston development platform.
The Boston support can be tested in QEMU with this patchset applied:
https://lists.gnu.org/archive/html/qemu-devel/2016-08/msg03419.html
To do so, configure the kernel for the generic 64r6el_defconfig & run
QEMU like so:
$ make ARCH=mips 64r6el_defconfig
$ make ARCH=mips CROSS_COMPILE=my-toolchain-
$ qemu-system-mips64el -M boston \
-kernel arch/mips/boot/vmlinux.gz.itb \
serial stdio
The same kernel binary will also boot on a SEAD-3 if using a bootloader
capable of loading the FIT image format (ie. U-Boot). These 2 boards
form the starting point for the generic kernels, with Ci20 & Ci40 able
to be added easily. Malta will require further work, but I've got most
peripherals converted to probe using device tree as a starting point &
will submit that separately.
This series applies atop v4.8-rc3 with my "MIPS: SEAD3 device tree
conversion" series applied first.
