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