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. v3 drops some patches which aren't critical & need comments made during review addressing. This series applies atop mips-for-linux-next as of 6a44eb2884ca, but needs the remaining patches of my SEAD-3 DT conversion series to be applied first.
