A Massive ARM v6/v7 Rework Is Landing With Linux 4.5 Plus Raspberry Pi 2 Support
Olof Johansson sent in all of the ARM SoC updates for the Linux 4.5 merge window on Friday night. Most significant is the ARM multi-platform code update. Olof explained, "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts."
