The last version with the ARM bits is here[1]. I've added fixmap permanent mappings support to this series in order to support generic earlycon on ARM. This enables early console output before any machine hooks run and is configurable on the command line unlike earlyprintk. This is based on the tty-next tree which has the generic earlycon support for 3.16. A git tree is available here[2].
