From: Rob Herring <robh@xxxxxxxxxx> This series adds support for early serial console initialization using DT. This enables determining the serial port type and address using the FDT and allows enabling the console before platform specific initialization runs. I've tested this on arm64. ARM support is dependent on adding fixmap support. Currently, the earlycon is only enabled if "earlycon" is present on the kernel command line. The FDT needs to have /chosen/stdout-path set to the path of the serial port. This series is dependent on generic earlycon[1], libfdt support[2], and vmlinux.lds.h clean-ups[3]. The first 2 are in linux-next already.
