Module Name: src
Committed By: jmcneill

Modified Files:
src/sys/arch/arm/fdt: arm_fdt.c arm_fdtvar.h gtmr_fdt.c
src/sys/arch/evbarm/tegra: tegra_start.S
Log Message:
Allow ARM FDT drivers to register per-cpu init callbacks. Run through this
callback list when a CPU hatches instead of calling gtmr_init_cpu_clock
directly.
