Module Name: src
Committed By: martin
Date: Thu Jan 9 16:23:42 UTC 2020
Modified Files:
src/sys/arch/aarch64/aarch64: cpu.c
src/sys/arch/arm/arm32: cpu.c
src/sys/dev/fdt: fdtbus.c
Log Message:
When attaching the first fdtbus, use the root "comptabile" (or failing that:
"model") property to set the cpu model (in userland aka sysctl hw.model).
When attaching the first cpu, do not overwrite a cpu model if it already
had been set.
