FreeBSD and Coreboot

I have approx. 130 of the PC Engines APUs in varius
versions up until the most recent, running with FreeBSD just fine.

No special setup, just the generic coreboot firmware.
Well, they had some issues with 12.0-REL booting from USB sticks
Booting 11.2 sticks, installing and upgrading works fine.
Did not test more recent firmware.

This worked to reflash the BIOS to their most recent versions:

Source of the BIOS:

I used 

flashrom -w apu4_v4.9.0.5.rom  --programmer internal

to upgrade:

Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) mapped at physical address 0x00000000ff800000.

/usr/local/bin/flashrom was installed by package flashrom-1.0_1
