[MinnowBoard] [Minnowboard Max] - Way to reset BIOS settings? (No USB)

[John Hawley]

In the normal case, not long minute or two.

Full erase:
	# time ./flashrom -p \
		ft2232_spi:type=2232h,port=A,divisor=4 \
		--erase
	flashrom v0.9.8-r1889 on Linux 4.1.6-200.fc22.x86_64 (x86_64)
	flashrom is free software, get the source code at
	http://www.flashrom.org

	Calibrating delay loop... OK.
	Found Micron/Numonyx/ST flash chip "N25Q064..1E" (8192 kB, SPI)
	on ft2232_spi.
	Erasing and writing flash chip... Erase/write done.

	real    9m16.173s
	user    8m3.940s
	sys     0m2.175s

Full write:

	# time ./flashrom -p ft2232_spi:type=2232h,port=A,divisor=4 \
		-w firmware-minnow/MNW2MAX1.X64.0082.R01.1507081055.bin
	flashrom v0.9.8-r1889 on Linux 4.1.6-200.fc22.x86_64 (x86_64)
	flashrom is free software, get the source code at
	http://www.flashrom.org

	Calibrating delay loop... OK.
	Found Micron/Numonyx/ST flash chip "N25Q064..1E" (8192 kB, SPI)
	on ft2232_spi.
	Reading old flash chip contents... done.
	Erasing and writing flash chip... Erase/write done.
	Verifying flash... VERIFIED.

	real    2m54.493s
	user    0m4.246s
	sys     0m3.733s

Your mileage is going to vary, and this is a lot slower than some other
hardware, but on the flip side this is one of the cheapest SPI
programmers I know of, as well as also being an FTDI serial cable.
