TIAO/DIYGADGET USB Multi-Protocol Adapter (TUMPA) support
Thanks to TIAO/DIYGADGET for sponsoring a test device!
This is an FTDI FT2232H based device which provides an easily accessible JTAG,
SPI, I2C, serial breakout. The SPI part can be used to flash SPI flash chips
using flashrom.

There are two SPI connectors (pin headers) on the board: SPI1, which is
connected to the FT2232H's A interface, and SPI2, which is connected to the
chip's B interface. Both can be used to flash SPI chips:
flashrom -p ft2232_spi:type=tumpa,port=A
flashrom -p ft2232_spi:type=tumpa,port=B
The default interface is A, so for SPI1 you can also just write:
flashrom -p ft2232_spi:type=tumpa
I tested all operations on both interfaces, everything works fine.
Corresponding to flashrom svn r1451.
