Add support to flashrom for Hyundai HY29F002T on the assumption it is the same as other *29F002T chips. Running 'flashrom -r' finds the chip and reads what looks like a BIOS image, other than that it is un-tested.

Once I de-solder these chips and get some sockets fitted I can do some proper testing! Gigabyte GA-7ZXR has two of them for its DualBIOS™. Switching between chips seems to be done in software... Very useful.

Gigabyte owns a patent involving a timer and a software handshake.

Interesting... That software has to be stored somewhere though, right? Unless there is a third ROM, it'll have to be within both BIOSes...

The handshake only needs to be in one BIOS. If the handshake is not performed within some time period, the board is reset, the other flash chip activated, and then the CPU is taken out of reset. The second BIOS image needs no handshake.
