PS31: 
Has anyone managed to get internal flashing to work on the 7020/9020/XE2? flashrom only sees 8 MB of the total 12 for me. I tried `flashrom -p internal:ich_spi_mode=hwseq` as suggested by Máté but no dice. Here's what I get with that parameter:

```
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Opened /dev/mtd0 successfully
Unhandled programmer parameters: ich_spi_mode=hwseq
Aborting.
Error: Programmer initialization failed.
```
