Hi Adam,
Partial reads are not currently supported in upstream (even with a layout
file), but they are supported in the ChromiumOS branch:
https://chromium.googlesource.com/chromiumos/third_party/flashrom
Basically what you'll need to do is:
1. Make sure your chip is supported (in flashchips.c).
2. Create a layout file ('echo "start:end name" >> layout.txt')
3. flashrom -p dediprog -r -l layout.txt -i name:name.bin
For example, if your start and end are 000:fff and the name is "bottom_4k",
the command `flashrom -p dediprog -r -l layout.txt -i
bottom_4k:bottom_4k.bin` will read 4K from 0x000000-0x000fff and write it
to a file called bottom_4k.bin.
HTH!
