Hi,
thanks for your patch Hatim! I have fixed some minor problems and
repost the patch in case you want to edit it further (e.g. to change
the test status if need be ;).
This patch and also some of the previous ones had some white space
errors that we missed in the last review. Please keep a closer look
at the use and numbers of tabs and spaces in flashchips.c. This is
also important because we need to edit the file automatically in the
future when introducing the new probing architecture and any
irregularities might complicate things then. I have fixed the unrelated
problems in my tested stuff branch.
