Hi Fred,

I think you can't update this file directly. Pulling the Linux mach-types
file is the ARM maintainer job.

Note that for the CloudBox board, the mach-types entry has been removed
because not needed by Linux. The Linux mainline support is only based on
DT. I had the same issue with the ns2 lite and mini. At the time, I have
been told to include the machine ID in the board header:
http://marc.info/?l=u-boot&m=134694402011372&w=2

Looks in configs/lacie_kw.h and grep for "missing in mach-types.h".

Besides, I don't understand why do you need a separate patch to add the
legacy boot support.

Simon
