With some device trees (i.e. i.MX6 SoC) and longer REMOVE_PROPS list the fdtgrep tool stops with "Internal error with fdtgrep_find_regions()". Increase 'max_regions' count to avoid such errors.

Wow that's a lot. I wonder if we should adjust it to be unlimited?
I see the same issue for device-tree when number of pincontrol node > 100 in SPL (only see for debug use case).
But normally it is managed in the function (2 loops and re-alloc for the second loop if size > 100).
But the loop is not correctly managed, I think it is a issue introduced by Commit e178db1d7736a92951fdc7f1fd9b8ecf4d2877ba fdtgrep: Fix logic of free() in do_fdtgrep()
=> retrun -1 added for the 1rst loop.
I have locally a patch, but I don't yet upstream it.... It is done today with: "tools: ftdgrep: correct the find regions loop in do_fdtgrep" http://patchwork.ozlabs.org/project/uboot/list/?series=152371
Anatolij can you confirm that my patch correct also your issue ?

Patrick
