[Adrián Larumbe]

This is v3 for a previous patch series being discussed at:

https://lore.kernel.org/dri-devel/20220621023204.94179-1-adrian.larumbe@collabora.com/T/#t

Mesa MR under review can be found at:

Changes with respect to v2 of the same patch:

 - Added JS and MMU offset macros for selecting the right register in the dump rather
 than using magic numbers.
 - Added sanity check to make sure Panfrost's page size is the same as the CPU's
 - Added major and minor dump header version numbers
