There's also a couple of hardcoded tables for a couple of very specific
configurations that NVGPU's algorithm didn't work for.

The algorithm for GM200 and newer matches RM for all the boards I have, but
I don't have enough data to try and figure something out for earlier boards,
so these will still write zeroes to the table as we did before.

The code in NVGPU isn't helpful here, it appears to handle specific cases.

I haven't yet been able to find a fully programatic way of calculating the
same mapping as NVIDIA for GF100-GF119, so the algorithm partially depends
on data tables for specific configurations.

I couldn't find traces for every possibility, so the algorithm will switch
to a mapping similar to what GK104-GM10x use if it encounters one.  We did
the wrong thing before anyway, so shouldn't matter too much.

The algorithm used in the GK104 implementation was ported from NVGPU.

Deliberately removed from non-GP100, as RM doesn't touch it.

We need to be able to prevent memory from being freed while it's still
mapped in a GPU's address-space.

Will be used by upcoming MMU changes.

Map flags (access, kind, etc) are currently defined in either the VMA,
or the memory object, which turns out to not be ideal for things like
suballocated buffers, etc.

These will become per-map flags instead, so we need to support passing
these arguments in nvkm_memory_map().

Change the secboot and msgqueue interfaces to take a mask of falcons to
reset instead of a single falcon. The GP10B firmware interface requires
FECS and GPCCS to be booted in a single firmware command.

For firmwares that only support single falcon boot, it is trivial to
loop over the mask and boot each falcons individually.

Reading registers at device construction time can be harmful, as there
is no guarantee the underlying engine will be up, or in its runtime
configuration. Defer register reading to the oneinit() hook and update
users accordingly.
