[v2 0/2] drm/msm/adreno: Reorganize firmware loading

[v2 0/2] drm/msm/adreno: Reorganize firmware loading

[Jordan Crouse]

This is new refresh of the outstanding changes from
https://patchwork.freedesktop.org/series/36923/.  Rob expressed concern about
the microcode code duplication per target so on his suggestions we did something
different.

The developer will specify a list of applicable microcode filenames per target.
Some semi-target specific enums are used to coordinate between the device
list and the driver code to figure out the position of the desired data
in the list.  This gets rid of the hardcoded struct members and makes it
flexible enough for future targets like a6xx to have their own unique list
of firmware names that don't match the past.

[PATCH 1/2] drm/msm/adreno: Define a list of firmware files to load per target

[Jordan Crouse]

The number and type of firmware files required differs for each
target. Instead of using a fixed struct member for each possible
firmware file use a generic list of files that should be loaded
on boot.  Use some semi-target specific enums to help each target
find the appropriate firmware(s) that it needs to load.

[PATCH 2/2] drm/msm/adreno: Use generic function to load firmware to a buffer object

[Jordan Crouse]

Move a5xx specific code to load firmware into a buffer object to
the generic Adreno code. This will come in useful for future targets.
