adf64e2142 drm/amd: Avoid reading the VBIOS part number twice
The VBIOS part number is read both in amdgpu_atom_parse() as well
as in atom_get_vbios_pn() and stored twice in the `struct atom_context`
structure. Remove the first unnecessary read and move the `pr_info`
line from that read into the second.

v2: squash in unused variable removal

29b4c589b4 drm/amdgpu: Add vbios info ioctl interface
Add AMDGPU_INFO_VBIOS_INFO subquery id for detailed vbios info.

Provides a way for the user application to get the VBIOS
information without having to parse the binary.
It is useful for the user to be able to display in a simple way the VBIOS
version in their system if they happen to encounter an issue.

V2:
Use numeric serial.
Parse and expose vbios version string.

V3:
Remove redundant data in drm_amdgpu_info_vbios struct.

V4:
64 bit alignment in drm_amdgpu_info_vbios.

v5: squash together all the reverts, etc. (Alex)

e99d2eaafd drm/amdgpu: drop legacy IO bar support
It was leftover from radeon where it was required for some
specific old hardware.  It hasn't been required for ages
and the driver already falls back to MMIO when legacy IO
is not available.  Legacy IO also seems to be problematic on
on some thunderbolt devices.  Drop it.

db95e21855 drm/amdgpu: Add debugfs file for VBIOS and version
Add 2 debugfs files, one that contains the VBIOS version, and one that
contains the VBIOS itself. These won't change after initialization,
so we can add the VBIOS version when we parse the atombios information.

This ensures that we can find out the VBIOS version, even when the dmesg
buffer fills up, and makes it easier to associate which VBIOS version is
for which GPU on mGPU configurations. Set the size to 20 characters in
case of some weird VBIOS version that exceeds the expected 17 character
format (3-8-3\0). The VBIOS dump also allows for easy debugging

    v2: Move to debugfs, clarify commit message, add VBIOS dump file
