BugLink: https://bugs.launchpad.net/bugs/2026776

SRU Justification:

[ Impact ]

On systems that have the following combination of hardware

1) arm64 CPU
2) ASPEED AST2600 BMC: https://www.aspeedtech.com/server_ast2600/

No output when connecting a display to the BMC's VGA port.

[ Fix ]

For AST2500+ MMIO should be enabled by default.

[ Test Plan ]

Test on targeted hardware to make sure BMC is displaying output.

[ Where problems could occur ]

Not aware of any potential problems, but any should be confined to
ASPEED AST2500+ hardware.

[ Other Info ]

Patch is already in jammy/nvidia-5.19 and jammy/nvidia-6.2 and has been tested with
affected BMC.
