[mesa] Enable Radeon support

[eibach]

Radeon support is disabled in the Pkgbuild. Since I have a Radeon card in my system, I would really like to have it enabled by default.

You have a Radeon card, in your ARM SoC system?

[eibach]

Sure, works extremely well. There is some fixes in u-boot and the amdgpu-driver to make this work.

I think Warheads is asking what your machine is ...

[eibach]

My machines are Macchiatobin and Marvell Armada 8040 DB.

Interesting - I've not seen a arm machine with a PCIe slot! So you have a Radeon card in the PCIex4 slot?

From the hardware, yes that seems a viable configuration. But actually i'm not surprised that it isn't enabled by default on ArchLinux Arm. Most arm cpu come with gpu on board, and thats usually a VR, mali, or the like. The arm cpu are set up for mobile phones. But in the case of the ARMADA 8040 - it seems a very different device.

Guess some thinking will be needed. Do other PCIe devices work? e.g. is the PCIe in the Arm kernel?

The Marvell Armada and NXP Quoriq series come from a totally different background. They have a server/networking background and have very performant peripherals. PCIe is fully implemented. The 8040DB has six slots and all kinds of cards I tried (network, raid, ...) work nicely.
