This is the Mesa and DRM driver for Broadcom VC4 hardware. It is notably used in the Raspberry Pi and Raspberry Pi 2 hardware. The addition is very simple and applies to all ebuilds from mesa-10.3.7-r1.ebuild and newer.

Just add "gallium_enable video_cards_vc4 vc4" to the section of each ebuild from version 10.3.7-r1 onward in the section near the other gallium_enable calls.
The vc4 driver requires a kernel driver that is not yet upstream and the developer does not want the vc4 driver shipped in distributions yet because it might mean he's locked into an unfinished kernel ABI. WONTFIX for now.
Created attachment 430360 [details, diff] Enable vc4 in all current versions Enable VC4 support in all versions and bump revision
I am reopening this due to the following reasons: - The VC4 driver is in upstream 4.5 now. - The Raspberry Pi Foundation's kernel tree now includes the driver in the current rpi-update 4.1 branch, and also the 4.5 branch. - For 64bit builds both Zeldins and Electron752 forks include the driver. - VC4 support is included as an option in the 2016-02-09 Rasbpian release.
