Author: Iago Toral Quiroga <[email protected]> Date: Thu Feb 11 11:52:13 2021 +0100 broadcom/compiler: don't check for GFXH-1633 on V3D 4.2.x This has been fixed since V3D 4.2.14 (Rpi4), which is the hardware we are targetting. Our version resolution doesn't allow us to check for 4.2 versions lower than .14, but that is okay because the simulator would still validate this in any case.
