When initializing the i915, we want to be sure that the PCI
BARs have been properly initialized.
As part of this series, I have prepared two patches,
one that introduces BARs names to use in code instead of numbers,
and another that adds function to validate BARs before use
From: Piotr Piórkowski
For proper operation of i915 we need usable PCI GTTMMADDR BAR 0
(1 for GEN2). In most cases we also need usable PCI GFXMEM BAR 2.
Let's add functions to check if BARs are set, and that it have
a size greater than 0.
In case GTTMMADDR BAR, let's validate at the beginning of
From: Piotr Piórkowski
At the moment, when we refer to some PCI BAR we use the number of
this BAR in the code. The meaning of BARs between different platforms
may be different. Therefore, in order to organize the code,
let's start using defined names instead of numbers.
