Subject: PCI: designware: Fix RC BAR to be single 64-bit non-prefetchable
memory BAR
From: Mohit Kumar <[email protected]>
commit dbffdd6862e67d60703f2df66c558bf448f81d6e upstream.
The Synopsys PCIe core provides one pair of 32-bit BARs (BAR 0 and BAR 1).
The BARs can be configured as follows:
- One 64-bit BAR: BARs 0 and 1 are combined to form a single 64-bit BAR
- Two 32-bit BARs: BARs 0 and 1 are two independent 32-bit BARs
This patch corrects 64-bit, non-prefetchable memory BAR configuration
implemented in dw driver.
