10.1 EDK SP2, plbv46_pci_v1_02_a - The latest Tactical Patch "plbv46_pci_v1_03_a" fixes issues related to Linux booting on Ml510 system, Virtex-4 Q, Virtex-4 QR support and various other issues


The following are the latest "plbv46_pci_v1_03_a" fixes: 


- Fix for Virtex-5 to correct PCI BARs that were erroneously enabled when the parameter "C_PCIBAR_NUM" was less than 3. 

- Enhancement to increase PCI BAR length upper limit from 29 to 30 (power of 2) bytes. 

- Fix for SERR_N asserted during PCI2PLB read to allow prefetch to complete. 

- Moved to plbv46_slave_v1.01.b, not a functional difference. 

- Fix for Linux booting in ml510 where Linux/compiler optimization breaks up a configuration read 32-bit word operation into 4 separate byte read operations. The byte reads occurred quickly one after another and exposed an issue where the last byte read would be corrupt. 

- Added support for Virtex-4 Q and Virtex-4 QR.
