[U-Boot] [PATCH] pci: Treat all PCI bus addresses as 64-bit

[Wolfgang Denk]

Dear Kumar Gala,

I don't think this is a good idea. There are pure 32 bit systems  out
there which will never use more than 32 bit for the PCI resources, so
why load them with the additional memory size and execution time?

Should we not enable this only for such systems that actually need it?

Best regards,

Wolfgang Denk
