[U-Boot] uboot pci enumeration

[Vinay Venkataraghavan]

Hello everybody,

Really quick and hopefully easy question:

Does uboot do PCI enumeration in common code or is this task left to the individual board specific code and setup tasks.?

Thanks a lot in advance!!

[U-Boot] [PATCH] part_efi: Fix partition size calculation due to inclusive ending LBA.

[Richard Retanubun]

This patch fixed an off-by-one bug found for GPT. Because the ending LBA is inclusive, 
the partition size should be ((ending_lba + 1) - starting-LBA).

This is confirmed against the results from the parted tool.
(e.g. use parted /dev/sda -s unit S print) and observe the size.

Hi Wolfgang,

I sent this patch in december 12 to u-boot at lists.denx.de but I don't see it 
in the mailing list (possibly because I botched the commit message).
