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@lists.denx.de but I don't see it
in the mailing list (possibly because I botched the commit message).
