Hi Gary,

The size returned by 'getvar partition-size' should be in bytes, not in blocks as fastboot uses that value to generate empty partition when running format [1].

Note that the function was already returning the proper size in bytes for NAND devices (see struct part_info details).

Thank you for the patch, all look good! As I understand from the changelog, v2 fixes sunxi build error found by Lukasz? Other than that:

Changelog v1->v2:

• removed change for FASTBOOT_FLASH_NAND as not necessary (and therefore not building)
