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].

Signed-off-by: Gary Bisson gary.bisson@boundarydevices.com --- Hi,
Another test was to run 'fastboot getvar partition-size:system' on a shipping Android phone, it will give you the size in bytes as well.
