Subject: dfu: remove limitation on partition size
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=15970d871c299c8a4218911ee68edb0495a69cd4;p=u-boot.git

dfu: remove limitation on partition size

Change long (32 bits on arm) to u64 (same type than offset)
for size and read offset r_left

So partition and device used for DFU can be greater than 4GB
