when uplaoding a file, at least from a nand partition, the complete mtd nand partition size is transferred. This leads in a wrong md5sum as the filesize is different between the downloaded file and the uploaded file. Limit the uploaded filesize to the downloaded fixes this.
I was going to say that it'd be better to fix U-Boot's NAND code to transfer the correct amount of data. However, I suppose the correct amount *is* the whole partition for anything other than a filesystem file. As such, I'd suggest replacing "nand" in the patch description with something else, since presumably the exact same issue applies to partitions on eMMC. The issue applies to any partition.
I wonder if there's a way to distinguish between file tests and partition tests in dfu_gadget_test.sh, so that the $N_FILE_FULL -> $N_FILE conversion can be applied only for partitions. Otherwise, a file upload/download test could end up changing (increasing) the file length and this bug wouldn't be detected.
