Up till now the CRC32 of received data was calculated unconditionally. The standard crc32 implementation causes long delay when large images were uploaded.
The "dfu_hash_algo" environment variable gives the opportunity to enable on demand (when e.g. debugging) the hash (crc32) calculation. It can be done without need to recompile the u-boot binary and reuses the generic hash framework.
By default the crc32 is NOT calculated anymore.
Tests results: 400 MiB ums.img file With crc32 calculation: 65 sec [avg 6.29 MB/s] Without crc32 calculation: 25 sec [avg 16.17 MB/s]
