The CRC32 is not collision-proof in similar fashion that SHA1. In real life, if two binary images give the same SHA1 checksum, you can say that these binaries are identical. With CRC32 this is not so - or at least I would not count on that :-)
Well, normally you have additional information like the U-Boot image header, version id, etc.
But feel free to implement sha1 support - if it can be configured cleanly away then it's fine...
