Dear Stefano Babic,

BMODE command? How does that one work?
It sets for i.MX (MX5/MX6) from which source the BootROM must read the image. We can say it is a soft way to overwrite the boot pin configuration without having to write into fuses, useful to test different boot conditions.
Seems to be the same thing ... or similar at least.

Can you reorder the list ?
How? It's out of order already.
I know - it would be nice if the list was in order again, at least for the components of mkimage (NOPED_OBJ_FILES-).
I will do a separate patch.

Comparing this polinomial with the one in lib/crc32.c, they are identical. The crc32 function you define here should give the same result as our old crc32 (global) in lib/crc32.c. Then, can you drop this one and use the already implemented function ?
As I do not want to diverge more than necessary, this can be done in subsequent patch.
However this adds a duplication in the code, and using the global crc should be quite straightforward.
We cannot use the zlib crc32 function which is implemented in lib/crc32.c as the CRC32 used by MXS bootrom uses bit-flipped polynomial compared to the zlib implementation.
