[U-Boot] Atheros "ART" data crc calculation

[Dmytro]

Hello again Allan,
Can you on work device (with correct ART section and with no checksum
error), enter the u-boot command - "printenv" ?
Also would you please share your ART section of the same device?

Idea is this, it is necessary to calculate the checksum of ART section
(only not clearly what part of the calculate, with empty sectors "FF"
or workspace) in CRC32 format, then correct this checksum in "buf_crc"
environment variable.
