The hw_info command is implemented to enable parsing Marvell hw_info formatted environments. This format is often used on Marvell Armada A37XX based devices to store parameters like the board serial number, factory MAC addresses and some other information. These parameters are usually written to the flash in the factory.
Currently the command supports reading/writing parameters and dumping the current hw_info parameters. EEPROM config pattern and checksum aren't supported.
This functionality has been tested on the GST ESPRESSOBin-Ultra board successfully, both reading the stock U-Boot parameters in mainline U-Boot and reading the parameters written by this command in the stock U-Boot.
Usage example: => hw_info load => saveenv
