[PATCH v2 1/3] cmd: mvebu: Implement the Marvell hw_info command

[Marek Behun]

Luka, Tom,

I am very against this.

there already is `mac` command in cmd/mac.c with following help
   display and program the system ID and MAC addresses in EEPROM
   [read|save|id|num|errata|date|ports|port_number]
   mac read
       - read EEPROM content into memory data structure
   mac save
       - save memory data structure to the EEPROM
   mac id
       - program system id per hard coded value
   mac num string
       - program system serial number to value string
   mac errata string
       - program errata data to value string
   mac date YYMMDDhhmmss
       - program date to string value YYMMDDhhmmss
   mac ports N
       - program the number of network ports to integer N
   mac X string
       - program MAC addr for port X [X=0,1..] to colon separated string"

Why introducing new, vendor specific commands, when we have a global
API for such a thing?
