[U-Boot] [PATCH 00/12] Introduce layout aware eeprom commands

[Nikita Kiryanov]

This series introduces eeprom layout aware capabilities to the existing eeprom
command, and then enables this feature on Compulab boards. It is an import of
the Compulab eeprom-utility (https://github.com/compulab/eeprom-util), and it
introduces 2 new options to the eeprom command:

eeprom print [-l <layout_version>] bus_num device_addr
eeprom update [-l <layout_version>] bus_num device_addr <field_name> <field_value>

The series starts with importing the code in a way that is very separated from
the existing eeprom command code (it uses its own parsing function and its own
command execution code, but does reuse the eeprom_read and eeprom_write
functions), then activates the feature for all Compulab boards, and finally
merges the layout aware code with the layout unaware code so that there is one
parsing function, and one command execution function.

Features:
- print EEPROM layout in a human readable way (field names and formatted data)
- update EEPROM data by specifying the field name and the new data in a human
  readable format (same format as shown by the print command)
- Layout can be either auto detected, or manually selected with the -l option
- Completely optional and backwards compatible with current eeprom command

Tested on cm-t43 and cm-fx6. Final result compile tested on arm.

Example of use:
