Draft: NASA EEFS support

Dmitry Petrov requested to merge eefs-support into guf_imx_v2020.04-trizeps8plus_2021_12_07

Based on EEFS 2.0 release. Commit 409867bcbca2f0e5b549ea38426d827cc6d44152

https://github.com/nasa/eefs/releases/tag/eefs-2.0

Only read mode is supported at the moment. The whole EEPROM is loaded into memory at the initialization step.

Available U-boot commands:

  • eefsls — show list of files
  • eefssize <filename> — get size of file and save it to filesize environment variable
  • eefsload <filename> <addr> — load file <filename> into memory at the <addr> and set two environment variables: fileaddr and filesize.
