HI,

this is just a heads up: the handling of multi-line environment variables is broken in recent versions of U-Boot (and probably has been broken for some longer time - can't tell exactly as I have a bit of a problem to bisect across the MAKEALL / Kconfig changes):

Test case:

• Set multi-line var:

    => setenv foo 'echo line 1
    > echo line 2
    > echo line 3'
  
  

  OK

• Print multi-line var:

    => print foo
    foo=echo line 1
    echo line 2
    echo line 3
  
  

  OK

• Run multi-line var:

    => run foo
    line 1
  
  

  ERROR. Only the first line gets executed, the rest is missing. Only the first line gets parded by the hush shell...
