[PATCH v3 30/46] boot: Avoid using the cmdline in bootmeth_pxe and pxe cmd

[Simon Glass]

Use the new netboot_run() function to avoid building a command line,
when running these network operations.

For the one board which uses lwip, it is not quite clear how to avoid
using the cmdline interface, so produce an error, for now. This can be
figured out later.
