The configuration for the AMCC 440EP eval board "Bamboo" was changed
to only use 384 kbytes of FLASH for the U-Boot image. This way the
redundant environment can be saved in the remaining 2 sectors of the
same flash chip.
Caution: With an upgrade from an earlier U-Boot version the current
environment will be erased since the environment is now saved in
different sectors. By using the following command the environment can
be saved after upgrading the U-Boot image and *before* resetting the
board:
setenv recover_env 'prot off FFF80000 FFF9FFFF;era FFF80000 FFF9FFFF;' \
'cp.b FFF60000 FFF80000 20000'
