[U-Boot-Users] [PATCH] ColdFire: Added M5275EVB support.

> 1)  I can't save environment variables using saveenv.  I can change them just fine, and saveenv runs as usual, but on reset, I get a "*** Warning - bad CRC, using default environment "

I have the same problem. I haven't done any testing with the saveenv so
it more than likely needs some tweaking. The README mentions it quite a
bit so you may want to start there.

I use DHCP to get my IP address:
  -> setenv autoload no
  -> dhcp
  BOOTP broadcast 1
  DHCP client bound to address XXX.XXX.XXX.152
  -> ping XXX.XXX.XXX.189
  Using FEC0 device
  host XXX.XXX.XXX.189 is alive

However, if I try to ping the board I get a "Destination Host
Unreachable" error - apparently this is normal U-Boot behaviour.

I can also successfully use TFTP. 
  -> set serverip XXX.XXX.XXX.55
  -> tftpboot 20000 image.bin
  Using FEC0 device
  TFTP from server XXX.XXX.XXX.55; our IP address is XXX.XXX.XXX.152
  Filename 'image.bin'.
  Load address: 0x20000
  Loading:
  #################################################################
  done
  Bytes transferred = 1279856 (138770 hex)

I'm no real expert on this board/CPU so, other than sharing the commands 
I've used, I'm afraid I can't provide too much advice. I'm going to start
looking into the saveenv problem now.
