|
||||
* Patch by Lutz Dennig, 10 Apr 2003:
|
||||
Update for R360MPI board
|
||||
|
||||
* Add new meaning to "autostart" environment variable:
|
||||
If set to "no", a standalone image passed to the
|
||||
"bootm" command will be copied to the load address
|
||||
(and eventually uncompressed), but NOT be started.
|
||||
This can be used to load and uncompress arbitrary
|
||||
data.

||||
|
||||
* Patch by Stefan Roese, 10 Apr 2003:

packet. This fixes a problem using a Windows 2000 DHCP server,
|
||||
where the DHCP-server is not the TFTP-server.
|
||||
|
||||
* Set max brightness for MN11236 displays on TRAB board
|
||||
