wdenk6bd14892003-04-10 11:18:18 +00002Changes since U-Boot 0.3.0:
3======================================================================
4
wdenk92bbe3f2003-04-20 14:04:18 +00005* Make sure Block Lock Bits get cleared in R360MPI flash driver
6
7* MPC823 LCD driver: Fill color map backwards, to allow for steady
8 display when Linux takes over
9
10* Patch by Erwin Rol, 27 Feb 2003:
11 Add support for RTEMS (this time for real).
12
13* Add support for "bmp info" and "bmp display" commands to load
14 bitmap images; this can be used (for example in a "preboot"
15 command) to display a splash screen very quickly after poweron.
16
17* Add support for 133 MHz clock on INCA-IP board
18
wdenk3f9ab982003-04-12 23:38:12 +000019* Patch by Lutz Dennig, 10 Apr 2003:
20 Update for R360MPI board
21
22* Add new meaning to "autostart" environment variable:
23 If set to "no", a standalone image passed to the
24 "bootm" command will be copied to the load address
25 (and eventually uncompressed), but NOT be started.
26 This can be used to load and uncompress arbitrary
27 data.
28
stroeseee14b832003-04-10 13:30:28 +000029* Patch by Stefan Roese, 10 Apr 2003:
wdenk3f9ab982003-04-12 23:38:12 +000030 Changed DHCP client to use IP address from server option field #54
31 from the OFFER packet in the server option field #54 in the REQUEST
32 packet. This fixes a problem using a Windows 2000 DHCP server,
33 where the DHCP-server is not the TFTP-server.
34
35* Set max brightness for MN11236 displays on TRAB board

wdenk2582f6b2002-11-11 21:14:20 +0000408* Patch by Jim Sandoz, 07 Nov 2002:
409 Increase number of network RX buffers (PKTBUFSRX in
410 "include/net.h") for EEPRO100 based boards (especially SP8240)
411 which showed "Receiver is not ready" errors when U-Boot was
412 processing the receive buffers slower than the network controller
413 was filling them.

416 Change behaviour of NetLoop(): return -1 for errors, filesize
417 otherwise; return code 0 is valid an means no file loaded - in this
418 case the environment still gets updated!
