|
||||
|
||||
* Add support for Promess ATC board
|
||||
|
||||
* Patch by Keith Outwater, 28 Apr 2003:
|
||||
- Miscellaneous corrections and additions to GEN860T board specific code.
|
||||
- Added GEN860_SC variant to GEN860T.
|
||||
- Miscellaneous corrections to GEN860T documentation.
|
||||
- Correct duplicate entry in U-Boot CREDITS file.
|
||||
- Add GEN860T_SC entry in MAINTAINERS file.
|
||||
- Update CREDITS file with GEN860T_SC info.
|
||||
|
||||
* Update Smiths Aerospace addresses in MAINTAINERS file
|
||||
|
||||
* Fix error handling in hush's version of "run" command
|
||||
|
||||
* LWMON extensions:
|
||||
- Splashscreen support
|
||||
- modem support
|
||||
- sysmon support
|
||||
- temperature dependend enabling of LCD
|
||||
|
||||
* Allow booting from old "PPCBoot" disk partitions
|
||||
|
||||
* Add support for TQM8255 Board / MPC8255 CPU
|
||||
|
||||
======================================================================
|
||||
Changes for U-Boot 0.3.1:
|
||||
======================================================================
|
||||
|
||||
* Make sure Block Lock Bits get cleared in R360MPI flash driver
|
||||
|
||||
* MPC823 LCD driver: Fill color map backwards, to allow for steady
|
||||
display when Linux takes over
|
||||
|
||||
* Patch by Erwin Rol, 27 Feb 2003:
|
||||
Add support for RTEMS (this time for real).
|
||||
|
||||
* Add support for "bmp info" and "bmp display" commands to load
|
||||
bitmap images; this can be used (for example in a "preboot"
|
||||
command) to display a splash screen very quickly after poweron.
|
||||
|
||||
* Add support for 133 MHz clock on INCA-IP board
|
||||
|
||||
* 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:
|
||||
Changed DHCP client to use IP address from server option field #54
|
||||
from the OFFER packet in the server option field #54 in the REQUEST
|
||||
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
|
||||
|
||||
* Add support for TQM862L modules

||||

Z* The keyboard controller is initialized and the result

Z* of a read copied to the environment variable "keybd".

Z* If KEYBD_SET_DEBUGMODE is defined, a check is made for

Z* The keys in "keybd" are checked against the magic
