Changes for U-Boot 1.1.3:
======================================================================
* Patch by Jon Loeliger
Fix style issues primarily in 85xx and 83xx boards.
- C++ comments
- Trailing white space
- Indentation not by TAB
- Excessive amount of empty lines
- Trailing empty lines
* Patch by Ron Alder, 11 Jul 2005
Add Xianghua Xiao and Lunsheng Wang's support for the
GDA MPC8540 EVAL board.
* Patch by Eran Liberty
Add support for the Freescale MPC8349ADS board.
* Patch by Jon Loeliger, 25 Jul 2005
Move the TSEC driver out of cpu/mpc85xx as it will be shared
by the upcoming mpc83xx family as well.
* Patch by Jon Loeliger, 05 May 2005
Implemented support for MPC8548CDS board.
Added DDR II support based on SPD values for MPC85xx boards.
This roll-up patch also includes bugfies for the previously
published patches:
DDRII CPO, pre eTSEC, 8548 LBIU, Andy's TSEC, eTSEC 3&4 I/O
* Patch by Jon Loeliger, 10 Feb 2005
Add config option CONFIG_HAS_FEC calling out 8540 FEC features.
* Patch by Jon Loeliger, Kumar Gala, 08 Feb 2005
For MPC85xxCDS:
Adds Relaxed Timing TRLX bit to FLASH ORx regs to allow
for faster flash parts.
Add documentation for BR/OR for FLASH.
* Patch by Jon Loeliger 08 Feb 2005
Determine L2 Cache size dynamically on 85XX boards.
* Patch by Jon Loeliger, Kumar Gala 08 Feb 2005
- Convert the CPM2 based functionality to use new CONFIG_CPM2
option rather than a myriad of CONFIG_MPC8560-like variants.
Applies to MPC85xx and MPC8260 boards, includes stxgp3 and sbc8560.
Eliminates the CONFIG_MPC8560 option entirely. Distributes the
new CONFIG_CPM2 option to each 8260 board.
* Add support for MicroSys PM856 board

0xfe00_0000 0xffff_ffff FLASH (boot bank) 16M
3. Definitions
3.1 Explanation of NEW definitions in:
include/configs/MPC8349ADS.h
CONFIG_MPC83xx MPC83xx family
CONFIG_MPC8349 MPC8349 specific
CONFIG_MPC8349ADS MPC8349ADS board specific
CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet
4. Compilation
Assuming you're using BASH shell:
export CROSS_COMPILE=your-cross-compile-prefix
cd u-boot
make distclean
make MPC8349ADS_config
make
5. Downloading and Flashing Images
5.0 Download over serial line using Kermit:
loadb
[Drop to kermit:
^\c
send <u-boot-bin-image>
c
]
Or via tftp:
tftp 10000 u-boot.bin
5.1 Reflash U-boot Image using U-boot
tftp 10000 u-boot.bin
protect off fe000000 fe09ffff
erase fe000000 fe09ffff
cp.b 10000 fe000000 xxxx
or
cp.b 10000 fe000000 a0000
You might have to supply the correct byte count for 'xxxx' from
the TFTP. Maybe a0000 will work too, that corresponds to the
erased sectors.
