* Fix environment problems on SMDK2400 and TRAB boards
* Make environment layout backward compatible
when no redundancy is used
* Fix network problems on ARM caused by alignment restrictions
Merging ARMBoot patches per Sep 23 22:12 MEST:
- network patch by Robert Kaiser:
o need to handle byte order for Netmask, Gateway IP, etc.
- fixes in 3c589 driver:
o set correct MAC address
o add delay to make sure board is ready to transmit
o TX data must be padded to *double* words (4 bytes)
Patch by Stefan Röse, 20 Sep 2002:
- CPCI4052: new FPGA image included, jffs2 support added.
- DU405, OCRTC and ORSG init ram moved to OCM.
- Bug for ORSG VxWorks boot (cmd_elf.c) fixed.
* Patch by Scott McNutt, 27 Aug 2002:
1. PCI support added (README.ppc440 has some details).
2. SPD DRAM initialization added.
3. Support for Rev B silicon added:
-Fixed ethernet (errata: requires MAL bursting disabled)
-Fixed corrupted dcrs: fix strap regs & chip reset(errata)
-Fixed speed related calculations (Rev B. has addl div by 2)
4. Flash initialization: added delays to prevent timing
issues (band-aid) --needs more investigation, but this is
in the board-specific code.
5. Fixed do_reset (changed SPRN for 440).
6. Fixed get_tbclk for 440 (used same style as 405gp).
7. Initialized all interrupt vector regs (start.S)
8. Added doc/README.ppc440
* Patch by Keith Outwater, 23 Aug 2002:
Added support for generic 860T system (GEN860T). See README in
board/gen860t for details.
* Patch by Scott McNutt, 20 Aug 2002:
initialize the 440 interrupt vector registers (IVORs) and enable
the PIT. The PIT is set to interrupt every 10 msec.
* Patch by Kenneth Johansson, 19 Aug 2002:
add some documentation for jffs2 to make it possible to change the
partition with code instead of #defines, usage of a global in
jffs2_1pass.c.
* Add support for redundand environment, so the previous settins
don't get lost in case of a power failure right during a "saveenv"
command.
Major restructuring and cleanup of the environment handling.
* Patch by Stefan Roese, 18 Jul 2002:
Removed board init.S from esd AR405, CANBT, CPCIISER4, OCRTC
targets -> no (E)ABI violation anymore with r31 usage (setup
moved to config files).

Commented test routines [2 Sep 2002 19:27:01]
* Patch by Josef Wagner, 12 Sep 2002:
Fix I2C on IP860 Board
* Modified LWMON configuration: use FRAM instead of EEPROM,
use hardware (CPM) I2C for higher speed
* Removed udelay() which broke CPM I2C code on MPC8xx
(We cannot use udelay() if I2C is used to hold the environment,
since timers are not yet running when we need I2C then.)
* Patch by Ranjit Deshpande, 11 Sep 2002:
Fixed CONFIG_[READ|WRITE]_WORD and CONFIG_[READ|WRITE]_HALFWORD
macros in mpc824x.h to use "base" registers instead of any GPR
(avoiding the use of R0) for indexing in indexed load and store
instructions.
* Fix problems in the password authorization mechanism
* Fix problem on PCIPPC2 board: reading /dev/flasha and copying the
data over NFS immediately hangs the system

- The "mm" command now accepts the "-" key stroke to go back to the
previous address.
* Patch by Denis Peter, 29 Jul 2002:
- waits for ATA_STAT_DRQ instead for ATA_STAT_RDY in
ide_ident. This has two reasons:
1. ATAPI devices doesn't set the RDY bit
2. Only read the inquiry data if the drive is ready to transmit.
- added check powermode command, to check the powermode
of the connected drive. If the drive is in standby, the
IDE_SPIN_UP_TIME_OUT is used instead of the IDE_TIME_OUT.
- various fixes in the ATAPI part, to get more IDE CDROMs to work.
- fixes in cmd_ide.c and part_iso.c for CD boot
- added check powermode in cmd_ide.c to expand the IDE timeout
when the drive is in power-down.

#1: - allow generation of GNU stabs line number debugging symbols
for assembly sources ; this allows symbolic debugging of
assembly files.
- fix probelms due to CYGWIN patches
#2: - Fix BEDBUG lossage when using GPR 0 in assembly mode.
- Allow BEDBUG to have a choice in whitespace between operand
delimiters.
- All PPC40x targets had the wrong cacheline size defined in
their config files. It should be 32 bytes for 405's and 16
bytes for CPUs prior to the 405.
- Make sure boards don't use deprecated CONFIG_4xx anymore.
- Make sure 405 MAL Ethernet buffer descriptors are malloc'd
and aligned on cache boundaries instead of being located at
a hard coded address. This was causing lossage on boards
with less than 16MB of RAM.
- IBM Walnut boards use 33.3Mhz clocks. Prevents rounding.
- Added a couple of 4xx specific defines.
#3: - Fix compiler warnings
- Make sure inline assembly statements properly flag
registers that are being modified.
#4: - cleanup of common/cmd_i2c.c; eliminated board specific
conditionals; eliminated deprecated CONFIG_I2C405 config
option.
- Added _i2c_bus_reset function to ${CPU}/ppc4xx/i2c.c to
handle reset edge condition which was causing EEPROM data
corruption. See doc/I2C_Edge_Conditions for details.
#5: - Add generic SDRAM SPD, "Serial presence detect," routines.
These should work with any 405 based boards that are using
SPD.
- Make IBM Walnut target use these new routines.
- Added ablility to place initial stack into 405's OCM, "On
Chip Memory."
- Added resetvec address to initial stack to aid in debugging
and also cause a reset in the event of an underflow.
#6: - Add digital temperature and thermostat support
- Add support for Dallas DS1621 and On Semi's LM75 DTTs.
- Add command to support the DTTs.
