83xx processor family has many reset sources, such as
power on reset, software hard reset, software soft reset,
JTAG, bus monitor, software watchdog, check stop reset,
external hard reset, external software reset.
sometimes, to figure out the fault of system, we need to
know the cause of reset early before the prompt of
u-boot present.

During config transactions on the PCIe bus an attempt to scan for a
non-existent device can lead to a machine check exception with certain
peripheral devices. In order to avoid crashing in such scenarios the
instrumented versions of the config cycle read routines are introduced, so
the exceptions fixups framework can gracefully recover.

The relocation fixup didn't handle the malloc pointer initialization
correctly. This patch fixes this problem. Tested successfully on 4xx.
The relocation fixup patches for 4xx will follow soon.

Fixed some broken instances of "#ifdef CMD_CFG_IDE" too.
Those always evaluated TRUE, and thus were always compiled
even when IDE really wasn't defined/wanted.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.
All transformations are of the form:
Before:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
#if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

- Show on the Status LEDs, some States of the board.
- Get the MAC addresses from the EEProm
- use PREBOOT
- use the CF on the board.
- check the U-Boot image in the Flash with a SHA1
checksum.
- use dynamic TLB entries generation for the SDRAM

Search the exception table with linear algorithm instead of
bisecting algorithm.
Because the exception table might be unsorted.
Signed-off-by: Roy Zang <tie-fei.zang@freescale.com>
The original search_one_table() function code can only processes the search
for the exception occurring in FLASH/ROM, because the exception and fixup
table usually locate in FLASH. If the exception address is also in
FLASH, it will be OK.
If the exception occurs in RAM, after the u-boot relocation, a
relocation offset should be added.

1. Add 7447A and 7448 processor support.
2. Add the following flags.
CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically
(such as by switch on board), this flag should be set.
CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot
relocates to RAM, this flag should be set.
CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the
system hang in exception, this flag should be set.

- Add support for PPC440EPx & PPC440GRx
- Add support for PPC440EP(x)/GR(x) NAND controller
in cpu/ppc4xx directory
- Add NAND boot functionality for Sequoia board,
please see doc/README.nand-boot-ppc440 for details
- This Sequoia NAND image doesn't support environment
in NAND for now. This will be added in a short while.
Patch by Stefan Roese, 07 Sep 2006
Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
Added code for reading and writing Mac addresses to/from ID EEPROM(0x57).
With attached patch, we can use command "mac/mac read/mac save/"
to read and write EEPROM under u-boot prompt.
U-boot will calculate the checksum of EEPROM while bootup,
if it is right, then u-boot will check whether the mac address
of eTSEC0/1/2/3 is availalbe (non-zero).
If there is mac address availabe in EEPROM, u-boot will use it,
otherewise, u-boot will use the mac address defined in
MPC8641HPCN.h. This matches the requirement to set unique mac address
for each TSEC port.

- Support for TQM8541/8555 boards added.
- Complete rework of TQM8540/8560 support.
- Common TQM85xx code now supports all current TQM85xx platforms
(TQM8540/8541/8555/8560).
- DDR SDRAM size detection added.
- CAS latency default values can be overwritten by setting "serial#"
to e.g. "ABC0001 casl=25" -> CAS latency 2.5 will be used.
If problems are detected with this non default CAS latency,
the defualt values will be used instead.
- FLASH size detection added.
- Moved FCC ethernet driver initialization behind TSEC driver init
-> TSEC is first device.

The global data pointer, stored in r29 before relocation to RAM, was
not initialized to a correct value. This happened because the pointer
declaration was done locally in the scope of the board_init_f()
function. What follows is a cite from gcc.info, 5.37, "Variables in
Specified Registers":
...
The compiler's data flow analysis is capable of determining where
the specified registers contain live values, and where they are
available for other uses. Stores into local register variables
may be deleted when they appear to be dead according to dataflow
analysis. References to local register variables may be deleted
or moved or simplified.
...
Moving the global data declaration to global scope solved the
problem.

- 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.
* Cleanup confusing use of CONFIG_ETH*ADDR - ust his only to
pre-define a MAC address; use CONFIG_HAS_ETH* to enable support for
additional ethernet addresses.
* Cleanup drivers/i82365.c - avoid duplication of code
* Fix bogus "cannot span across banks" flash error message
* Add support for CompactFlash for the CPC45 Board.
