Hello,
Attached is a patch implementing multiple I2C buses on the MPC834x CPU
family and the MPC8349EMDS board in particular.
This patch requires Patch 1 (Add support for multiple I2C buses).
Testing was performed on a 533MHz board.
/*** Note: This patch replaces ticket DNX#2006083042000027 ***/

CHANGELOG:
Implemented driver-level code to support two I2C buses on the
MPC834x CPU family and the MPC8349EMDS board. Available I2C bus speeds
are 50kHz, 100kHz and 400kHz on each bus.

Ben
Hello,
Attached is a patch providing support for multiple I2C buses at the
command level. The second part of the patch includes an implementation
for the MPC834x CPU and MPC8349EMDS board.

Overview:
1. Include new 'i2c' command (based on USB implementation) using
CONFIG_I2C_CMD_TREE.
2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that
the commands to change bus number and speed are only available under the
new 'i2c' command mentioned in the first bullet.
3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus
systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form
of an array of bus-device pairs. Otherwise, it is an array of uchar.
CHANGELOG:
Added new 'i2c' master command for all I2C interaction. This is
conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for
setting I2C bus speed as well as changing the active bus if the board
has more than one (conditionally compiled with
CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses.
Updated README.
regards,
Ben
CHANGELOG:
* Errata DDR6, which affects all current MPC 834x processors, lists changes
required to maintain compatibility with various types of DDR memory. This
patch implements those changes.

CHANGELOG:
* On 83xx systems, use the CFG_FLASH_SIZE macro to program the LBC local access
window registers, instead of using a hard-coded value of 8MB.

This patch addresses a problem when CONFIG_MTD_NAND_VERIFY_WRITE is
defined
and the write crosses a block boundary. The pointer to the verification
buffer (bufstart) is not being updated to reflect the starting of the
new
block so the verification of the second block fails.
CHANGELOG:
* Fix NAND FLASH page verification across block boundaries
Added a phy initialization to adjust the RGMII RX and TX timing
Always set the R100 bit in 100 BaseT mode regardless of the TSEC mode

* remove warnings when compiling ethaddr.c
* adjust linker script (fixes a crash resulting from incorrect
definition of __u_boot_cmd_start)
- Some MarelV38B code cleanup.
MPC5XXX_WU_GPIO_DATA macro to MPC5XXX_WU_GPIO_DATA_O (per MPC5200 User's
Manual). Replace the uses of MPC5XXX_WU_GPIO_DATA with
MPC5XXX_WU_GPIO_DATA_O for affected boards.
- Add defintions for some MPC5XXX GPIO pins.
Use MACH_TYPE_NETSTAR and MACH_TYPE_VOICEBLUE defines instead of
numbers in code.

Make sure the string passed as variable name does not contain a '='
character. This not only prevents the common error or typing
"setenv foo=bar" instead of "setenv foo bar", but (more importantly)
also closes a backdoor which allowed to delete write-protected
environment variables, for example by using "setenv ethaddr=".
When passing the -g option to gcc, gcc automatically selects a
suitable --g<format> option to pass on to the assembler.
Thus, there's no point in forcing a specific debug option on the
assembler using the -Wa mechanism.

Add atstk1002_config target to Makefile and move the AVR32 section
down below Blackfin so that it doesn't end up in the middle of
MIPS.
Drop the autogenerated linker script thing for now. Will have to
revisit how to handle chips with different flash and RAM layout
later.

If a Multi-Image file contains a third image we try to use it as a
device tree. The device tree image is assumed to be uncompressed in the
image file. We automatically allocate space for the device tree in memory
and provide an 8k pad to allow more than a reasonable amount of growth.
Additionally, a device tree that was contained in flash will now automatically
get copied to system memory as part of boot. Previously an error was
reported if one tried to boot a device tree that was in flash.

This patch adds support for the ATSTK1000 with the ATSTK1002 CPU
daughterboard.
ATSTK1000 is a full-featured development board for AT32AP CPUs. It
has two ethernet ports, a high quality QVGA LCD panel, a loudspeaker,
and connectors for USART, PS/2, VGA, USB, MMC/SD cards and
CompactFlash cards. For more information, please see this page:
http://www.atmel.com/dyn/products/tools.asp?family_id=682
The ATSTK1002 is a daughterboard for the ATSTK1000 supporting the
AT32AP7000 chip.

Patch by Haavard Skinnemoen, 06 Sep 2006
This is a first attempt at creating a common serial driver for Atmel
chips. For now, it supports the AT32AP7000 AVR32 chip, but it should
be possible to support AT91RM9200 and other ARM-based chips with some
minor modifications.
There's nothing fundamentally AVR32-specific in this driver, but it
does use some features which are currently only defined for the
AT32AP CPU port:
* pm_get_clock_freq: Obtain the clock frequency of a given domain
* gd->console_uart: A "struct device" containing information about
register mappings, gpio resources and clocks associated with the
UART device.
For more information about these features, please see the "AT32AP
CPU" patch.
Patch by Haavard Skinnemoen, 06 Sep 2006
This patch adds support for the AT32AP CPU family and the AT32AP7000
chip, which is the first chip implementing the AVR32 architecture.
The AT32AP CPU core is a high-performance implementation featuring a
7-stage pipeline, separate instruction- and data caches, and a MMU.
For more information, please see the "AVR32 AP Technical Reference":
http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf
In addition to this, the AT32AP7000 chip comes with a large set of
integrated peripherals, many of which are shared with the AT91 series
of ARM-based microcontrollers from Atmel. Full data sheet is
available here:
