mpc83xx: Fix the incorrect dcbz operation
The 834x rev1.x silicon has one CPU5 errata.
The issue is when the data cache locked with
HID0[DLOCK], the dcbz instruction looks like no-op inst.
The right behavior of the data cache is when the data cache
Locked with HID0[DLOCK], the dcbz instruction allocates
new tags in cache.
The 834x rev3.0 and later and 8360 have not this bug inside.
So, when 834x rev3.0/8360 are working with ECC, the dcbz
instruction will corrupt the stack in cache, the processor will
checkstop reset.
However, the 834x rev1.x can work with ECC with these code,
because the sillicon has this cache bug. The dcbz will not
corrupt the stack in cache.
Really, it is the fault code running on fault sillicon.
This patch fix the incorrect dcbz operation. Instead of
CPU FP writing to initialise the ECC.
CHANGELOG:
* Fix the incorrect dcbz operation instead of CPU FP
writing to initialise the ECC memory. Otherwise, it
will corrupt the stack in cache, The processor will checkstop
reset.

Add support for multiple I2C buses
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.
/*** Note: This patch replaces ticket DNX#2006083042000018 ***/
Signed-off-by: Ben Warren <bwarren@qstreams.com>
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

NAND Flash verify across block boundaries
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

logic always assert IRQ7 to CPU even if there is no request from the

the Linux kernel will think that the compact flash is requesting irq
and get stuck when it tries to clear the IRQ. Thus we need to set
the L2_IRQ0 and L2_IRQ1 to active low.
The following code sets the L1_IRQ and L2_IRQ polarity to active low.
Without this code, compact flash will not work in Linux because
unlike U-Boot, Linux uses the IRQ, so this code is necessary if we

* Program a UPM with the code supplied in the table.
*
* The 'dummy' variable is used to increment the MAD. 'dummy' is
* supposed to be a pointer to the memory of the device being
* programmed by the UPM. The data in the MDR is written into
* memory and the MAD is incremented every time there's a read
* from 'dummy'. Unfortunately, the current prototype for this
* function doesn't allow for passing the address of this
* device, and changing the prototype will break a number lots
* of other code, so we need to use a round-about way of finding
* the value for 'dummy'.
*
* The value can be extracted from the base address bits of the
* Base Register (BR) associated with the specific UPM. To find
* that BR, we need to scan all 8 BRs until we find the one that
* has its MSEL bits matching the UPM we want. Once we know the
* right BR, we can extract the base address bits from it.
*
* The MxMR and the BR and OR of the chosen bank should all be
* configured before calling this function.
*
* Parameters:
* upm: 0=UPMA, 1=UPMB, 2=UPMC
* table: Pointer to an array of values to program
* size: Number of elements in the array. Must be 64 or less.
