This patch adds NAND booting support for the AMCC Bamboo eval board.
Since the NAND-SPL boot image is limited to 4kbytes, this version
only supports the onboard 64MBytes of DDR. The DIMM modules can't be
supported, since the setup code for I2C DIMM autodetection and
configuration is too big for this NAND bootloader.

The U-Boot NAND booting support is now extended to support ECC
upon loading of the NAND U-Boot image.
Tested on AMCC Sequoia (440EPx) and Bamboo (440EP).

This patch updates the "normal" Bamboo NOR booting port, so
that it is compatible with the coming soon NAND booting
Bamboo port.
It also enables the 2nd NAND flash on the Bamboo.

This patch adds hardware ECC support to the NDFC driver. It also
changes the register access from using the "simple" in32/out32
functions to the in_be32/out_be32 functions, which make sure
that the access is correctly synced. This is the only recommended
access to SoC registers in the current Linux kernel.

This patch updates the nand_ecc code to the latest Linux version.
The main reason for this is the more compact code. This makes
it possible to include the ECC code into the NAND bootloader
image (NAND_SPL) for PPC4xx.

Previous versions used full wait states for the chip select #1 which
is connected to the Xilinix SystemACE controller on the AMCC Katmai
evaluation board. This leads to really slow access and therefore low
performance. This patch now sets up the chip select a lot faster
resulting in much better read/write performance of the Linux driver.

Now 405EZ ports also show upon bootup from which boot device
they are configured to boot:
U-Boot 1.2.0-gd3832e8f-dirty (Apr 18 2007 - 07:47:05)
CPU: AMCC PowerPC 405EZ Rev. A at 199.999 MHz (PLB=133, OPB=66, EBC=66 MHz)
Bootstrap Option E - Boot ROM Location EBC (32 bits)
16 kB I-Cache 16 kB D-Cache
Board: Acadia - AMCC PPC405EZ Evaluation Board

Fix bug introduced by "Fix get_partition_info() parameter error in all
other calls" from 2005-03-04 in cmd_ide.c and cmd_scsi.c, which prevented
to use diskboot or scsiboot form another device than 0.

This patch fixes changes the i2c_init(...) function to use the function
get_OPB_freq() rather than calculating the OPB speed by
sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is
specific per processor. The prior method was not and so was calculating
the wrong speed for some PPC4xx processors.

With this new base address of the Xilinx SystemACE controller
the Linux driver will be easier to adapt, since it can now be
mapped via the "normal" ioremap() call.

Modifications to the existing code to support the new fdt command.
|
|
The fdt command uses David Gibson's libfdt library to manipulate as well
as print the flattened device tree. This patch is the new command,
the second part is the modifications to the existing code.
|
|
Enhanced the formerly private function _fdt_next_tag() to allow stepping
through the tree, used to produce a human-readable dump, and made
it part of the published interface.
Also added some comments.
|
|
Changes to David Gibson's original source to fit into u-boot's
environment. No functionality changes.
|
|
This adds the applicable libfdt source files (unmodified) and a README
to explain where the source came from.
