This patch enables support for EXT2, and increases the
CONFIG_SYS_BOOTMAPSZ size for the default configuration
of the katmai boards to use them as the RAID-reference
AMCC setups.
EXT2 enabling allows one to boot kernels from the EXT2
formatted Compact Flash cards.
CONFIG_SYS_BOOTMAPSZ increasing allows one to boot the
Linux kernels, which use PAGE_SIZE of 256KB. Otherwise,
the memory area with DTB file (which is placed at the
end of the bootmap area) will turn out to be overlapped
with the BSS segment of the 256KB kernel, and zeroed
in early_init() of Linux.
Actually, increasing of the bootmap size could be done
via setting of the bootm_size U-Boot variable, but it looks
like the current U-Boot implementation have some bootm_size-
related functionality lost. In many places through the U-Boot
code the CONFIG_SYS_BOOTMAPSZ definition is used directly
(instead of trying to read the corresponding value from the
environment). The same is truth for the boot_jump_linux()
function in lib_ppc/bootm.c, where U-Boot transfers control
to Linux passing the CONFIG_SYS_BOOTMAPSZ (not bootm_size)
value to the booting kernel.

Since we've changed the memory map of the board, be nice and
add some checking to try to catch out-of-date .dts files. We do
this by checking the CCSRBAR location in the .dts and comparing
it to the CCSRBAR location in u-boot. If they don't match, a
warning msg is printed. This isn't foolproof, but it's simple and
will catch most of the cases where an out-of-date .dts is present,
including all of the cases where a new u-boot is used with an old

This patch creates a memory map with all the devices
in 36-bit physical space, in addition to the 32-bit map.
The CCSR relocation is moved (again, sorry) to
allow for the physical address to be 36 bits - this
requires translation to be enabled. With 36-bit physical
addressing enabled, we are no longer running with VA=PA
translations. This means we have to distinguish between
the two in the config file. The existing region name is
used to indicate the virtual address, and a _PHYS variety
is created to represent the physical address.
Large physical addressing is not enabled by default.
Set CONFIG_PHYS_64BIT in the config file to turn this on.

The memory map on the 8641hpcn is modified to look more like
the 85xx boards; this is a step towards a more standardized

the flash.
The regions for some of the mappings were far larger than they
needed to be. I have reduced the mappings to match the
actual sizes supported by the hardware.
In addition I have removed the comments at the head
of the BAT blocks in the config file, rather than updating
them. These get horribly out of date, and it's a simple
matter to look at the defines to see what they are set to
since everything is right here in the same file.

This patch also enables FSL ELBC driver so that we could access

The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB,
standalone or acting as a PCI agent. User's Guide says:
- When the CPLD recognizes its location on the PIB it automatically
configures RCW to the PCI Host.
- If the CPLD fails to recognize its location then it is automatically
configured as an Agent and the PCI is configured to an external arbiter.
This sounds good. Though in the standalone setup the CPLD sets PCI_HOST
flag (it's ok, we can't act as PCI agents since we receive CLKIN, not
PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without
any arbiter bad things will happen (here the board hangs during any config
space reads).
In this situation we must disable the PCI. And in case of anybody really
want to use an external arbiter, we provide "pci_external_aribter"
environment variable.

This involves configuring the SerDes and fixing up the flags and
PHY addresses for the TSECs.
For Linux we also fix up the device tree.

Currently 64M of LBC SDRAM are mapped at 0xF0000000 which makes
it difficult to use (b/c then the memory is discontinuous and
there is quite big memory hole between the DDR/SDRAM regions).
This patch reworks LBC SDRAM setup so that now we dynamically
place the LBC SDRAM near the DDR (or at 0x0 if there isn't any
DDR memory).
With this patch we're able to:
- Boot without external DDR memory;
- Use most "DDR + SDRAM" setups without need to support for
sparse/discontinuous memory model in the software.

I reorganized my config files, putting the common stuff into netstal-common.h
(got the idea by looking a amcc-common.h from Stefan).
Added stuff to boot the new powerpc linux via NFS (only tested with HCU4).

The Arches Evaluation board is based on the AMCC 460GT SoC chip.
This board is a dual processor board with each processor providing
independent resources for Rapid IO, Gigabit Ethernet, and serial
communications. Each 460GT has it's own 512MB DDR2 memory, 32MB NOR
FLASH, UART, EEPROM and temperature sensor, along with a shared debug
port. The two 460GT's will communicate with each other via shared
memory, Gigabit Ethernet and x1 PCI-Express.

Several customers have reported problems with the environment in
EEPROM, including corrupted content after board reset. Probably the
code to prevent I2C Enge Conditions is not working sufficiently.
We move the environment to flash now, which allows to have a backup
copy plus gives much faster boot times.
Also, change the default console initialization to 115200 bps as used
on most other boards.

The pixis sgmii command depend on the FPGA support on the board, some 85xx
boards support SGMII riser card but did not support this command, define
CONFIG_PIXIS_SGMII_CMD for those boards which support the sgmii command.
Not like 8544, 8572 has 4 eTsec so that the other two's pixis bits
are not supported by 8544. Therefor, define PIXIS_VSPEED2_MASK and
PIXIS_VCFGEN1_MASK in header file for both boards.

* Add board specific parameter table to choose correct cpo, clk_adjust,
write_data_delay, 2T based on board ddr frequency and n_ranks.
* Set odt_rd_cfg and odt_wr_cfg based on the dimm# and CS#.
* Set memory controller interleaving mode to bank interleaving, and disable
bank(chip select) interleaving mode by default, because the default on-board
DDR DIMMs are 2x512MB single-rank.
* Change CONFIG_ICS307_REFCLK_HZ from 33333333 to 33333000.
