We do not have to define CONFIG_4xx in board config headers
because it is defined in arch/powerpc/cpu/ppc4xx/config.mk.
include/configs/JSE.h defines "CONFIG_4x", not "CONFIG_4xx".
I believe it is a typo because "CONFIG_4x" is not used at all
in other files.
So, I also deleted "CONFIG_4x" in include/configs/JSE.h.

The pci_indirect.c file is always compiled when
CONFIG_PCI is defined although the indirect PCI
bridge support is not needed by every board.
Introduce a new CONFIG_PCI_INDIRECT_BRIDGE
config option and only compile indirect PCI
bridge support if this options is enabled.
Also add the new option into the configuration
files of the boards which needs that.
Compile tested for powerpc, x86, arm and nds32.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be
some end address; to make the meaning more clear we rename it into
CONFIG_SYS_INIT_RAM_SIZE
No other code changes are performed in this patch, only minor editing
of white space (due to the changed length) and the comments was done,
where noticed.
Note that the code for the PATI and cmi_mpc5xx board configurations
looks seriously broken. Last known maintainers on Cc:

Clean up Makefile, and drop a lot of the config.mk files on the way.
We now also automatically pick all boards that are listed in
boards.cfg (and with all configurations), so we can drop the redundant

This patch removes the PPC4xx UART driver. Instead the common NS16550
driver is used, since all PPC4xx SoC's use this peripheral device.
The file 4xx_uart.c now only implements the UART clock calculation
function which also sets the SoC internal UART divisors.
All PPC4xx board config headers are changed to use this common NS16550
driver now.
Tested on these boards:
acadia, canyonlands, katmai, kilauea, sequoia, zeus

The 440SPe Rev. A is quite old and newer 440SPe boards don't need support
for this CPU revision. Since removing support for this older version
simplifies the creation for newer U-Boot ports, this patch now enables
440SPe > Rev. A support by creating the CONFIG_440SPE_REVA define. By
defining this in the board config header, Rev. A will still be supported.
Otherwise (default for newer board ports), Rev. A will not be supported.

CONFIG_SDRAM_PPC4xx_IBM_DDR2 is not set when include/asm-ppc/config.h is
included. So for katmai, CONFIG_MAX_MEM_MAPPED will get set to 256MB.
It makes perfect sense to set CONFIG_MAX_MEM_MAPPED to 2GB for all PPC4xx
boards right now.

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.

Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.
Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

This patch series unifies the AMCC eval board ports by introducing
a common include header for all AMCC eval boards:
include/configs/amcc-common.h
This header now includes all common configuration options/defines which
are removed from the board specific headers.
The reason for this is ease of maintenance and unified look and feel
of all AMCC boards.

On Katmai the complete auto-calibration somehow doesn't seem to
produce the best results, meaning optimal values for RQFD/RFFD.
This was discovered by GDA using a high bandwidth scope,
analyzing the DDR2 signals. GDA provided a fixed value for RQFD,
so now on Katmai "only" RFFD is auto-calibrated.
This patch also adds RDCC calibration as mentioned on page 7 of
the AMCC PowerPC440SP/SPe DDR2 application note:

On Yucca & Katmai, the inbound memory map pointed to 0x4.0000.0000, which
is the internal SRAM. Since I now ported and tested this endpoint mode
on Kilauea successfully to map to 0 (SDRAM), I also changed this for
Katmai.
Yucca will stay at internal SRAM for now. Not sure if somebody relies on
this setup.

This patch adds support for dynamic configuration of PCIe ports for the
AMCC PPC4xx boards equipped with PCIe interfaces. These are the PPC440SPe
boards Yucca & Katmai and the 405EX board Kilauea.
This dynamic configuration is done via the "pcie_mode" environement
variable. This variable can be set to "EP" or "RP" for endpoint or
rootpoint mode. Multiple values can be joined via the ":" delimiter.
Here an example:
pcie_mode=RP:EP:EP
This way, PCIe port 0 will be configured as rootpoint, PCIe port 1 and 2
as endpoint.
Per default Yucca will be configured as:
pcie_mode=RP:EP:EP
Per default Katmai will be configured as:
pcie_mode=RP:RP:REP
Per default Kilauea will be configured as:
pcie_mode=RP:RP

128MB seems to be the smallest possible value for the memory size
for on PCIe port. With this change now the BAR's of the PCIe cards
are accessible under U-Boot.
One big note: This only works for PCIe port 0 & 1. For port 2 this
currently doesn't work, since the base address is now 0xc0000000
(0xb0000000 + 2 * 0x08000000), and this is already occupied by
CFG_PCIE0_CFGBASE. But solving this issue for port 2 would mean
to change the base addresses completely and this change would have
too much impact right now.
This patch adds debug output to the 4xx pcie driver too.

- 'pciconfighost' is set by default in order to be able to scan bridges
behind the primary host/PCIe
- 'pciscandelay' env variable is recognized to allow for user-controlled
delay before the PCIe bus enumeration; some peripheral devices require a
significant delay before they can be scanned (e.g. LSI8408E); without the
delay they are not detected

- correct configuration space mapping
- correct bus numbering
- better access to config space
Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the
first device on the first bus. We now allow to configure up to 16 buses;
also, scanning for devices behind the PCIe-PCIe bridge is supported, so
peripheral devices farther in hierarchy can be identified.
