The following changes allow U-Boot to fully relocate from flash to
RAM:
- Remove linker scripts' .fixup sections from the .text section
- Add -mrelocatable to PLATFORM_RELFLAGS for all boards
- Define CONFIG_RELOC_FIXUP_WORKS for all boards
Previously, U-Boot would partially relocate, but statically initialized
pointers needed to be manually relocated.

This patch merges the ECC handling (ECC parity byte writing) into one
file (ecc.c) for all PPC4xx SDRAM controllers except for PPC440EPx/GRx.
This exception is because only those PPC's use the completely different
Denali SDRAM controller core.
Previously we had two routines to generate/write the ECC parity bytes.
With this patch we now only have one core function left.
Tested on Kilauea (no ECC) and Katmai (with and without ECC).

The MPC8536E is capable of booting from the on-chip ROM - boot from
eSDHC and boot from eSPI. When power on, the porcessor excutes the
ROM code to initialize the eSPI/eSDHC controller, and loads the mian
U-Boot image from the memory device that interfaced to the controller,
such as the SDCard or SPI EEPROM, to the target memory, e.g. SDRAM or
L2SRAM, then boot from it.
The memory device should contain a specific data structure with control
word and config word at the fixed address. The config word direct the
process how to config the memory device, and the control word direct
the processor where to find the image on the memory device, or where
copy the main image to. The user can use any method to store the data
structure to the memory device, only if store it on the assigned address.
The on-chip ROM code will map the whole 4GB address space by setting
entry0 in the TLB1, so the main image need to switch to Address space 1
to disable this mapping and map the address space again.
This patch implements loading the mian U-Boot image into L2SRAM, so
the image can configure the system memory by using SPD EEPROM.

MPC8536E can support booting from NAND flash which uses the
image u-boot-nand.bin. This image contains two parts: a 4K
NAND loader and a main U-Boot image. The former is appended
to the latter to produce u-boot-nand.bin. The 4K NAND loader
includes the corresponding nand_spl directory, along with the
code twisted by CONFIG_NAND_SPL. The main U-Boot image just
like a general U-Boot image except the parts that included by
CONFIG_SYS_RAMBOOT.
When power on, eLBC will automatically load from bank 0 the
4K NAND loader into the FCM buffer RAM where CPU can execute
the boot code directly. In the first stage, the NAND loader
copies itself to RAM or L2SRAM to free up the FCM buffer RAM,
then loads the main image from NAND flash to RAM or L2SRAM
and boot from it.
This patch implements the NAND loader to load the main image
into L2SRAM, so the main image can configure the RAM by using
SPD EEPROM. In the first stage, the NAND loader copies itself
to the second to last 4K address space, and uses the last 4K
address space as the initial RAM for stack.
Obviously, the size of L2SRAM shouldn't be less than the size
of the image used. If so, the workaround is to generate another
image that includes the code to configure the RAM by SPD and
load it to L2SRAM first, then relocate the main image to RAM
to boot up.

By nature of being based off the MPC8548CDS board, this
board inherited an ENV_SIZE setting of 256k. But since
it has a smaller flash device (8MB soldered on), it has
a native sector size of 128k, and hence the ENV_SIZE was
causing 2 sectors to be used for the environment.
By removing the unused sector, we can push TEXT_BASE up
closer to the end of address space and reclaim that
sector for any other application. This also fixes the
mismatch between TEXT_BASE and MONITOR_LEN reported by
Kumar earlier.
Since this board also supports the ability to boot off
the 64MB SODIMM flash, this change is forward looking
with that in mind; i.e. the settings for MONITOR_LEN
and ENV_SIZE will work when the 512k sectors of the
SODIMM flash are used for alternate boot in the future.

The PCI/PCI-e support for the sbc8548 was based on an earlier
version of what the MPC8548CDS board was using, and in its
current state it won't even compile. This re-syncs it to match
the latest codebase and makes use of the new shared PCI functions
to reduce board duplication.
It borrows from the MPC8568MDS, in that it pulls the PCI-e I/O
back to 0xe280_0000 (where PCI2 would be on MPC8548CDS), and
similarly it coalesces the PCI and PCI-e mem into one single TLB.

The sbc8548 has a 64MB SODIMM flash module off of CS6 that
previously wasn't enumerated by u-boot. There were already
BR6/OR6 settings for it [used by cpu_init_f()] but there
was no TLB entry and it wasn't in the list of flash banks
reported to u-boot.
The location of the 64MB flash is "pulled back" 8MB from
a 64MB boundary, in order to allow address space for the
8MB boot flash that is at the end of 32 bit address space.
This means creating two 4MB TLB entries for the 8MB chunk,
and then expanding the original boot flash entry to 64MB
in order to cover the 8MB boot flash and the remainder
(56MB) of the user flash.

The Calao TNY-A9260 and TNY-9G20 are boards manufactured and sold by
Calao Systems <http://www.calao-systems.com>. Their components are very
similar to the AT91SAM9260EK board, so their configuration is based on
the configuration of this board. There are however some differences:
different clocks, no LCD, no ethernet. They also can use SPI EEPROM to
store the environment.

This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)
Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT
Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.
for-ex.
setenv sysrst_cmd "echo starting factory reset;
nand erase 0xa0000 0x20000;
echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event

P1020 is another member of QorIQ series of processors which falls in ULE
category. It is an e500 based dual core SOC.
Being a scaled down version of P2020 it has following differences:
- 533MHz - 800MHz core frequency.
- 256Kbyte L2 cache
- Ethernet controllers with classification capabilities.
Also the SOC is pin compatible with P2020

The old PCI ATMU setup code would just mimic the PCI regions into the
ATMU registers. For simple memory maps in which all memory, MMIO, etc
space fit into 4G this works ok. However there are issues with we have
>4G of memory as we know can't access all of memory and we need to
ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with
anything since we can't turn it off.
We first setup outbound windows based on what the board code setup
in the pci regions for MMIO and IO access. Next we place PCICSRBAR
below the MMIO window. After which we try to setup the inbound windows
to map as much of memory as possible.
On PCIe based controllers we are able to overmap the ATMU setup since
RX & TX links are separate but report the proper amount of inbound
address space to the region tracking to ensure there is no overlap.
On PCI based controllers we use as many inbound windows as available to
map as much of the memory as possible.
Additionally we changed all the CCSR register access to use proper IO
accessor functions. Also had to add CONFIG_SYS_CCSRBAR_PHYS to some
86xx platforms that didn't have it defined.

This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to
support 4-bit ECC on TI DaVinci devices with large page (up to 2K) NAND
chips. This ECC mode is similar to NAND_ECC_HW, with the exception of
read_page API that first reads the OOB area, reads the data in chunks,
feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.
