The TQM8548_BE is a variant of the TQM8548 module with NAND and CAN
interface. With NAND support, the image is significantly larger and
TEXT_BASE is adjusted accordingly. U-Boot can be built for this
module with "$ make TQM8548_BE_config".

The TQM8548_AG module does not have the standard PCI/PCI-X interface
connected but just the PCI Express interface . So far it was not
possible to disable it without disabling the complete PCI interface
(CONFIG_PCI) including PCI Express.

As the reset vector is located at 0xfffffffc, all flash sectors from the
beginning of the U-Boot binary to 0xffffffff must be protected. On the
TQM8548-AG having small sectors at the end of the flash it happened that
the last two sector were not protected and an "erase all" left an
un-bootable system behind:
Bank # 2: CFI conformant FLASH (32 x 16) Size: 32 MB in 270 Sectors
AMD Standard command set, Manufacturer ID: 0xEC, Device ID: 0x257E
Erase timeout: 8192 ms, write timeout: 1 ms

The same bug seems to be in drivers/mtd/cfi_flash.c:flash_init() and many
board BSPs as well.

On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.
In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems. It
should be safe as the fifth bit was defined as reserved and set to 0.
Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

The information displayed when CONFIG_LCD_INFO is set is inherently
board-specific, so it should be done by the board code. The current code
dealing with this only handles two cases, and is already a horrible mess
of #ifdeffery.
Yes, this duplicates some code, but it also allows boards to print more
board-specific information; this used to be very difficult.

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.

A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.
This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.
MAKEALL ppc/arm has some issues:
* DOC/OneNand/nand_spl is not building (I have not tried porting
these parts, and since I do not have any HW and I am not familiar
with this code/HW I think its best left to someone else.)
Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
cpu/ppc4xx/ndfc.c
cpu/arm926ejs/davinci/nand.c
board/delta/nand.c
board/zylonite/nand.c

This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.
This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.
Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

Some TQM85xx boards could be equipped with up to 1 GiB (NOR) Flash
memory. The current memory map only supports up to 128 MiB Flash.
This patch adds the configuration option CONFIG_TQM_BIGFLASH. If
set, up to 1 GiB flash is supported. To achieve this, the memory
map has to be adjusted in great parts (for example the CCSRBAR is
moved from 0xE0000000 to 0xA0000000).
If you want to boot Linux with CONFIG_TQM_BIGFLASH set, the new
memory map also has to be considered in the kernel (changed
CCSRBAR address, changed PCI IO base address, ...). Please use
an appropriate Flat Device Tree blob (tqm8548.dtb).

This patch adds support for NAND FLASH on the TQM8548. It is disabled by
default and can be enabled for the TQM8548 modules. It is now based on
the re-written FSL NAND UPM driver. A patch has been posted earlier today
with the subject:
"NAND FSL UPM: driver re-write using the hwcontrol callback"
Note that the R/B pin is not supported by that module requiring to use
the specified maximum delay time.
Note: With NAND support enabled the size of the U-Boot image exceeds
256 KB and TEXT_BASE must therefore be set to 0xfff80000 in config.mk,
doubling the image size :-(.
