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 :-(.

The 'N' type Spansion flashes (S29GLxxxN series) have bigger sectors,
than the formerly used 'M' types (S29GLxxxM series), so the flash layout
needs to be changed -> new start address of the environment. The macro
definition CONFIG_TQM_FLASH_N_TYPE is undefined by default and must be
defined for boards with 'N' type flashes.

Do not configure port pins PD30/PD31 as SCC1 TxD/RxD except for the TQM8560
board. On the other TQM85xx boards (TQM8541 and TQM8555) SCC1 is not used
as serial interface anyway. Worse, on some board variants configuring the
pins for SCC1 leads to short circuits (for example on the TQM8541-BG).

This is a re-write of the NAND FSL UPM driver using the more universal
hwcontrol callback (instead of the cmdfunc callback). Here is a brief
list of furher modifications:
- For the time being, the UPM setup writing the UPM array has been
removed from the driver and must now be done by the board specific
code.
- The bus width definition in "struct fsl_upm_nand" is now in bits to
comply with the corresponding Linux driver and 8, 16 and 32 bit
accesses are supported.
- chip->dev_read is only set if fun->dev_ready != NULL, which is
required for boards not connecting the R/B pin.
- A few issue have been fixed with MxMR bit manipulation like in the
corresponding Linux driver.
Note: I think the "io_addr" field of "struct fsl_upm" could be removed
as well, because the address is already determined by
"nand->IO_ADDR_[RW]", but I'm not 100% sure.
This patch has been tested on a TQM8548 modules with the NAND chip
Micron MT29F8G08FABWP.

The current cpu identification code is used just to return the name
of the processor at boot. There are some other locations that the name
is useful (device tree setup). Expose the functionality to other bits
of code.
Also, drop the 'E' suffix and add it on by looking at the SVR version
when we print this out. This is mainly to allow the most flexible use
of the name. The device tree code tends to not care about the 'E' suffix.

This patch makes a couple of small cleanups to parameter checking of
libfdt functions.
- In several functions which take a node offset, we use an
idiom involving fdt_next_tag() first to check that we have indeed been
given a node offset. This patch adds a helper function
_fdt_check_node_offset() to encapsulate this usage of fdt_next_tag().
- In fdt_rw.c in several places we have the expanded version
of the RW_CHECK_HEADER() macro for no particular reason. This patch
replaces those instances with an invocation of the macro; that's what
it's for.
- In fdt_sw.c we rename the check_header_sw() function to
sw_check_header() to match the analgous function in fdt_rw.c, and we
provide an SW_CHECK_HEADER() wrapper macro as RW_CHECK_HEADER()
functions in fdt_rw.c
