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:

The patch adds the possibility to update the QONG
FPGA (a Lattice XP2-5E) with u-boot using some GPIOs
to drive the JTAG interface.

There were some #undef's of CONFIG_SYS_ARM_WITHOUT_RELOC added to a few board
configs as part of the arm relocation series; but these are not needed now as we
do not #undef what is not #defined in the first place.

The handling of the SPI_CPOL bit inside the SPI
driver was wrong. As reported by the manual,
the meaning of the SSPOL inside the
configuration register is the same as reported
by SPI specification (0 if low in idle, 1 is high
on idle). The driver inverts this logic.
Because this patch sets the logic as specified, it is required
to clear the CPOL bit in the configuration file to adapt
to the correct logic.

The patch adds support for setting gpios to the
MX51 processor and change name to the corresponding
functions for MX31. In this way, it is possible to get rid
of nasty #ifdef switches related to the processor type.

Add data cache support for arm1136 systems.
Enable "cache" command on Qong board and test performance.
Test 1: Loading 127 MB of data from NAND flash into RAM:
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
QONG (ARM11) 177s 95s 43s = x 4.1
Test 2: uncompressing a gzipped image from RAM to RAM
(size compressed: 6.5 MiB, uncompressed: 35 MiB):
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
QONG (ARM11) 1.54s 0.95s 0.18s = x 8.6

The NAND device is connected to the FPGA of the QONG board
and not to the NFC controller. For this reason, the FPGA must
be set and initialized before accessing to the NAND itself.

UART hardware on i.MX27 is the same as on the i.MX31 so we just
need to provide the driver with correct address of the registers.

By changing the cmd_mtdparts to only use the MTD infrastructure and
not the direct interface to the CFI NOR FLASH driver we now need
to add the MTD infrastructure to all boards using those mtdparts
commands. This patch adds those components:
CONFIG_MTD_DEVICE (for all FLASH types)
plus
CONFIG_FLASH_CFI_MTD (for NOR FLASH)
To all board maintainers: Please test this on your platforms and
report any problems/issues found. Thanks.

Currently the mtdparts commands are included in the jffs2 command support.
This doesn't make sense anymore since other commands (e.g. UBI) use this
infrastructure as well now. This patch separates the mtdparts commands from
the jffs2 commands making it possible to only select mtdparts when no JFFS2
support is needed.

1. Changes to the default environment:
- "bootcmd" defined as "run flash_self"
- "saveenv" command removed from "update"
- "uboot" changed to "u-boot" (also in "load")
- "addmtd" variable defined (and added to all boot commands)
2. CONFIG_CMD_JFFS2 defined to enable "mtdparts" command
3. MTDIDS_DEFAULT and MTDPARTS_DEFAULT defined
4. CONFIG_SYS_CBSIZE changed from 256 to 512. That solves the problem
with truncated "bootargs" environment variable.
