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:

Now that warm booting is not supported, there isn't a need for the
BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them.
Note that this change makes the board info bd_bootflags field useless.
It will always be set to 0, but we leave it around so that we don't
break the board info structure that some OSes are expecting to be passed
from U-Boot.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

Newer Linux kernels can overrun the initial memory window used for
booting with their BSS area. When this happens, they overwrite the FDT
and silently fail to boot.
On e300 CPUs, the Linux kernel uses an initial BAT covering the first
256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase
the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value
allowed by Linux. This will allow very large kernels to boot.

impedance bits should be clear, i.e., SICRH[TSIOB1] = 0 and SICRH[TSIOB2] = 0.
SICRH[TSIOB1] was erroneously being set high.

The mpc8313erdb board currently sets DBAT6 to cover all of the final 256MiB of
address space; however, not all of this space is covered by a device. In
particular, flash sits at 0xfe000000-0xfe7fffff, and nothing is mapped
at the far end of the address space.
In zlib, there is a loop that references p[-1] if p is non-NULL. Under
some circumstances, this leads to the CPU speculatively loading from
0xfffffff8 if p is NULL. This leads to a machine check.
