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.

This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.

Configure CONFIG_SYS_MAX_RAM_SIZE address range in
DDR Local Access Window and determine the RAM size.
Fix DDR LAW afterwards using detected RAM size.

There is more and more usage of printing 64bit values,
so enable this feature generally, and delete the
CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL
defines.

Minor cleanup:
Re-ordered default_mddrc_config[] to have matching indices.
This allows to use the same index "N" for source and target fields;
before, we had code like this
out_be32(&im->mddrc.ddr_time_config2, mddrc_config[3]);
which always looked like a copy & paste error because 2 != 3.
Also, use NULL when meaning a null pointer.

Remove dead code that was obviously a left-over from copy & paste.

When enabling NAND support for a board, one must also define
CONFIG_SYS_64BIT_VSPRINTF because this is needed in nand_util.c
for correct output.
