We don't need to wait these extra 3 seconds because we now load UBIfied
which takes more time than these 3 seconds.
We also add the autoboot_select in config because it is a hidden feature
asked by diferent persons.

There is no need to do that, things work with full memory.

We need to reset the CPU outside of the whole loop. This moves stuff
around a lot to do that. Otherwise the variables are set after the CPU
already started, and it may be too late (it is too late in our
specific case).

This allos to write and read variable while loading rt_cpu.elf.
You can read a variable at run time, by not loading the elf file.
To do this use -n to "not" load the file:

   load-lm32 -n rt_cpu.elf pstate=

We still need the file to read the symbol table.  So, <var>= reads
the variable, and <write>=<value> changes it. You can pass several
such actions on the same command line. Please note that you can't
change variables in the BSS section, which is zeroed at run time.

All symbols are trated as 32-bit integer values, so this is not really
generic enough for everything:

  wrs-192.168.16.9# load-lm32 -n rt_cpu.elf memset=
  memset = 134253659 (0x08008c5b)

This is used by the next commit, where I read the symbol table of an ELF
file the lazy way.

I built the two binaries by rebuilding buildroot with

    BR2_PACKAGE_BINUTILS=y
    BR2_PACKAGE_BINUTILS_TARGET=y

but I won't add the whole binutils binary-set to the WR switch, so the
configuration items are still unset in the default configuration for
WR switch.

This removes the hack of forking a child, because I'll need to do more
than just passing a file name. The other tool using the same hack
(load-virtex) is unchanged as I don't need to work on it.

You can "diff -w" or "show -w" and see there is no difference. I
didn't shorten long lines nor anything "major", I just removed
trailing spaces, that are highlighted in my editor, and fixed
inconsistencies in indentation within functions.

We don't need the sdram printouts any more. But it's good to
have this in history anyways (it was an error having it in master,
but all hackers promote bugs as features).

With mem=64M we have some sdram corruption, with "bad page state".
This is unexplained, and the sam-ba code is so difficult to fix, that
we'd better just install with 32M of sdram.  At runtime we use a fixed
at91boot, so 64M work properly.

This actually has no effect, but since the item is there, we'd better
