We want to use the memory banks later in the MMU which is
independent of Linux, so move this to a location which is
always compiled.
Also, make the memory bank list global and add an iterator
for it.

The new MMU setup will need SDRAM base addresses and sizes.
For this reason convert the MMU enabled ARM boards:
- move mem setup to mem_initcall. This is early but
still makes sure that we already have the console available
- move MMU setup in this initcall temporary as after the mmu_init will generic

To: barebox
From: Sascha Hauer <s.hauer@pengutronix.de>
In barebox we used 1MiB sections to map our SDRAM cachable. This
has the drawback that we have to map our sdram twice: cached for
normal sdram and uncached for DMA operations. As address space gets
sparse on newer systems we are sometines unable to find a suitably
big enough area for the dma coherent space.
This patch changes the MMU code to use second level page tables.
With it we can implement dma_alloc_coherent as normal malloc, we
just have to remap the allocated area uncached afterwards and map
it cached again after free().
This makes arm_create_section(), setup_dma_coherent() and mmu_enable()
noops.

merged up to 7/9. The MMU rework needs some changes to v1 which I
haven't posted yet. It does not work correctly on armv7 as these
processors need slightly different second level page table entries.
Also, I added the appropriate KEEP directives to
include/asm-generic/barebox.lds.h to make this branch work. Would be
good if you could give your patches at least *some* testing.

I've no armv7 availlable work fine
I test it on at91 and s3c and versatile work fine
but no mmu yet
and I compiled all ARM

did'nt see the missing KEEP as I'm working on a really small version of
barebox with nothing inside to go done to less than 26K
