The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.

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

Add a helper function for boards to register their memory
devices. This makes the board code smaller and also helps
getting rid of map_base and struct memory_platform_data.
And switch all of the memory to it

we keep struct memory_platform_data for now on we will switch off the memories
resources to struct resource

Often enough the exception vectors are not on TEXT_BASE (for example
on i.MX SoCs in internal boot mode), so the board specific code did
not map the exception vectors to 0x0 but whatever happens to be on
TEXT_BASE. Also, the current section-only mapping requires the
exception vectors to be on a 1MB boundary.
Instead, create the possibility to create second level tables and
use this to map a copy of the exception vectors in a board
independent way.

With the change to Hz as the main clock unit on the STM architecture the
Chumby must also use this unit.

The ChumbyOne boot from MCI card only. As ist more fun to run barebox with
a persistant environment, provide one in the second partition on the MCI card.

The so called "chumby one" aka falconwing is an i.MX23 based platform.
Note: This is work in progress. Use with care.
