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

With compressed image support TEXT_BASE will become the base
address of the uncompressed image. What the boards want instead
is the base address of the decompressor code or, if not compressed,
the base address of the uncompressed image. Use _text which is
the correct one for both cases.

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

Changing PLL settings is somehow tricky on the i.MX27: Whenever the clock
speed of the main PLL is changed, the clock stops for about 100 us until the
PLL locks into the new frequency. While this clock stop, also the SDRAM
controller cannot refresh the memory, because it uses the same clock source.
This can lead into data loss and random system crashes.
This patch divides the PLL setting in two steps. First step is to re-program
the PLL and clock settings to values possible at a core supply of 1.25 V.
Second step is to increase the core power supply to 1.45 V and switch the
CPU clock to the specified 400 MHz.

Just a little bit cleanup.

this will allow each arch to handle the boards more simply and depending on
there need
the env var BOARD will refer to the current board dirent
for sandbox as we have only one board the board dirent is arch/sandbox/board
