The KARO Tx53 board in the revision 8030 has an instable SDRAM
setup. It works as long as the MMU is disabled, but the board
crashes at arbitrary places once the MMU gets enabled. So we
need the PLL setup early. Enable it for pbl.

This redefines the sdram controller registers as offsets to the base
rather than as absolute addresses. All users are fixed to use the
SoC specific base address.

as we do not need to probe them and they have no driver or bus attached

We now have request_sdram_region to request a region. Use
it instead of a comparison with MALLOC_BASE.

This was once disabled because we had no board support. This has
changed, so enable the S5P board support in the config so that
the friendlyarm_tiny210_defconfig actually builds for the correct
machine.

board_init_lowlevel is no longer called from generic code, so we can't
just return from in. Instead we have to jump to board_init_lowlevel_return
manually. For the a9m2440 board one case was missed to convert. This
is broken since:

| ARM: give boards control of the reset entry point
|
| On some SoCs (for example AM35xx), the ROM bootloader passes useful
| information in r0 when jumping to barebox.
|
| To avoid overwriting this in the generic reset code, we introduce
| common_reset as a C function and as an assembler macro. This is then
| called form the reset entry point (either in common or in board code).
|
| This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.

Rather than doing this in the SoC specific code just print
it in imx_set_silicon_revision. This saves some lines of code
and also results in i.MX27 now also having the silicon revision
printed during startup.

This moves the known i.MX bootsource settings to a single file
so that the code can be shared. Also we add a enum for the different
boot sources so that it can be used in C Code and not only on the shell.
The pcm038 board is changed to use it instead of digging in the registers
manually.

The check is wrong since it would have to check whether the
new iomem region overlaps with an existing region. Checking
for the base address only is not enough.
Currently this is not possible because every device conflicts
with the top iomem region which covers the whole address space.
This at least fixes the regression that devices whose memory region
begins at 0x0 can no longer be succesfully registered.
