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.

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.

On i.MX we enable all necessary clocks during startup of the clock
controller driver, so we do not need the register hacking in the drivers
anymore.

- increased the region size for OMAP3, as it was not correct
- decrease region size for OMAP4 to prevent overlapping.

- for i.MX1 the register is in the System Control unit, so move
the code to arch/arm/mach-imx/imx1.c

of_alias_get_id() returns the number of the gpio bank, so we have
to multiply with 32 to get the gpio base.

All i.MX SoCs now use the same imx_silicon_revision() function to get
the revision. Add a separate header file for it and a common function
used on all SoCs.

We called create_sections with 4096MB as size argument, but create_sections
expected the argument in bytes, so create sections was completely optimized
away due to the size >>= 20. This patch changes the size argument to be in
megabytes and adjusts map_cachable to pass the argument in megabytes.

We can't do anything useful in the error function, so we just hang.
This has the advantage that at least when a JTAG debugger is connected
we can see what happens. Otherwise the code just jumps to NULL in case
of an error.

The old clock support is now unused. Remove it. The former i.MX clko
command is superseeded by generic clock manipulation commands.
