The imx51 lowlevel setup code currently sets the full cpu
speed only for TO3. It turned out that this is not a TO
specific hack but a hack for older babbage boards. Move
the lowlevel init after babbage_power_init() so that we
can remove the hack from the generic i.MX51 lowlevel
function. As this potentially changes the UART clock we
have to flush the console beforehand and call the clock
notifier afterwards.

Traditionally U-Boot and barebox have the exception vectors at
the start of the binary. There is no real reason in doing so,
because in the majority of cases this data will not be at 0x0
where it could be used as vectors directly anyway.
This patch puts the vectors into a separate linker section and
defines an head function which is placed at the start of the
image instead. Putting this in a separate function also has
the advantage that it can be placed at the start of images
which require an additional header like several Freescale i.MX
images. As the head function contains the barebox arm magic
those images can now also be detected as barebox images.

Keep frequency multiplier enabled to be able to do a warmstart
The wachtdog's reset does only reset the ARM core, not the whole silicon.
But the PLLs seems to do some strange things: It seems they switch back to
the low frequency reference when the watchdog barks. But in the case the
frequency multiplier is off (not used due to 26 MHz reference usage) the
machine stops, because the PLLs are stopping due to the lack of a reference
frequency. As the power on reset will set the FPM_EN bit again, a power cycle
brings the machine back to life.
By keeping the frequency multiplier enabled, also a warmstart triggered by the
watchdog can restart the machine now.

When booting from NAND, its important to know the correct page size. When
the NAND is used as the boot source, four dedicated pins are used to configure
the correct page size and address cycles. These pins can be read back in one
of the NFC registers to parametrize the load function.
This patch also extends the read routine to support more than four address
cycles on demand.
BTW: At least some mini2440s are misconfigured to use five address cycles for
a NAND device that is known to need only four address cycles. In this case the
vendor is at our side: This NAND simply ignores any additional address cycles
than required.

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.

Also, put the LCD_CS pin in the same mode as the kernel does to
prevent flickering.

With this patch barebox can now be booted from RAM, NOR and NAND on the
mini2440 platform. 'CONFIG_S3C24XX_NAND_BOOT' must still be 'y' to be able to
boot from NAND.

The default configuration of the mini2440 in the current 2.6.37 kernel uses
a flash based BBT. So, the barebox for the mini2440 must also use one, to be
in sync with the kernel about bad blocks in the flash.
Due to the used OOB layout, the generic BBT description coming with the
framework can be used.

This is required in order to enable booting from NAND and using the generic

Two types of SDRAM devices are known to be shipped by FriendlyARM. This config
should work on both of them. But it is really tested only for the HY57V561620
type.

we use the board revision to specify to the linux kernel the type of lcd
we use. So we can have only one machine for those 3 boards:
- sam9m10-ekes (LG)
- sam9g45-ekes (LG)
- sam9m10g45-ek (Truly)
today we support 2 lcds model:
- LG philips LB043WQ1
- Truly TFT1N4633-E
by default we select the Truly as the sam9m10g45-ek is the most common board
