ROM-Code passes boot source information in r4. First stage does likewise
when invoking second stage. When net booting second stage, r4 has no
definite value. Fix this and pass the original boot source along.

This gives us a valid $bootsource value in net booted barebox, which is
important, so the same environment is loaded.

With the addition of 15afd9d25 ("ARM: at91: Add initial support for the
EVB-KSZ9477 eval board"), we now have two multi-image capable boards
supported, but users still have to choose a specific SoC, so they can't
be selected at the same time.

Fix this, by restricting the menu to the non-multi-image configurations,
i.e. CONFIG_ARCH_* symbols become specific to non-multi-image.

The multi-image configurations on the other hand directly select the
CONFIG_SOC_* symbol they require. Existing CONFIG_ARCH_* usage is
adjusted to align with the new usage.

Eventually, we would want to have a at91_multi_defconfig along with
this, but for now leave existing configs as is.

As the at91sam9n12 series includes at91sam9n12, at91sam9cn11,
at91sam9cn12. So, add subtype to distinguish them.

and then register a device

The code is take from linux

drop AT91_BASE_SYS for dbgu

factorise the soc type in the Kconfig but keep the ARCH_ so far
as the device code have the same function accross soc which for now does not
allow us to compile soc together

Here are the at91 specific files dedicated to the at91sam9g45 series. They
mimic the traditional at91 way of managing chips & boards.

The first board that embeds at91sam9g45 chip is the AT91SAM9M10G45-EK. In
the future, we will add the m10 and other boards revisions

this implementation is based on linux one (v2.6.35-rc5-76-gd0c6f62)
it will calculate all the clock dynamically instead of statictly
this will use also the new clock framework

it will also print the clock status after the console init
