The function names do not make it clear what return value
is expected and do not save a single line of code. Put
the code inline and unbreak the wrong checks introduced
with a3c1e5d888.

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.

These CPUs are called "i.MX", but they are of type STM378x from SigmaTel. They
do not share any devices with the other i.MX CPUs, so we need a separate
architecute directory to handle them without an ifdef hell in the native i.MX
files.

Adding MCI card support for S3C2440 CPUs. This is for reference only, as there
is currently no user in the barebox tree. Maybe one with access to the A9M2440
development kit can check it on his/her system.
Checked here with my own S3C2440 based system which is not in the barebox tree.

Makes the internal boot source configurable.
Also changes section names slightly so that .flash_header_0x1000 isn't
matched to .flash_header_0x100* etc.

AT91sam9g20 is an evolution of the at91sam9260 with a faster clock
speed.
We created a new board for this device but based the chip support
directly on 9260 files with little updates.
