AT91sam9g45 series is an ARM 926ej-s SOC family clocked at 400/133MHz.
It embedds USB high speed host and device, LCD, DDR2 RAM, and a full set of
peripherals.
Here is the basic header file support for this product series.

1.5.3.7
Add the at91sam9g45 series support to the AT91 generic clock file.
This takes care of the particularities of the PMC for this series.
It also takes advantage of the management by functionalities of
those PLLs and clocks.

1.5.3.7
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 AT91SAM9G45-EKES. In
the future, the main board for this 9g45 series will be the
AT91SAM9M10G45-EK (I choose this last name for the board file).
Simple drivers are enabled in _devices and board- files. Newer peripheral
support will be added in future patches.
Incuded peripherals support (for now):
- USART
- SPI
- Ethernet
- NAND flash
- LCD
- gpio/joystick/buttons
- leds and pwm

Ah ? Reading SubmittingPatches document, I see in section 6:
"Unless you have a reason NOT to do so, CC [email protected]"
Is posting in "open" and "subscriber only" lists is a reason?

Well, true, it does not. But, have a look at the result, it is so
prettier with those spaces: cpu_is_ directives are aligned.
It's a matter of taste and I considered breaking the rule here was not
so serious...
Thanks Ben.

Can I post this patch series to the patch tracking system or there is
more review to be done (first 3 patches) ?
