thank you Pedro and Przemek .
I read through the materiel provided but I still have some doubts.
1. Do you know a place where a very beginner coming from TI microcontrolers
(e.g. MSP430 and ARM Cortex M) can learn this embedded linux from the
begining? can you provide a guidance? a series of

Dear garyamort,
Since the book is written for the Linux Kernel version 3.2 and the current
version is 3.8 do you think I will have any problem?

It includes both versions - the examples
2. Why is a DT used to define the HDMI
Because this is a system-on-chip. The HDMI, gpio, gpu, pruss, etc are
all peripherals of the cpu that are located on the chip, but still separate
from the cpu.

DT simplify kernel development for arm processor as they tend to vary on
features, its easier to make a general formula than custom driver for each
processor.

That's a good question---I think the reason is that ARM has much wider
choice of peripherals that tend to be simpler than typical peripherals
on the x86 architecture. On x86, they are usually connected using the
PCI infrastructure, which configures their register and interrupt
layout at boot and
