Porting to Intel Atom

[Shailendra Singh]

Hello All,

I am a newbie in coreboot. I just started to port this coreboot to my Intel
Atom laptop.

Below are Some details of my laptop
    Chipset- 945GSE + ICH7
    CPU -  Intel Atom N270 @ 1.60GHz
    Bios Chip- WinBond 25X80AV

I have downloaded the latest source tree of Coreboot for repository.

I have my Host machine configuration as below:
   OS- Federo 10 64 Bit OS
   GCC - 4.3.2
   iASL version - 20061109 [Feb 21 2008]

On one of the discussion topic of this coreboot forum, they suggested that
the mainboard d945gclf is closer to intel Atom for the starting point of
porting to atom.

I started to built the coreboot using following steps
   1. make menuconfig  ( the config file is attached with this mail--*
.config*)
   2. make

I am getting several warnings and at the last getting segmentation fault.
the error log is attached(*coreboot_errorLog.txt*) with this mail.

Any Help is appreciable.

Thanks in advance.

BR,
Shailendra

The d945gclf actually _is_ an intel atom board.

Compiles fine here with r5039

svn co svn://coreboot.org/coreboot/trunk coreboot

for the latest version or

svn co svn://coreboot.org/coreboot/trunk coreboot -r 5039

for a specific revision.

Thanks Joseph,

Now I complied this coreboot  r5039 for intel 945Gclf successfully. Please
let me know how to add support of Intel Atom N270 in cpu/intel/model_106cx.

You need an orange cover NDA with intel, and a few weeks or months of
developer time.

Good luck!

The answer to this question basically means writing the code, so you
will not get much of an answer to this query. If people could easily
add this support then I think it might have been done already, since
the Atom is fairly popular.

If you want to take on the project I think that's great, and it will
be a very welcome contribution to coreboot!

Others who are active in the project are happy to help you when you
run into trouble, but please make sure to ask specific questions, or
it is really impossible to help.

Thanks!
