I have been working with the Intel Atom and Yocto Project -
http://www.annabooks.com/Book_OSSATOM.html 

1. Make sure you have first downloaded and extracted Poky. I extract Danny
as - Yocto 1.3/poky-danny-8.0
2. Download the BSP separately and unpack the contents to a temp folder.
There should be a meta-Intel directory.
3. Copy this meta-Intel folder to the Yocto 1.3/poky-danny-8.0 folder. Go
ahead and over write the directory that is there.

Yes, create a new project and build directory. you need to modify the
bblayers.conf file to point to the BSP files:

BBFILES ?= ""
BBLAYERS ?= " \
  /home/user/Yocto1.3/poky-danny-8.0/meta \
  /home/user/Yocto1.3/poky-danny-8.0/meta-yocto \
  /home/user/Yocto1.3/poky-danny-8.0/meta-intel \  
  /home/user/Yocto1.3/poky-danny-8.0/meta-intel/meta-cedartrail \
