You have two options when building a BSP: 
(A) download packages + build
(B) git clone + build

(A) is a packaged release according to a stable version and (B) if you want to pick new git commit.

I normally do (B) as follow:

Assuming you are at /home/user/development
# cd /home/user/development
# git clone  git://git.yoctoproject.org/poky.git
# cd /home/user/development/poky
# git checkout -b danny --track origin/danny
# git clone  git://git.yoctoproject.org/meta-intel.git 
# cd /home/user/development /poky/meta-intel
# git checkout -b danny --track origin/danny
# cd /home/user/development
# mkdir build
# cd /home/user/development/build
# source /home/user/development/poky/oe-init-build-env <your-bsp-build-name>
# cd /home/user/development/build/<your-bsp-build-name>
# vi conf/bblayer.bb
 
BBLAYERS ?= " \
  /home/user/development/poky/meta \
  /home/user/development/poky/meta-yocto \
  /home/user/development/poky/meta-yocto-bsp \
  /home/user/development/poky/meta-intel \
  /home/user/development/poky/meta-intel/meta-cedartrail \
  "

# vi conf/local.bb
// uncomment the following
BB_NUMBER_THREADS = "4"
PARALLEL_MAKE = "-j 4"

// add the following line for cedartrail
MACHINE ?= "cedartrail"  
OR
MACHINE ?= "cedartrail-nopvr"
as listed below http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel/tree/meta-cedartrail/conf/machine?h=danny 

# cd /home/user/development/build/<your-bsp-build-name>
# bitbake core-image-sato
