+Bayley Bay CRB
+==============
+
+This uses as FSP as with Crown Bay, except it is for the Atom E3800 series.
+Download this and get the .fd file (BAYTRAIL_FSP_GOLD_003_16-SEP-2014.fd at
+the time of writing). Put it in the corresponding board directory and rename
+it to fsp.bin.
+
+Obtain the VGA RAM (Vga.dat at the time of writing) and put it into the same
+board directory as vga.bin.
+
+You still need two more binary blobs. For Bayley Bay, they can be extracted
+from the sample SPI image provided in the FSP (SPI.bin at the time of writing)::
+
+ $ ./tools/ifdtool -x BayleyBay/SPI.bin
+ $ cp flashregion_0_flashdescriptor.bin board/intel/bayleybay/descriptor.bin
+ $ cp flashregion_2_intel_me.bin board/intel/bayleybay/me.bin
+
+Now you can build U-Boot and obtain u-boot.rom::
+
+ $ make bayleybay_defconfig
+ $ make all
+
+Note that the debug version of the FSP is bigger in size. If this version
+is used, CONFIG_FSP_ADDR needs to be configured to 0xfffb0000 instead of
+the default value 0xfffc0000.
