 Crown Bay CRB
 =============

 U-Boot support of Intel `Crown Bay`_ board relies on a binary blob called
 Firmware Support Package (`FSP`_) to perform all the necessary initialization
 steps as documented in the BIOS Writer Guide, including initialization of the
 CPU, memory controller, chipset and certain bus interfaces.

 Download the Intel FSP for Atom E6xx series and Platform Controller Hub EG20T,
 install it on your host and locate the FSP binary blob. Note this platform
 also requires a Chipset Micro Code (CMC) state machine binary to be present in
 the SPI flash where u-boot.rom resides, and this CMC binary blob can be found
 in this FSP package too.

    * ./FSP/QUEENSBAY_FSP_GOLD_001_20-DECEMBER-2013.fd
    * ./Microcode/C0_22211.BIN

 Rename the first one to fsp.bin and second one to cmc.bin and put them in the
 board directory.

 Note the FSP release version 001 has a bug which could cause random endless
 loop during the FspInit call. This bug was published by Intel although Intel
 did not describe any details. We need manually apply the patch to the FSP
 binary using any hex editor (eg: bvi). Go to the offset 0x1fcd8 of the FSP
 binary, change the following five bytes values from orginally E8 42 FF FF FF
 to B8 00 80 0B 00.

 As for the video ROM, you need manually extract it from the Intel provided
 BIOS for Crown Bay `here`_, using the AMI `MMTool`_. Check PCI option
 ROM ID 8086:4108, extract and save it as vga.bin in the board directory.

 Now you can build U-Boot and obtain u-boot.rom::

    $ make crownbay_defconfig
    $ make all
