[coreboot] Lenovo N20p Chromebook

[John Lewis]

Hello,

I've purchased the subject Chromebook with a view to getting some sort 
of custom ROM going for Baytrail based Chromebooks, and I have my first 
brick of the day.

I'm using ChromeOS coreboot and the firmware-clapper-5218.B branch. As 
per the advice Aaron gave me regarding the ASUS C200 some time ago, I 
extracted the reference code binary and changed line 111 in 
src/arch/x86/Makefile.inc as follows:

$(CBFSTOOL) $@.tmp add -f $(CONFIG_REFCODE_BLOB_FILE) -n 
$(CONFIG_CBFS_PREFIX)/refcode -t raw

Other than that I had to place vboot_api.h from the same branch of 
ChromeOS vboot_reference in the src directory to get compile to 
complete, but have left the ChromeOS stuff in for the time being. My 
.config is attached. Any pointers?

Thanks,

John.
