Yes. Steven provides some wiki pages for it.

MCB will be combined to single bin file. The problem is that the platform uses the bin file from output IA32 or X64 
directory instead of the module output directory. Binary cache is for the module output directory. 
I suggest to update the platform to consume the module output file. But, I meet with one tool issue to support 
RAW FILE type, because Microcode uses RAW file type. BZ https://bugzilla.tianocore.org/show_bug.cgi?id=1765 is submitted. 
I suggest to fix this tool issue first. 

> 2) .inc might be text file, instead of binary. How can we support that?
.inc is similar to .c source file. Its output is .mcb, then be combined to .bin file. .bin file will be cached. 
.inc is not required to be cached. On next build, build tool will compare the hash value of source file, if 
hash value is not changed. Previous cached .bin file will be used.
