Coreboot uses a simple flash-based filesystem called Coreboot Filesystem (CBFS) to organise files used during boot. This allows files to be named and their position in the flash to be set. It has special features for dealing with x86 devices which typically memory-map their SPI flash to the top of 32-bit address space and need a 'boot block' ending there.
Create a library to help create and read CBFS files. This includes a writer class, a reader class and associated other helpers. Only a subset of features are currently supported.
