Move baytrail & fsp_baytrail to the common IFD interface.
- Add the common/firmware subdir to the baytrail & fsp_baytrail makefiles and remove the code it replaces. - Update baytrail & fsp_baytrail Kconfigs to use the common code. - Update the IFD Kconfig help and prompts for the TXE vs ME. - Whittle away at the CBFS_SIZE defaults. All the fsp_baytrail platforms have their own defaults.

- The Intel processor in the selected system requires a special firmware
- for an integrated controller called Management Engine (ME). The ME
- firmware might be provided in coreboot's 3rdparty/blobs repository. If
- not and if you don't have the firmware elsewhere, you can still
- build coreboot without it. In this case however, you'll have to make

- If you don't have an Intel Firmware Descriptor (ifd.bin) for your
- board, you can select this option and coreboot will build without it.
- Though, the resulting coreboot.rom will not contain all parts required
- to get coreboot running on your board. You can however write only the
- BIOS section to your board's flash ROM and keep the other sections
- untouched. Unfortunately the current version of flashrom doesn't
- support this yet. But there is a patch pending [1].
-
- WARNING: Never write a complete coreboot.rom to your flash ROM if it
- was built with a fake IFD. It just won't work.
