out a suitable address to put a XIP stage to. Specifically, you pass it the file (to get its filesize), its filename (as the header has a variable length that depends on it), and the granularity requirement it has to fit in (for XIP). The granularity is MTRR-style: when you request 0x10000, cbfstool looks for a suitable place in a 64kb-aligned 64kb block. cbfstool simply prints out a hex value which is the start address of a suitably located free memory block. That value can then be used with cbfs add-stage to store the file in the ROM image. It's a two-step operation (instead of being merged into cbfs add-stage) because the image must be linked twice: First, with some bogus, but safe base address (eg. 0) to figure out the target address (based on file size). Then a second time at the target address. The work flow is: - link file - cbfstool locate - link file again - cbfstool add-stage.
