This patch series adds support for device tree blobs to the minimal loader code in boot-wrapper (rendering it not so minimal any more). This is mostly done by borrowing other peoples' code :-) Patch 1 imports the libfdt library for parsing fdt blobs. Patch 2 imports Dave Martin's C code for loading kernel, initrd and fdt via the semihosting ABI Patch 3 drops our assembly implementation of the semihosting loading code in favour of a simple glue layer that calls the C implementation Patch 4 is just a README. New features: * you can pass in an FDT via the --fdt path/to/fdt option * kernels can now be zImage as well as uImage * the 'everything built in' linux-system.axf now supports semihosting command lines too, so you can override the builtin components (eg use the builtin kernel but give it a new command line) The license remains 3-clause BSD because all the new code is compatible with it (Dave Martin's code is 3-clause BSD, and libfdt is dual-licensed GPL/2-clause-BSD).
