2007-12-11[POWERPC] Use embedded libfdt in the bootwrapperDavid Gibson
This incorporates libfdt (from the source embedded in an earlier commit) into the wrapper.a library used by the bootwrapper. This includes adding a libfdt_env.h file, which the libfdt sources need in order to integrate into the bootwrapper environment, and a libfdt-wrapper.c which provides glue to connect the bootwrapper's abstract device tree callbacks to the libfdt functions. In addition, this changes the various wrapper and platform files to use libfdt functions instead of the older flatdevtree.c library.

Most of these were previously used by numerous C files and redeclared in each one. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-06-14[POWERPC] Consolidate cuboot initialization codeDavid Gibson
The various cuboot platforms (i.e. pre-device tree aware u-boot for 83xx, 85xx and Ebony) share a certain amount of code for parsing the boot parameters. To a certain extent that's inevitable, since they platforms have different definitions of the bd_t structure. However, with some macro work and a helper function, this patch improves the situation a bit. In the process, this fixes a bug on Ebony, which was incorrectly handling the parameters passed form u-boot for the command line (the bug was copied from 83xx and 85xx which have subsequently been fixed).

2007-05-12[POWERPC] U-boot passes the initrd as start/end, not start/size.Scott Wood
The boot wrapper platform init code on 83xx and 85xx using the cuboot platform type was incorrectly assuming that u-boot supplied the size of the initrd, whereas it actually supplies the end address. This fixes it. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-04-27[POWERPC] bootwrapper: cuboot-83xx: Exclude upper 1MB from heap.Scott Wood
The uppermost part of memory is where u-boot puts the stack, so don't include that in the heap. It's not currently causing problems, as the current code allocates from the bottom of the heap, but this will keep things from potentially breaking if a future implementation were to allocate from the top.

2007-04-24[POWERPC] bootwrapper: cuboot for 83xxScott Wood
This adds cuboot support for MPC83xx platforms. A device tree used with this must have linux,stdout-path in /chosen and linux,network-index in any network device nodes that need mac addresses assigned.
