2007-12-20[POWERPC] Use embedded dtc in kernel buildsDavid Gibson
This patch alters the kernel makefiles to build dtc from the sources embedded in the previous patch. It also changes the arch/powerpc/boot/wrapper script to use the embedded dtc, rather than expecting a copy of dtc already installed on the system.

2007-12-20[POWERPC] Merge dtc upstream sourceDavid Gibson
This incorporates a copy of dtc into the kernel source, in arch/powerpc/boot/dtc-src. This commit only imports the upstream sources verbatim, a later commit will actually link it into the kernel Makefiles and use the embedded code during the kernel build.

2007-12-20[POWERPC] wrapper: Treat NULL as root node in devp_offset; add ↵Scott Wood
devp_offset_find() Many operations, as currently used in the wrapper, assume they can pass NULL and have it be treated as the root node. However, libfdt-wrapper converts NULL to -1, which is only appropriate when searching for nodes, and will cause an error otherwise.

2007-12-20[POWERPC] wrapper: Rename offset in offset_devp()Scott Wood
fdt_wrapper_create_node passes a variable called offset to offset_devp(), which uses said parameter to initialize a local variable called offset. Due to one of the odder aspects of the C language, the result is an undefined variable, with no error or warning.

2007-12-14[POWERPC] ucc_geth: use rx-clock-name and tx-clock-name device tree propertiesTimur Tabi
Updates the ucc_geth device driver to check the new rx-clock-name and tx-clock-name properties first. If present, it uses the new function qe_clock_source() to obtain the clock source. Otherwise, it checks the deprecated rx-clock and tx-clock properties. Update the device trees for 832x, 836x, and 8568 to contain the new property names only.

2007-12-11[POWERPC] Kill flatdevtree.cDavid Gibson

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.

2007-12-06[POWERPC] Implement 'make bootwrapper_install'David Woodhouse

2007-12-06[POWERPC] Create otheros.bld next to specified output file, not in $object ↵David Woodhouse
directory The bootwrapper script currently generates an 'otheros.bld' file in addition to the file specified by the -o option, when asked to build a wrapper for PS3. It should do that in the same directory as the output, not the directory where the wrapper objects are kept (which might potentially not be writable when the script runs). Arguably, the 'otheros.bld' ought to be created with the filename specified as the -o argument. But that's a more intrusive change.

2007-11-08[POWERPC] bootwrapper: Revert ps3 binary flag usage, and remove .bin suffixScott Wood
The ps3 target produces two images, and the binary one is not the "primary" image that corresponds to the -o flag; thus, it no longer uses the generic binary flag. On platforms which do use the binary flag, it no longer produces a .bin suffix, so that the output file matches what was passed to the -o flag. This should fix the zImage ln problems for the ps3 target.
