2007-12-23[POWERPC] 4xx: Rework clock probing in boot wrapperBenjamin Herrenschmidt7-135/+233
This reworks the boot wrapper library function that probes the chip clocks. Better separate the base function that is used on 440GX,SPe,EP,... from the uart fixups as those need different device-tree path on different processors. Also, rework the function itself based on the arch/ppc code from Eugene Surovegin which I find more readable, and which handles one more bypass case. Also handle the subtle difference between 440EP/EPx and 440SPe/GX, on the former, PerClk is derived from the PLB clock while on the later, it's derived from the OPB.

2007-12-23[POWERPC] 4xx: EP405 boards support for arch/powerpcBenjamin Herrenschmidt7-52/+353
Brings EP405 support to arch/powerpc. The IRQ routing for the CPLD comes from a device-tree property, PCI is working to the point where I can see the video card, USB device, and south bridge. This should work with both EP405 and EP405PC. I've not totally figured out how IRQs are wired on this hardware though, thus at this stage, expect only USB interrupts working, pretty much the same as what arch/ppc did. Also, the flash, nvram, rtc and temp control still have to be wired. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

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.

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.

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 Wood1-6/+7
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.
