[POWERPC] Fix build failure for tqm8540 and sbc85xx defconfigs

2008-03-19T23:15:00+00:00

The wrapper script didn't have entries for the TQM8540 board and the
SBC8548 or SBC8560 boards.  I've assumed that the TQM8540 console is
8250 based and not CPM based by looking at its defconfig.  There was
also a trailing * on the TQM8555 entry that I removed too.

[POWERPC] 8xx: Fix wrapper platform for adder875, and combine defconfigs.

2008-03-07T14:42:41+00:00

This fixes the following bug:

Separate defconfigs are no longer needed now that CONFIG_DEVICE_TREE is gone.

[POWERPC] bootwrapper: Build multiple cuImages

2008-02-07T00:40:19+00:00

Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image
with a fdt blob which means for any given configuration only one dts
file can be selected and so support for only one board can be built

This moves the selection of the default .dts file out of the kernel
config and into the bootwrapper makefile.  The makefile chooses which
images to build based on the kernel config and the dts source file
name is taken directly from the image name.  For example "cuImage.ebony"
will use "ebony.dts" as the device tree source file.

In addition, this patch allows a specific image to be requested from the
command line by adding "cuImage.%" and "treeImage.%" targets to the list
of valid built targets in arch/powerpc/Makefile.  This allows the default
dts selection to be overridden.

Another advantage to this change is it allows a single defconfig to be
supplied for all boards using the same chip family and only differing in
the device tree.

Important note: This patch adds two new zImage targets; zImage.dtb.% and
zImage.dtb.initrd.% for zImages with embedded dtb files.  Currently
there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc,
adder875-redboot and ep8248e.  This patch *changes the zImage filenames*
for those platforms.  ie. 'zImage.ps3' is now 'zImage.dtb.ps3'.

This new zImage.dtb targets were added so that the .dts file could be
part of the dependancies list for building them.

[POWERPC] 4xx: EP405 boards support for arch/powerpc

2007-12-23T19:13:14+00:00

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.

[POWERPC] Use embedded dtc in kernel builds

2007-12-20T05:18:00+00:00

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.

[POWERPC] Allow for bootwrapper utilities being in different directory to objects

2007-12-06T03:44:30+00:00

It's possible that the executables which are built as helpers for the
bootwrapper stuff might end up in a different place to the intermediate
object files. Handle that.

[POWERPC] Create otheros.bld next to specified output file, not in $object directory

2007-12-06T03:44:30+00:00

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.
