[POWERPC] bootwrapper: Use physical address in PHDR for uImage

2008-04-16T21:46:14+00:00

Now that we properly set the physical address in the program header of the
vmlinux ELF we can extract it to properly set the load and entry point for
u-boot uImages.  Before we always hard coded the load & entry point to 0.
However there are situations that the kernel may be built with a non-zero
physical address.

We use objdump to extract the PHDR.  We assume that there is only one
PHDR in the vmlinux of type LOAD.

[POWERPC] bootwrapper: Add a firmware-independent simpleboot target.

2008-04-03T01:36:11+00:00

This target produces a flat binary rather than an ELF file,
fixes the entry point at the beginning of the image, and takes
a complete device tree with no fixups needed.

[POWERPC] PS3: Bootwrapper improvements

2008-04-01T09:43:07+00:00

Improve the debugging support of the PS3 bootwraper code:

 o Increase the size of the PS3 bootwrapper overlay from 256 to 512 bytes to
   allow for more debugging code in the overlay.
 o Use the dot symbol to set the size of __system_reset_overlay.  The
   assembler will then emit an error if the overlay code is too big.
 o Remove some unused instructions.
 o Update the text describing the PS3 bootwrapper overlay.
 o Add a check for null pointer writes.
 o Change hcall return value from s64.

[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.

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.
