[POWERPC] Fix building of COFF zImages

2007-06-07T12:21:31+00:00

The COFF zImage (for booting oldworld powermacs) wasn't being built
correctly because the procedure descriptor in crt0.S for the zImage
entry point wasn't declared as .globl, and therefore wasn't getting
pulled in from wrapper.a by the linker.  This adds the necessary
.globl statement.

[POWERPC] Fix zImage.coff generation for 32-bit pmac

2007-06-02T12:26:22+00:00

Commit 9da82a6dee9db4cd5ae7a74ab4f51afb52b6efb9 inadvertently
removed the platform override for zImage.coff to be generated
with pmaccoff.   Rather than add a special makefile rule,
change the platform for which the wrapper platform uses
the special rules.

[POWERPC] Don't use HOSTCFLAGS in BOOTCFLAGS

2007-06-02T11:01:56+00:00

In the bootwrapper code for powerpc, we include HOSTCFLAGS into the
BOOTCFLAGS used for building the zImage wrapper code.  Since the
wrapper code is not host code, this makes no sense.  This patch
removes the use of HOSTCFLAGS here, instead including directly into
BOOTCFLAGS those flags from the normal kernel CFLAGS which also make
sense in the bootwrapper code.

In particular, this makes the bootwrapper use -msoft-float, preventing
the compiler from generating floating point instructions.  Previously,
under some circumstances the compiler could generate floating point
instructions in the bootwrapper which would cause exceptions on
embedded CPUS which don't have floating point support.

[POWERPC] Create a zImage for legacy iSeries

2007-06-02T11:01:56+00:00

This zImage is really just the stripped vmlinux, but it means that there
is one less special case for iSeries and also that the zImages will be
built for a combined kernel build that happens to include iSeries.

This zImage boots fine on legacy iSeries.

[POWERPC] Fix compiler/assembler flags for Ebony platform boot files

2007-06-02T11:01:55+00:00

The recent addition of assembler flags for 44x.c and ebony.c in the
bootwrapper to make them compile on certain toolchains was not correct
and could break other platforms.  This patch switches to using a
compiler flag instead, which implies the appropriate assembler flag,
and also stops the compiler itself generating instructions which are
invalid for the platform in question.

[POWERPC] Pass per-file CFLAGs for platform specific op codes

2007-05-17T11:11:19+00:00

As a result of compiling all of the wrapper files for every platform
now, the kernel build can fail for toolchains that don't support various
op codes by default.  An example of this building a 7xx platform with
the ELD4.0 toolchain, is below:

/tmp/ccYjhJoL.s: Assembler messages:
/tmp/ccYjhJoL.s:42: Error: Unrecognized opcode: `mtdcr'
/tmp/ccYjhJoL.s:43: Error: Unrecognized opcode: `mfdcr'
make[1]: *** [arch/powerpc/boot/44x.o] Error 1

The following patch introduces additional CFLAGS for the 4xx specific
files and fixes the kernel compile.

[POWERPC] Small fixes for the Ebony device tree

2007-05-17T11:11:14+00:00

This patch corrects a number of minor errors in the Ebony device tree:
	- Missing (given as 0) cache sizes are added to the CPU node
	- device_type properties are removed from nodes which don't
have a reasonably well defined device_type binding.  This does require
a very small code change to locate the busses to be probed for
of_platform devices by 'compatible' instead of 'device_type'.
	- A node is added for the SRAM controller
	- The unit address of the small-flash node is adjusted to
correctly reflect the reg property.
	- device_type values for the MAL and ZMII are updated to
reflected more up-to-date versions of the binding.
	- An incorrect offset in the partition map for the large-flash
node is corrected.
	- Some redundant values, already commented out are removed
entirely.

[POWERPC] Fix make rules for treeImage.initrd

2007-05-17T11:11:14+00:00

At present attempting to build treeImage.initrd.* boot images will
fail, because make will select the treeImage.% rule which also matches
instead of the correct and more specific treeImage.initrd.% rule.
This patch corrects the problem by listing the more specific rule
first.
