David Gibson b610b9780b [POWERPC] Don't use HOSTCFLAGS in BOOTCFLAGS
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.

This zImage is really just the stripped vmlinux, but it means that there

David Gibson 988519acb3 [POWERPC] Fix compiler/assembler flags for Ebony platform boot files
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.

Josh Boyer 60e417536b [POWERPC] Pass per-file CFLAGs for platform specific op codes
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.

Mark A. Greer c368d921da [POWERPC] Add bootwrapper support for Motorola PrPMC2800 platform
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or
PrPMC2800 baseboard, respectively.  There are several variants of each
type of processor module which can have different amounts of memory,
amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362.

The bootwrapper code for that platform reads VPD from an I2C EEPROM
to determine the processor module variant.  From the variant, the
amount of memory, etc. is determined and the device tree is updated
accordingly.  If the variant cannot be determined (e.g., corrupted
VPD or a previously unknown variant), the property values already
in the device tree are used.

Also, the firmware for those platforms does not completely configure
the mv64x60 host bridge so that configuration is done here.

Mark A. Greer ae4b3fbc7a [POWERPC] Add bootwrapper support for Marvell/mv64x60 I2C
Some platforms support a variety processor modules with no method of
determining which exact processor module is being used except by
examining Vital Product Data (VPD).  The modules may have different
amounts of memory, clock frequencies, etc. so reading the VPD becomes
necessary to correctly set properties in the device tree before its
passed to the kernel.

Often the VPD is stored in I2C EEPROMs so an I2C driver becomes necessary.
This I2C driver is for the I2C controller that's embedded on the Marvel
mv64x60 line of host bridges.

Mark A. Greer 0f81b11d2a [POWERPC] Add bootwrapper support for Marvell/mv64x60 hostbridge
The mv64x60 host bridge has many windows between its various components
(cpu, system memory, ethernet ctlr, MPSC, DMA ctlr, PCI MEM, PCI I/O).
Unfortunately, the firmware on some of mv64x60-based platforms do not
properly or completely configure those windows (e.g., MPSC->system memory
windows not configured or CPU->PCI MEM space not configured).

So, the missing configuration needs to be done in either the bootwrapper
or in the kernel.  To keep the kernel as clean as possible, it is done
in the bootwrapper.  Note that I/O controller configuration is NOT being
done, its only the windows to allow the I/O controllers and other components
to access memory, etc. that is being done--drivers assume that their
controllers can already access system memory).

Table of routines and the windows they configure:
	mv64x60_config_ctlr_windows()	ENET->System Memory
					MPSC->System Memory
					IDMA->System Memory

	mv64x60_config_pci_windows()	PCI MEM->System Memory
					PCI I/O->Bridge's Registers

Mark A. Greer 916066d591 [POWERPC] Add Makefile rules to wrap dts file in zImage
Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically
compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file.
The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and
arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively.

Having separate rules allows the user to choose whether to include a device
tree--and which device tree--at build time.  This is useful when one Makefile
target builds a zImage that runs on several platforms except for differing
device trees.  By just setting CONFIG_DEVICE_TREE and running "make zImage.dts"
the exact zImage you want is built without Makefile bloat or manually running
the wrapper script.

The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE)

David Gibson d25a9d66e0 [POWERPC] Fix some missing build dependencies in arch/powerpc/boot
This patch fixes a couple of missing dependencies in
arch/powerpc/boot/Makefile.  First, it ensures that the zlib.h header
is linked in before attempting to build gunzip_util.o, as it is,
building gunzip_util.o usually works, but not always depending on make
order.

Second, it makes the final images which are built using a dts
dependent on that dts, so the image will be correctly rebuilt if the
dts changes.  This in turn requires fixing the definition of the dts
variable.  CONFIG_DEVICE_TREE from Kconfig will have quotes around it,
which don't matter when passing the variable to a shell, but which
need to be removed when incorporating it into a filename for make's
use.

David Gibson cd197ffcf1 [POWERPC] zImage: Cleanup and improve zImage entry point
This patch re-organises the way the zImage wrapper code is entered, to
allow more flexibility on platforms with unusual entry conditions.
After this patch, a platform .o file has two options:

1) It can define a _zimage_start, in which case the platform code gets
   control from the very beginning of execution.  In this case the
   platform code is responsible for relocating the zImage if necessary,
   clearing the BSS, performing any platform specific initialization, and
   finally calling start() to load and enter the kernel.

2) It can define platform_init().  In this case the generic crt0.S
   handles initial entry, and calls platform_init() before calling
   start().  The signature of platform_init() is changed, however, to
   take up to 5 parameters (in r3..r7) as they come from the platform's
   initial loader, instead of a fixed set of parameters based on OF's
   usage.

   When using the generic crt0.S, the platform .o can optionally
   supply a custom stack to use, using the BSS_STACK() macro.  If this
   is not supplied, the crt0.S will assume that the loader has
   supplied a usable stack.

In either case, the platform code communicates information to the
generic code (specifically, a PROM pointer for OF systems, and/or an
initrd image address supplied by the bootloader) via a global
structure "loader_info".

In addition the wrapper script is rearranged to ensure that the
platform .o is always linked first.  This means that platforms where
the zImage entry point is at a fixed address or offset, rather than
being encoded in the binary header can be supported using option (1).

David Gibson ad9d2716cf [POWERPC] zImage: Add more flexible gunzip convenience functions
At present, arch/powerpc/boot/main.c includes a gunzip() function
which is a convenient wrapper around zlib.  However, it doesn't
conveniently allow decompressing part of an image to one location,
then the remainder to a different address.

This patch adds a new set of more flexible convenience wrappers around
zlib, moving them to their own file, gunzip_util.c, in the process.
These wrappers allow decompressing sections of the compressed image to
different locations.  In addition, they transparently handle
uncompressed data, avoiding special case code to handle uncompressed
vmlinux images.

The patch also converts main.c to use the new wrappers, using the new
flexibility to avoid decompressing the vmlinux's ELF header twice as
we did previously.  That in turn means we avoid extending our
allocations for the vmlinux to allow space for the extra copy of the
ELF header.

of the corresponding node.  When the flat dt is edited/moved, the node
pointers in the phandle table are updated accordingly so no phandles kept
by the caller become stale.

Geoff Levand 020533ef24 [POWERPC] cell: fix default zImage build target
Change CONFIG_PPC_CELL to CONFIG_PPC_IBM_CELL_BLADE in the powerpc boot
makefile.

CONFIG_PPC_CELL is used to build the generic cell processor support, and
is not an indication of platform.

Michael Ellerman dcf9065122 [POWERPC] Fix boot wrapper invocation if CROSS_COMPILE contains spaces
My CROSS_COMPILE is "ccache /opt/compilers/blah", which confuses
the boot wrapper script. Quote CROSS_COMPILE and CROSS32_COMPILE
so they can safely contain spaces.

Andrew Morton 5b9b5572c8 [PATCH] git-powerpc: wrapper: don't require execute permissions
If you lose the x bit (eg: by using patch(1)), powerpc won't build.  Be
defensive about it...

Paul Mackerras 2bf118197c [POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot
This puts the knowledge of how to create various sorts of zImage
wrappers into a script called "wrapper" that could be used outside of
the kernel tree.  This changes arch/powerpc/boot so it first builds
the files that the wrapper script needs, then runs it to create
whatever flavours of zImage are required.

This version does uImages as well.  The zImage names are changed
slightly; zImage.pseries is the one with the PT_NOTE program header
entry added, and zImage.pmac is the one without.  If the
zImage.pseries gets made, it will also get hardlinked to zImage;
otherwise, if zImage.pmac is made, it gets hardlinked to zImage.

Mark A. Greer b2c5f61920 [POWERPC] Start arch/powerpc/boot code reorganization
This abstracts the operations used in the bootwrapper, and defines
the operations needed for the bootwrapper to run on an OF platform.

The operations have been divided up into platform ops (platform_ops),
firmware ops (fw_ops), device tree ops (dt_ops), and console ops
(console_ops).

The proper operations will be hooked up at runtime to provide the
functionality that you need.

Niels Kristian Bech Jensen fda7ffd25f [POWERPC] Add -fno-stack-protector to BOOTCFLAGS in arch/powerpc/boot/Makefile.
I got some undefined references to __stack_chk_fail in
arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying
to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing
Protection.

This patch adds -fno-stack-protector to BOOTCFLAGS in
arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and
not CFLAGS?).

Niels Kristian Bech Jensen
