powerpc: Fix format string warning in arch/powerpc/boot/main.c

2008-10-31T09:14:19+00:00

Fix format string warning in arch/powerpc/boot/main.c.  Also correct
a typo ("uncomressed") on the same line.

 BOOTCC  arch/powerpc/boot/main.o
arch/powerpc/boot/main.c: In function 'prep_kernel':
arch/powerpc/boot/main.c:65: warning: format '%08x' expects type
'unsigned int', but argument 3 has type 'long unsigned int'

powerpc/boot: Compare _start against ei.loadsize instead ei.memsize

2008-10-21T04:17:47+00:00

If the vmlinux binary in memory is larger than 4 MiB than it collides
with the initial boot code which is linked at 4 MiB in case of cuBoot.
If the the uncompressed image size (on disk size) is less than 4 MiB
then it would fit. The difference between those two sizes is the bss
section. In cuBoot we have the dtb embedded right after the data
section so it is very likely that the reset of the bss section (in
kernel's start up code) will overwrite the dtb blob. Therefore we
reallocate the dtb. Something similar is allready done to the initrd.

[POWERPC] Kill flatdevtree.c

2007-12-11T02:46:15+00:00

Now that earlier patches have switched the bootwrapper to using libfdt
for device tree manipulation, this patch removes the now unused
flatdevtree.c and related files.

[POWERPC] bootwrapper: Move linker symbols into ops.h

2007-08-22T05:27:28+00:00

Most of these were previously used by numerous C files and
redeclared in each one.

[POWERPC] Make kernel_entry_t have global scope in bootwrapper

2007-06-28T09:16:50+00:00

For the convenience of custom platform code make the powerpc
bootwrapper typdef kernel_entry_t global in scope.

[POWERPC] bootwrapper: Decompress less, check more

2007-04-12T17:55:17+00:00

Our kernels put everything in the first load segment, and we read that.
Instead of decompressing to the end of the gzip stream or supplied image
and hoping we get it all, decompress the expected size and complain if
it is not available.

[POWERPC] Move bootwrapper ELF parsing routines to a file

2007-04-12T17:55:16+00:00

The ELF parsing routines local to arch/powerpc/boot/main.c are useful
to other callers therefore move them to their own file.

[POWERPC] Clean up zImage handling of the command line

2007-04-12T17:55:14+00:00

This cleans up how the zImage code manipulates the kernel
command line.  Notable improvements from the old handling:
	- Command line manipulation is consolidated into a new
prep_cmdline() function, rather than being scattered across start()
and some helper functions
	- Less stack space use: we use just a single global command
line buffer, which can be initialized by an external tool as before,
we no longer need another command line sized buffer on the stack.
	- Easier to support platforms whose firmware passes a
commandline, but not a device tree.  Platform code can now point new
loader_info fields to the firmware's command line, rather than having
to do early manipulation of the /chosen bootargs property which may
then be rewritten again by the core.

[POWERPC] Add device tree utility functions to zImage

2007-04-12T17:55:14+00:00

This patch adds a library of useful device tree manipulation functions
to the zImage library, for use by platform code.  These functions are
based on the hooks already in dt_ops, so they're not dependent on a
particular device tree implementation.  This patch also slightly
streamlines the code in main.c using these new functions.

This is a consolidation of my work in this area with Scott Wood's
patches to a very similar end.

[POWERPC] New reg.h for the zImage

2007-03-26T05:11:20+00:00

This patch adds a reg.h to the zImage code, with common definitions
for accessing system registers.  For now, this includes functions for
retrieving the PVR and the stack pointer.  This patch then uses the
new reg.h to let start() display the running stack address without
having to explicitly pass the stack as a parameter from the asm code.
