# Makefile for making ELF bootable images for booting on CHRP

# using Open Firmware.

# Geert Uytterhoeven September 1997
|
|
|
|
#
|
|
|
|
# Based on coffboot by Paul Mackerras
|
|
|
|
# Simplified for ppc64 by Todd Inglett
|
|
|
|
#
|
|
|
|
# NOTE: this code is built for 32 bit in ELF32 format even though
|
|
|
|
# it packages a 64 bit kernel. We do this to simplify the
|
|
|
|
# bootloader and increase compatibility with OpenFirmware.
|
|
|
|
#
|
|
|
|
# To this end we need to define BOOTCC, etc, as the tools
|
2007-05-29 05:37:12 +00:00
|
|
|
# needed to build the 32 bit image. That's normally the same
|
|
|
|
# compiler for the rest of the kernel, with the -m32 flag added.
|
2005-04-16 22:20:36 +00:00
|
|
|
# To make it easier to setup a cross compiler,
|
|
|
|
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
|
|
|
|
# in the toplevel makefile.

[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).

powerpc: Make the 64-bit kernel as a position-independent executable
This implements CONFIG_RELOCATABLE for 64-bit by making the kernel as
a position-independent executable (PIE) when it is set. This involves
processing the dynamic relocations in the image in the early stages of
booting, even if the kernel is being run at the address it is linked at,
since the linker does not necessarily fill in words in the image for
which there are dynamic relocations. (In fact the linker does fill in
such words for 64-bit executables, though not for 32-bit executables,
so in principle we could avoid calling relocate() entirely when we're
running a 64-bit kernel at the linked address.)
The dynamic relocations are processed by a new function relocate(addr),
where the addr parameter is the virtual address where the image will be
run. In fact we call it twice; once before calling prom_init, and again
when starting the main kernel. This means that reloc_offset() returns
0 in prom_init (since it has been relocated to the address it is running
at), which necessitated a few adjustments.
This also changes __va and __pa to use an equivalent definition that is
simpler. With the relocatable kernel, PAGE_OFFSET and MEMORY_START are
constants (for 64-bit) whereas PHYSICAL_START is a variable (and
KERNELBASE ideally should be too, but isn't yet).
With this, relocatable kernels still copy themselves down to physical
address 0 and run there.
