Paul,
Here's my take on the current status of the patchset:
[POWERPC] bootwrapper: Allow specifying of image physical offset
reworked to look at PHDR (needs linker script update patch). Still
open question on how best to do that (objdump, readelf, C program,
suggestions)
[POWERPC] Remove Kconfig option BOOT_LOAD
should be acceptable.
[POWERPC] Provide access to arch/powerpc include path on ppc64
should be acceptable (desired by others).
[POWERPC] Remove and replace uses of PPC_MEMSTART with memstart_addr
You had some questions about _stext and the PAGE_OFFSET vs
KERNELBASE. Not sure if you are satisfied with the answers.
[POWERPC] Introduce lowmem_end_addr to distiguish from total_lowmem
No comments. Should be straight forward.
[POWERPC] 85xx: Cleanup TLB initialization
Only effects 85xx and I don't have issues with it :)
[POWERPC] Use lowmem_end_addr to limit lmb allocations on ppc32
No comments. Straight forward patch.
[POWERPC] Rename __initial_memory_limit to __initial_memory_limit_addr
No comments. Straight forward patch.
[POWERPC] Clean up some linker and symbol usage
No comments. Straight forward patch.
[POWERPC] Move phys_addr_t definition into asm/types.h
I had an open question if the Kconfig for PHYS_64BIT should get set on
PPC64 as well (has not effect).
I reworked the asm/types.h bits to look like:
+#if defined(CONFIG_PPC64) || defined(CONFIG_PHYS_64BIT)
+typedef __u64 phys_addr_t;
+#else
+typedef __u32 phys_addr_t;
+#endif
[POWERPC] 85xx: Add support for relocatble kernel (and booting at non-
zero
Should probably get a bit more review.
[POWERPC] Update linker script to properly set physical addresses
You felt LOAD_OFFSET should be (CONFIG_PAGE_OFFSET -
CONFIG_PHYSICAL_START). I disagreed. We need to resolve.
I think we should be able to quickly resolve and get into powerpc-next
all but the '85xx: Add support for relocatable kernel' and
'bootwrapper: Allow specifying of image..' patches. If we can close
on the phys_addr_t and linker script patches that would be great.
thanks
- k
