2007-04-27[POWERPC] boot: More verbose gunzip error messageMilton Miller
Change the error message in gunzip_exactly to be more verbose. Besides the identifier being unrelated to the current function name, the user had no indication if the corruption was near the beginning or the end.

2007-04-24[POWERPC] Abolish PHYS_FMT macro from arch/powerpcDavid Gibson
32-bit powerpc systems define a macro, PHYS_FMT, giving a printf format string fragment for displaying physical addresses, since most 32-bit powerpc platforms use 32-bit physical addresses but a few use 64-bit physical addresses. This macro is used in exactly one place, a rare error message, where we can solve the problem more simply by just unconditionally casting the address up to 64-bit quantity before formatting it. This patch does so, meaning that as we bring MMU definitions from asm-ppc over to asm-powerpc, cleaning them up in the process, we don't need to implement this ugly macro (which additionally has a very bad name for something global).

2007-04-24[POWERPC] Cleanup and fix breakage in tlbflush.hDavid Gibson
BenH's commit a741e67969577163a4cfc78d7fd2753219087ef1 in powerpc.git, although (AFAICT) only intended to affect ppc64, also has side-effects which break 44x. I think 40x, 8xx and Freescale Book E are also affected, though I haven't tested them. The problem lies in unconditionally removing flush_tlb_pending() from the versions of flush_tlb_mm(), flush_tlb_range() and flush_tlb_kernel_range() used on ppc64 - which are also used the embedded platforms mentioned above. The patch below cleans up the convoluted #ifdef logic in tlbflush.h, in the process restoring the necessary flushes for the software TLB platforms. There are three sets of definitions for the flushing hooks: the software TLB versions (revised to avoid using names which appear to related to TLB batching), the 32-bit hash based versions (external functions) amd the 64-bit hash based versions (which implement batching). It also moves the declaration of update_mmu_cache() to always be in tlbflush.h (previously it was in tlbflush.h except for PPC64, where it was in pgtable.h). Booted on Ebony (440GP) and compiled for 64-bit and 32-bit multiplatform.

2007-04-24[POWERPC] Re-organize Kconfig code for 4xx in arch/powerpcDavid Gibson
Now that we always take a device tree in arch/powerpc, there's no good reason not to allow a single kernel to support multiple embedded 4xx boards - the correct platform code can be selected based on the device tree information. Therefore, this patch re-arranges the 4xx Kconfig code to allow this. In addition we: - use "select" instead of depends to configure the correct config options for specific 4xx CPUs and workarounds, which makes the information about specific boards and CPUs less scattered. - Some old, unused (in arch/powerpc) config options are removed: WANT_EARLY_SERIAL, IBM_OCP, etc. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
