powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

ppc: Export tlb_44x_hwater for KVM

2008-04-27T15:21:37+00:00

PowerPC 440 KVM needs to know how many TLB entries are used for the host kernel linear mapping (it does not modify these mappings when switching between guest and host execution). Signed-off-by: Hollis Blanchard Acked-by: Josh Boyer Acked-by: Paul Mackerras Signed-off-by: Avi Kivity

[POWERPC] Move phys_addr_t definition into asm/types.h

2008-04-16T21:46:14+00:00

Moved phys_addr_t out of mmu-*.h and into asm/types.h so we can use it in places that before would have caused recursive includes. For example to use phys_addr_t in we would have included which would have possibly included which includes . Wheeee recursive include. CONFIG_PHYS_64BIT is a bit counterintuitive in light of ppc64 systems and thus the config option is only used for ppc32 systems with >32-bit physical addresses (44x, 85xx, 745x, etc.).

[POWERPC] Remove fixup_bigphys_addr() for arch/powerpc to avoid link error

2007-05-17T11:11:13+00:00

There are no actual implementations of fixup_bigphys_addr() in arch/powerpc, and with a 64-bit aware ioremap() and so forth, it should no longer be necessary. This patch removes the last dregs of fixup_bigphys_addr() from arch/powerpc. In fact, the only reason this hasn't caused link errors already is that nobody must have tried using one of the small number of drivers using io_remap_pfn_range() on one of the small number of platforms which are 32-bit but define CONFIG_PHYS_64BIT. Nonetheless this fixes a bug, and should go into 2.6.22. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] Early serial debug support for PPC44x

2007-05-08T04:47:33+00:00

This adds support for early serial debugging via the built in port on IBM/AMCC PowerPC 44x CPUs. It uses a bolted TLB entry in address space 1 for the UART's mapping, allowing robust debugging both before and after the initialization of the MMU.

[POWERPC] Revise PPC44x MMU code for arch/powerpc

2007-05-02T10:04:29+00:00

This patch takes the definitions for the PPC44x MMU (a software loaded TLB) from asm-ppc/mmu.h, cleans them up of things no longer necessary in arch/powerpc and puts them in a new asm-powerpc/mmu_44x.h file. It also substantially simplifies arch/powerpc/mm/44x_mmu.c and makes a couple of small fixes necessary for the 44x MMU code to build and work properly in arch/powerpc.
