[ARM] move include/asm-arm to arch/arm/include/asm

2008-08-02T20:32:35Z

Move platform independent header files to arch/arm/include/asm, leaving those in asm/arch* and asm/plat* alone. Signed-off-by: Russell King

Cleanup asm/{elf,page,user}.h: #ifdef KERNEL is no longer needed

2008-02-07T16:42:30Z

asm/elf.h, asm/page.h and asm/user.h don't export to userspace now, so we can drop #ifdef __KERNEL__ for them. [k.shutemov@gmail.com: remove #ifdef __KERNEL_] Signed-off-by: Kirill A.

[ARM] 4496/1: elf_hwcap: fix up #include misplacement

2007-07-20T20:29:18Z

While bisecting an iop13xx compile failure I noticed that include/asm-arm/hwcap.h should be included from include/asm-arm/elf.h outside #ifndef __ASSEMBLY__ since hwcap.h has its own __ASSEMBLY__ protections. Cc: Catalin Marinas Signed-off-by: Dan Williams Signed-off-by: Russell King

[ARM] 4473/2: Take the HWCAP definitions out of the elf.h file

2007-07-12T15:20:15Z

The patch moves the HWCAP definitions and the extern elf_hwcap declaration to the hwcap.h header file. Signed-off-by: Catalin Marinas Signed-off-by: Russell King

[ARM] 4054/1: ep93xx: add HWCAP_CRUNCH

2006-12-18T00:14:54Z

Add HWCAP_CRUNCH so that the dynamic linker knows whether it can use Crunch-optimised libraries or not. Signed-off-by: Lennert Buytenhek Signed-off-by: Russell King

[ARM] 3881/4: xscale: clean up cp0/cp1 handling

2006-12-03T17:52:22Z

XScale cores either have a DSP coprocessor (which contains a single 40 bit accumulator register), or an iWMMXt coprocessor (which contains eight 64 bit registers.) Because of the small amount of state in the DSP coprocessor, access to the DSP coprocessor (CP0) is always enabled, and DSP context switching is done unconditionally on every task switch. Access to the iWMMXt coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is first issued, and iWMMXt context switching is done lazily. CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will have iWMMXt support', but boards are supposed to select this config symbol by hand, and at least one pxa27x board doesn't get this right, so on that board, proc-xscale.S will incorrectly assume that we have a DSP coprocessor, enable CP0 on boot, and we will then only save the first iWMMXt register (wR0) on context switches, which is Bad. This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on might have iWMMXt support, and we will enable iWMMXt context switching if it does.' This means that with this patch, running a CONFIG_IWMMXT=n kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt state over context switches, and running a CONFIG_IWMMXT=y kernel on a non-iWMMXt capable CPU will still do DSP context save/restore. These changes should make iWMMXt work on PXA3xx, and as a side effect, enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined), as well as setting and using HWCAP_IWMMXT properly.

[ARM] Move HWCAP_* definitions to asm/elf.h

2006-11-30T12:24:46Z

Move HWCAP_* definitions into asm/elf.h, where they should belong. Since userspace wants to get at these definitions by including asm/procinfo.h, include asm/elf.h from this file if __KERNEL__ is not defined, and issue a warning suggesting to fix the program up to use asm/elf.h instead.
