ARM: proc: convert v7 proc infos into a common macro · dc939cd8

由 Pawel Moll 提交于 5月 20, 2011

As most of the proc info content is common across all v7
processors, this patch converts existing A9 and generic v7
descriptions into a macro (allowing extra flags in future).

ARM: vfp: add VFPv4 capability detection and populate elf_hwcap · 18b9dc13

由 Will Deacon 提交于 6月 08, 2011

The presence of VFPv4 cannot be detected simply by looking at the FPSID
subarchitecture field, as a value >= 2 signifies the architecture as
VFPv3 or later.

This patch reads from MVFR1 to check whether or not the fused multiply
accumulate instructions are supported. Since these are introduced with
VFPv4, this tells us what we need to know.

ARM: hwcaps: add new HWCAP defines for ARMv7-A · 254cdf8e

由 Will Deacon 提交于 6月 03, 2011

Modern ARMv7-A cores can optionally implement these new hardware
features:

- VFPv4:
    The latest version of the ARMv7 vector floating-point extensions,
    including hardware support for fused multiple accumulate. D16 or D32
    variants may be implemented.

- Integer divide:
    The SDIV and UDIV instructions provide signed and unsigned integer
    division in hardware. When implemented, these instructions may be
    available in either both Thumb and ARM, or Thumb only.

This patch adds new HWCAP defines to describe these new features. The
integer divide capabilities are split into two bits for ARM and Thumb
respectively. Whilst HWCAP_IDIVA should never be set if HWCAP_IDIVT is
clear, separating the bits makes it easier to interpret from userspace.

ARM: hwcaps: use shifts instead of hardcoded constants · 194a7f72

由 Will Deacon 提交于 6月 03, 2011

The HWCAP numbers are defined as constants, each one being a power of 2.
This has become slightly unwieldy now that we have reached 32k.

This patch changes the HWCAP defines to use (1 << n) instead of coding
the constant directly. The values remain unchanged.

  由 Dave Martin 提交于 6月 23, 2011
```
Without this patch, xscale_80200_A0_A1 is missing the
icache_flush_all entry, which would result in the wrong functions
being called at run-time.

This patch re-uses xscale_icache_flush_all for
xscale_80200_A0_A1_cache_fns.
