ARM: proc: add Cortex-A5 proc info · 15eb169b

Pawel Moll authored May 20, 2011

This patch adds processor info for ARM Ltd. Cortex A5,
which has SCU initialisation procedure identical to A9.

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

Pawel Moll authored May 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

Will Deacon authored Jun 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

Will Deacon authored Jun 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

Will Deacon authored Jun 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.

ARM: mm: proc-xscale: Use new generic struct definition macros · ab1a746d

Dave Martin authored Jun 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.
