Martin Jansa c417736aca arch-armv7a.inc, tune-arm920t.inc: Fix PACKAGE_EXTRA_ARCHS
* each DEFAULTTUNE with thumb enabled should list it's arm variants in
  PACKAGE_EXTRA_ARCHS, otherwise packages which force arm ISA won't be
  found in do_rootfs
* armv7athf-neon-vfpv4 was missing its own PACKAGE_ARCH and also the arm
  variant

  • Initial Revision

The ARM architecture definitions are split among a number of files. The primary definitions for the variables are handled by the core arch-arm.inc file.

TUNE_ARCH is set to either "arm" or "armeb" depending on the value of the existence of the "bigendian" feature in a given tune.

A small set of ARM specific variables have been defined to allow TUNE_PKGARCH to be automatically defined. Optimized tunings must NOT change the definiton of TUNE_PKGARCH. TUNE_PKGACH_tune- will be ignored. The format of the package arch is enforced by the TUNE_PKGARCH default. The format must be of the form: [t][e][hf][b][-vfp][-neon]

TUNE_PKGARCH is defined as: ${ARMPKGARCH}${ARMPKGSFX_THUMB}${ARMPKGSFX_DSP}${ARMPKGSFX_EABI}${ARMPKGSFX_ENDIAN}${ARMPKGSFX_FPU}

ARMPKGARCH - This is the core package arch component specified by each tuning. This is the primary identifier of a tuning. Usual values are: arm, armv4, armv5, armv6, armv7a, etc.

ARMPKGSFX_THUMB - This is the thumb specific suffix. Curently it is defined in feature-arm-thumb.inc.

ARMPKGSFX_DSP - This is the DSP specific suffix. Currently this is set to 'e' when on armv5 and the dsp feature is enabled.

ARMPKGSFX_EABI - This is the eabi specific suffix. There are currently two defined ABIs specificed, standard EABI and Hard Float (VFP) EABI.
When the callconvention-hard is enabled, "hf" is specified, otherwise it is blank.

ARMPKGSFX_ENDIAN - This is the endian specific suffix. It is defined in the core arch-arm.inc file.

ARMPKGSFX_FPU - This is the FPU specific suffix. The suffix indicates specific FPU optimizations. 'vfp' and 'neon' are both defined.
