Subject: [PATCH 0/2] ARM: imx: change building of SSI FIQ support for i.MX processors

Patches to fix Thumb2 kernel building and change the dependency for SSI FIQ
support to a more specific option to prevent it from being needlessly built
in the first place on more frugal kernel configurations.

A better solution might be to rewrite the function in Thumb-compatible assembly
but the target processors do not support Thumb2 kernels anyway, and the last
time it was suggested the updated code was nacked by Russell. Since its built
as a side-effect on ARMv6/v7 i.MX processors, these could be considered somewhat
Needful Things(tm) by people wanting Thumb2 kernels based on imx_v6_v7_defconfig
or wanting to remove certain boards from their configs.

Matt Sealey (2):
  ARM: build ssi-fiq.S in ARM mode to prevent CONFIG_THUMB2_KERNEL
    build breakage
  ARM: only build ssi-fiq.S et al if CONFIG_SND_IMX_SOC_PCM_FIQ is
    selected
