Would like to get a solution for this and see 2 ways to go in imx-base.inc:

1. allow thumb:
<snip>
# Float-Point setting
# handled by software
# DEFAULTTUNE_mx6 ?= "cortexa9t-neon"
# handled by hardware
DEFAULTTUNE_mx6 ?= "cortexa9thf-neon"
</snip>

2. if thumb2 is not allowed (why?):
<snip>
# Float-Point setting
# handled by software
# DEFAULTTUNE_mx6 ?= "cortexa9-neon"
# handled by hardware
DEFAULTTUNE_mx6 ?= "cortexa9hf-neon"
ARM_INSTRUCTION_SET = "arm"
</snip>

Opinions?
