DDI0100I_ARM_Architecture_Reference_Manual and
DDI0308C_thumb2_supplement are the latest basic documents. To
implement coprocessor instructions which is a plus such as VPF, NEON
and WMMX, you might need the coresponding specs.

Arm-elf is a choice. However, I am not sure whether it supports the
latest ARMv7 and Thumb2 instructions. I think a real ARM target or
QEMU is necessary, otherwise, it's very inconvenient for you to test
and implement the Linux function call handler.

You will need real ARM target or QEMU absolutely.

QEMU is a good choice if you don't have any ARM target. You might need
to contact QEMU guys.
