setup()

Purpose: The setup() function performs any CPU-specific initialization.

For ARMv6, there is a generic function, armv_setup_v6(), that performs generic ARMv6 initialization:

• checks for VFP (vector floating point) functionality (see the Supporting Vector Floating Point Functionality for ARM Processors technote) and sets the CPU_FLAG_FPU, if necessary
• sets up the MMU for procnto-v6

The armv_setup_v6() function must be called by any CPU-specific setup function for an ARMv6 CPU after it has performed its CPU-specific actions.
