Could I use Cortex-A for embedded applications?

Have you considered a 300MHz Cortex M7 from Atmel?

ATSAME70 and ATSAMV7x devices also have CAN interfaces etc.

Combines MCU and DSP functionality offering similar performance to entry level 32bit DSP's.

Also one of the applications it is targeting is Motor control.

Cortex-As have more powerful DSP instructions becuase of SIMD and NEON
Still Performance/price of Cortex-As are higher than Cortex-Ms.
