Description
Adds RISC-V 32-bit Embedded extension support. The Embedded or "E" extension proposes a reduced register set (down to 16 from 32) to prioritize interrupt and contact switching speed [1].
Test Steps
Flashed to SiFive HiFive1 Rev B with JTAG header as covered in this page. Note - I did need to have the HiFive board plugged in over USB micro as well.
Blinky demo executed without issue.
