Sylvain Munaut be5a53a4fe icE1usb fw: Add GPIO access functions The 32 bit register is split in different fields to speed up access to the 'in' field. The oe/out fields can't be split because all writes are 32 bit wide (i.e. no support for byte enable in the gateware) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Change-Id: Ic25377bb777e5d25939f0e8cfe6b7c6ef8641f6d		2022-01-13 13:21:29 +01:00

Firmware for iCE40 based board
==============================

The icE1usb, icE1usb-proto and e1-tracer boards are running very similar
gateware, all based around a PicoRV32 RISC-V softcore supported by custom
hardware cores to deal with USB and E1.
