William D. Jones e56f71824d libbase/crt0-picorv32: Emulate support for a relocatable IRQ vector (hardcoded at synthesis time). 2018-11-01 05:02:04 -04:00
William D. Jones f32121e0e1 cpu/picorv32: IRQ vector needs to be moved to 16 bytes after the RESET vector. 2018-11-01 02:23:01 -04:00
William D. Jones 77389d27b5 libbase/crt0-picorv32: Ensure BSS is cleared on boot. 2018-11-01 02:18:03 -04:00
Florent Kermarrec f7969b660a cores/clock: add with_reset parameter (default to True)
In some cases we want to generate the reset externally.

Florent Kermarrec 6048a5291c build/lattice/prjtrellis: modify generated verilog instead of creating a wrapper, handle inouts.
nextpnr expects TRELLIS_IO on all ios, it's not possible to ensure that with a wrapper.
We now just modify the generated verilog to insert the io constraints and TRELLIS_IOs.
