Florent Kermarrec 9a7f9cb87b build/generic_programmer: catch 404 not found when downloading config/proxy. 2020-05-05 12:16:29 +02:00
Florent Kermarrec d0b8daa005 build/platform: allow doing a loose lookup_request (return None instead of ConstraintError) and allow subname in lookup_request. 
In the platforms, insead of doing:
self.lookup_request("eth_clocks").rx
we can now do:
self.lookup_request("eth_clocks:rx")

This allows some try/except simplifications on constraints.

Florent Kermarrec b8f9f83a8f build/openocd: add find_config method to allow using local config file or download it if not available locally. 2020-05-05 09:56:13 +02:00
Florent Kermarrec 9bef218ad6 cpu/microwatt: fix integration/crt0.S (thanks Benjamin Herrenschmidt).

Franck Jullien bc5a1986e2 bios: add terminal history 
Terminal history and characters parsing is done in readline.c.
Passing TERM_NO_HIST disable terminal history.
Passing TERM_MINI use a simple terminal implementation in order to save
more space.

Franck Jullien e764eabda1 builder: add a parameter to pass options to BIOS Makefile 2020-05-01 12:10:50 +02:00
Florent Kermarrec bb70a2325a cpu/software: move CPU specific software from the BIOS to the CPU directories. 
This simplifies the integration of the CPUs' software, avoid complex switches in the code,
and is a first step to make CPUs fully pluggable.

The CPU name is no longer present in the crt0 files (for example crt0-vexriscv-ctr.o
becomes crt0-ctr.o) so users building firmwares externally will have to update their
Makefiles to remove the $(CPU) from crt0-$(CPU)-ctr.o.
