Michael Cardell Widerkrantz	f40987b138	fw: Change license for use with qemu ... This file is also included in at least qemu (GPL-2.0-or-later) besides tillitis-key1 (GPL-2.0-only) and tkey-libs (GPL-2.0-only) so it's licensed as GPL v2 or later even if the rest of the project is -only.	2024-03-19 14:36:31 +01:00
Michael Cardell Widerkrantz	c48724e115	fw: Change memory constants to defines ... Instead of putting memory constant into an enum we use defines. Use the direct memory address instead of ORing constants together to compute the address. An enum in ISO C is a signed int. Some of are memory addresses are to large to fit in a signed int. This is not a problem since we're not using ISO C (-std=gnu99) but it doesn't look very nice if you turn on pedantic warnings. Also, if someone would use another compiler which at least supports the inline assembly we use, but possible not other GNU extensions, things would probably break.	2024-03-19 14:36:20 +01:00

Michael Cardell Widerkrantz	e2bd38c540	fw: Remove unusued forever_redflash() ... Since we now use assert() and feed the CPU an unimplemented instruction we have no need for this.	2024-03-18 16:19:59 +01:00
