This change means that one needs to select _ONE_ cfs implementation at Contiki library link time. But this doesn't appear to be an issue as all platforms have their "favorite" implementation anyway.
- Search target specific directories before CPU specific directories.
- Search CPU specific directories before generic directories.
Note: I checked several builds but nevertheless one or the other might need some additional adjustsments. Sorry for the inconvenience.
- Workarounded the following CTK glitch:
ctk.c calls ctk_arch_keyavail() and ctk_arch_getkey() and needs therefore appropriate declarations (or macros) but it doesn't include a ctk_arch.h or alike to bring those in. So it's necessary to bring those declarations in via contiki-conf.h.
But ctk_arch_getkey() is supposed to return a ctk_arch_key_t - and this typedef'ed in ctk.h which means that ctk.h would need to be included in contiki-conf.h before declaring ctk_arch_getkey().
This IS rather undesirable so the current workaround is to declare ctk_arch_getkey() as returning a char - this is btw done similiar in platform/gtk as well. See ctk/ctk-gtksim.h:
guint ctk_arch_getkey(void);
