* Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now ↵Michael Sevakis2008-04-06
| | | | | | with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16981 a1c6a512-1295-4272-9138-f99709370657
* SPC Codec: Ensure no crash occurs on load failure which could cause ↵Michael Sevakis2008-01-24
| | | | | | emulation to be run without a program loaded on dual core (DSP wasn't initialized yet). The load failures come from core buffering not having the atomic audio file fully loaded before the codec requests the buffer (it gets as many bytes as can be provided) which IMHO isn't very atomic :). Changes in thread execution order after dumping spinlocks for general use simply revealed the buffering race condition. No fix for that will be hacked into the codec itself but should be fixed in the core. Add my copyright to files I had a significant part in developing per request of Adam Gashlin. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16154 a1c6a512-1295-4272-9138-f99709370657
