Unitialized/unreseted periphery may cause trouble (e.g. firing unwanted interrupts) - Bootloader: Startup now invalidates I/D-Caches at boot +- Bugfix: register bypass with same target register, used for unaligned loads (LWL, LWR), was incorrect. Newlib's memcpy() (MIPS-optimized) uses this. + Consectutive load instructions without nops (which is legal) using same target register like + lw $1, 0(mem) + lwl $1, 1(mem) + or + lwl $1, 0(mem) + lwr $1, 1(mem) + or similar, lead to incorrect result. Now it'S fixed. ----------------------------------------------------------------- Changes in release 11
