[U-Boot] [PATCH 3/4][v3] powerpc/85xx:Make debug exception vector accessible

2012-03-26 Thread Prabhakar Kushwaha
Debugging of e500 and e500v1 processer requires debug exception vecter (IVPR + IVOR15) to have valid and fetchable OP code. While executing in translated space (AS=1), whenever a debug exception is generated, the MSR[DS/IS] gets cleared i.e. AS=0 and the processor tries to fetch an instruction fro
