On porting the v1.3.0-rc1 u-boot, i get a peculiar issue. The board does not reset on giving the 'reset' command. This is observed only on the release candidate version of u-boot. I've also ported the 1.2.0 release and there it works fine. I tried debugging the issue by putting some debug statements, in the board.c file after the init_sequence, and what i observe is that the msr register is getting cleared. But the 1.2.0 version shows the correct value, i.e 0x1200 which is programmed in the start.S. After setting the MSR[DE] bit in the do_reset function along with the DBCR0 register settings, the board resets correctly. Am i missing something. Please throw some light on it. -- sughosh
