This patch fixes two issues in the set_r5_reset function. 1. When in split mode, the lpd_amba_rst bit should only be set when both r5 cpu cores are in reset. Otherwise, if one r5 core is still running, setting the lpd_amba_rst bit will cause an error for the running core. The set_r5_reset function has been modified to check if the other r5 core is still running before setting the lpd_amba_rst bit. 2. The cpu_disable function was always assuming that the r5 cores are in split mode when resetting either core 4 or 5. This is incorrect for lockstep functionality. This patch adds a function check_r5_mode to handle the cpu_disable function correctly for the r5 cores by checking the mode and handling the reset appropriately.
