corebld user space application.

19 | This requires code in the application that is loaded | ||
20 | into Core B. In order to reset, the application needs | ||
21 | to install an interrupt handler for Supplemental | ||
22 | Interrupt 0, that sets RETI to 0xff600000 and writes | ||
23 | bit 11 of SICB_SYSCR when bit 5 of SICA_SYSCR is 0. | ||
24 | This causes Core B to stall when Supplemental Interrupt | ||
25 | 0 is set, and will reset PC to 0xff600000 when | ||
26 | COREB_SRAM_INIT is cleared. | ||
