6.6.11 C-Boot ROM Boot Status
Apart from the health status discussed in
CTOMBOOTSTS register bits 15:0.
Value
0 C_BOOTROM_BOOTSTS_CTOM_IGNORE
1 C_BOOTROM_BOOTSTS_CTOM_CONTROL_SYSTEM
_START_BOOT
2 C_BOOTROM_BOOTSTS_CTOM_CONTROL_SYSTEM
_READY
3 C_BOOTROM_BOOTSTS_CTOM_BOOT_CMD_ACK
4 C_BOOTROM_BOOTSTS_CTOM_BOOT_CMD_NAK_S
TATUS_NOT_SUPPORTED
5 C_BOOTROM_BOOTSTS_CTOM_BOOT_CMD_NAK_S
TATUS_BUSY_WITH_BOOT
Master subsystem applications should look for this status before sending any IPC command to C-Boot
ROM. For ex: if MTOCIPCBOOTSTS ==
C_BOOTROM_BOOTSTS_CTOM_CONTROL_SYSTEM_READY, it means that C-Boot ROM is ready to
accept MTOC IPC commands.

Description
Invalid status - tells corresponding system that control
system has not filled in a valid value yet
Tells master system that Control system has started to
boot, but not completed the boot process yet
Tells the master system that Control system has
completed the boot and is running. It is ready to accept
IPC commands from the master.
Tells the master system that C-BootROM ACKs the
command in the MTOCBOOTMODE register
Tells the master system that C-BootROM doesn't support
the command in the MTOCBOOTMODE register
Tells the master system that C-BootROM NAKs the
current boot command in the MTOCBOOTMODE
register, as it is already busy with boot.
