|
* It is possible that the previous booting stage uses same link
|
|
* address as the FW_DYNAMIC firmware. In this case, the relocation
|
|
* lottery mechanism can potentially overwrite the previous booting
|
|
* stage while other HARTs are still running in the previous booting
|
|
* stage leading to boot-time crash. To avoid this boot-time crash,
|
|
* the previous booting stage can specify last HART that will jump
|
|
* to the FW_DYNAMIC firmware as the preferred boot HART.
|
|
*
|
|
* To avoid specifying a preferred boot HART, the previous booting
|
|
* stage can set it to -1UL which will force the FW_DYNAMIC firmware
|
|
* to use the relocation lottery mechanism.
