On i.MX8QM B0 and i.MX8QXP C0, ROM supports to boot from secondary
container set when either booting from primary container set is failed
or secondary container set has higher SW version.
根据这个帖子的描述，rom 可以在secondary container 拥有更高版本号的时候主动选择secondary container。
我想知道都有哪些芯片支持这个特性，有没有官方文档，我们在调研新机种，需要知道哪些imx8 芯片支持这个特性

it seems this is only for imx8qm/imx8qxp, for other processors, like imx8mp, you can refer to the RM
