As exposed by "make randconfig", we have an issue with the dependencies for BOOTM_OPTEE. This symbol needs to select BOOTM_LINUX and in turn depend on the library symbols that have to be enabled for BOOTM_LINUX to be valid (LIB_BOOTI, LIB_BOOTM and LIB_BOOTZ).

It is typical whenever OP-TEE OS is loaded before U-Boot proper that
|
|
it modifies the FDT passed to U-Boot proper to add reserved-memory
|
|
nodes for the RAM it just reserved for itself.
|
|
|
|
U-Boot must copy those reserved-nodes in the FDT for the next OS to
|
|
boot.
|
|
|
|
Failing to do so will incur random crashes or device reboots once the
|
|
next OS is running.
|
|
|
|
This makes sure that whenever TEE is present in the environment,
|
|
meaning a TEE OS will be part of the boot flow, the copy made by the
|
|
OP-TEE lib will happen.
