This patch adds a dt routine add_dt_overlay_fragment(). This purpose of
which is to encapsulate the dynamic FDT node entries OPTEE provides inside
of a
fragment@0 {
target-path = "/";
__overlay__ {
/* OPTEE nodes go here */
};
};
A subsequent set of patches will wrapper up existing dynamic OPTEE nodes
- /firmware/optee
- /psci
- /reserved/memory
optee@0xaddress
Once done it will be possible for a DTB in memory to be populated
with OPTEE fragments and for a subsequent bootloader to merge the OPTEE
populated overlay into a DTB loaded by a later stage.
if CFG_EXTERNAL_DTB_OVERLAY is not defined then this code has no effect.
