TrustZone is orthogonal to secure boot. It's close to functionality to SGX, trying to allow for some SecureElement-like functionality on the main SoC (in which you can do crypto, DRM, etc).

I think trustzone is mostly used for drm these days, SE has its own dedicated security processor on Qualcomm and (iirc) Huawei socs
