Subject: Cater for preloaded BL33 within plat_get_ns_image_entrypoint()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=48ac1df9460a046f925545bc1c94d93bd3506509;p=project%2Fbcm63xx%2Fatf.git

Cater for preloaded BL33 within plat_get_ns_image_entrypoint()

The PRELOADED_BL33_BASE build option allows to preload a BL33 and bypass its
loading by BL2. In ARM standard platforms, the conditional behaviour of
PRELOADED_BL33_BASE is moved within the implementation of
`plat_get_ns_image_entrypoint()` so that all callers may benefit from this
feature.
