This hook allows to define a custom way of handling loading an image to SRAM. This can be useful if a system needs to override image loading routines (for example, if a security enclave needs to perform loading and validation) Signed-off-by: Andrei Narkevitch <andrei.narkevitch@analog.com> Signed-off-by: Daniel DeGrasse <daniel.degrasse@analog.com>

this doesn't make sense vs what boot_load_image_to_sram has?

Sorry, not 100% clear here. The intention of this call is that we can hook the SRAM load process to replace the decryption and memory copy routines, for cases where we have custom hardware that handles those routines. Are you saying that the documentation here isn't clear, or that the hook should behave differently?

This should have the same function arguments that the normal function has to allow it to do a variety of different things. Also not sure how this would work loading since you have no information from the image?
