When SPL loading image to secure region, for example, ATF and tee to
DDR secure region. Because the USDHC controller is non-secure master,
it can't access this region and will cause loading issue.
So use a trampoline buffer in non-secure region, then use CPU to copy the
image from trampoline buffer to destination secure region.
There is already common/bouncebuf.c , can you instead implement
something similar, which would behave as a generic bounce buffer, except
for the secure/nonsecure regions ?
The region configuration could come from DT or maybe from firmware ?
