Ian Campbell 73169874a2 tegra124: Reserve secure RAM using MC_SECURITY_CFG{0, 1}_0 ... These registers can be used to prevent non-secure world from accessing a megabyte aligned region of RAM, use them to protect the u-boot secure monitor code. At first I tried to do this from s_init(), however this inexplicably causes u-boot's networking (e.g. DHCP) to fail, while networking under Linux was fine. So instead I have added a new weak arch function protect_secure_section() called from relocate_secure_section() and reserved the region there. This is better overall since it defers the reservation until after the sec vs. non-sec decision (which can be influenced by an envvar) has been made when booting the os.
