Trusted Firmware currently has no support for secure self-hosted debug. To avoid unexpected exceptions, disable software debug exceptions, other than software breakpoint instruction exceptions, from all exception levels in secure state. This applies to both AArch32 and AArch64 EL3 initialization. Change-Id: Id097e54a6bbcd0ca6a2be930df5d860d8d09e777 Signed-off-by: dp-arm <dimitris.papastamos@arm.com>
On Juno, the secure privileged invasive debug authentication signal (SPIDEN) is controlled by board SCC registers, which by default enable SPIDEN. Disable secure privileged external debug in release builds by programming the appropriate Juno SoC registers.
