Soby Mathew 9f3ee61c90 AArch32: Fix the stack alignment issue
The AArch32 Procedure call Standard mandates that the stack must be aligned
to 8 byte boundary at external interfaces. This patch does the required
changes.

This problem was detected when a crash was encountered in
`psci_print_power_domain_map()` while printing 64 bit values. Aligning
the stack to 8 byte boundary resolved the problem.

Fixes ARM-Software/tf-issues#437

Yatharth Kochar 3bdf0e5df2 AArch32: Refactor SP_MIN to support RESET_TO_SP_MIN
This patch uses the `el3_entrypoint_common` macro to initialize
CPU registers, in SP_MIN entrypoint.s file, in both cold and warm
boot path. It also adds conditional compilation, in cold and warm
boot entry path, based on RESET_TO_SP_MIN.

Soby Mathew c11ba852b9 AArch32: add a minimal secure payload (SP_MIN)
This patch adds a minimal AArch32 secure payload SP_MIN. It relies on PSCI
library to initialize the normal world context. It runs in Monitor mode
and uses the runtime service framework to handle SMCs. It is added as
a BL32 component in the Trusted Firmware source tree.
