Yatharth Kochar	1a0a3f0622	AArch32: Common changes needed for BL1/BL2 ... This patch adds common changes to support AArch32 state in BL1 and BL2. Following are the changes: * Added functions for disabling MMU from Secure state. * Added AArch32 specific SMC function. * Added semihosting support. * Added reporting of unhandled exceptions. * Added uniprocessor stack support. * Added `el3_entrypoint_common` macro that can be shared by BL1 and BL32 (SP_MIN) BL stages. The `el3_entrypoint_common` is similar to the AArch64 counterpart with the main difference in the assembly instructions and the registers that are relevant to AArch32 execution state. * Enabled `LOAD_IMAGE_V2` flag in Makefile for `ARCH=aarch32` and added check to make sure that platform has not overridden to disable it.

Soby Mathew	e33b78a658	AArch32: Add support in TF libraries ... This patch adds AArch32 support to cpu ops, context management, per-cpu data and spinlock libraries. The `entrypoint_info` structure is modified to add support for AArch32 register arguments. The CPU operations for AEM generic cpu in AArch32 mode is also added.
