      AArch32: Common changes needed for BL1/BL2 · 1a0a3f06
      Yatharth Kochar authored
      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.

      AArch32: Add essential ARM platform and FVP support · 877cf3ff
      Soby Mathew authored
      This patch adds AArch32 support for FVP and implements common platform APIs
      like `plat_get_my_stack`, `plat_set_my_stack`, `plat_my_core_cos` for AArch32.
      Only Multi Processor(MP) implementations of these functions are considered in
      this patch. The ARM Standard platform layer helpers are implemented for
      AArch32 and the common makefiles are modified to cater for both AArch64 and
      AArch32 builds. Compatibility with the deprecated platform API is not
      supported for AArch32.
