The BL images share common stack management code which provides one coherent and one cacheable stack for every CPU. BL1 and BL2 just execute on the primary CPU during boot and do not require the additional CPU stacks. This patch provides separate stack support code for UP and MP images, substantially reducing the RAM usage for BL1 and BL2 for the FVP platform. This patch also provides macros for declaring stacks and calculating stack base addresses to improve consistency where this has to be done in the firmware. The stack allocation source files are now included via platform.mk rather than the common BLx makefiles. This allows each platform to select the appropriate MP/UP stack support for each BL image. Each platform makefile must be updated when including this commit. Fixes ARM-software/tf-issues#76 Change-Id: Ia251f61b8148ffa73eae3f3711f57b1ffebfa632
