Separate BL functions out of arch.h Move the BL function prototypes out of arch.h and into the appropriate header files to allow more efficient header file inclusion. Create new BL private header files where there is no sensible existing header file. Change-Id: I45f3e10b72b5d835254a6f25a5e47cf4cfb274c3

Add support for BL2 in XIP memory In some use-cases BL2 will be stored in eXecute In Place (XIP) memory, like BL1. In these use-cases, it is necessary to initialize the RW sections in RAM, while leaving the RO sections in place. This patch enable this use-case with a new build option, BL2_IN_XIP_MEM. For now, this option is only supported when BL2_AT_EL3 is 1. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>

Changes for new version of image loading in BL1/BL2 This patch adds changes in BL1 & BL2 to use new version of image loading to load the BL images. Following are the changes in BL1: -Use new version of load_auth_image() to load BL2 -Modified `bl1_init_bl2_mem_layout()` to remove using `reserve_mem()` and to calculate `bl2_mem_layout`. `bl2_mem_layout` calculation now assumes that BL1 RW data is at the top of the bl1_mem_layout, which is more restrictive than the previous BL1 behaviour. Following are the changes in BL2: -The `bl2_main.c` is refactored and all the functions for loading BLxx images are now moved to `bl2_image_load.c` `bl2_main.c` now calls a top level `bl2_load_images()` to load all the images that are applicable in BL2. -Added new file `bl2_image_load_v2.c` that uses new version of image loading to load the BL images in BL2. All the above changes are conditionally compiled using the `LOAD_IMAGE_V2` flag. Change-Id: Ic6dcde5a484495bdc05526d9121c59fa50c1bf23
