The arm_setup_page_tables() function used to expect a single set of addresses defining the extents of the whole read-only section, code and read-only data mixed up, which was mapped as executable. This patch changes this behaviour. arm_setup_page_tables() now expects 2 separate sets of addresses: - the extents of the code section; - the extents of the read-only data section. The code is mapped as executable, whereas the data is mapped as execute-never. New #defines have been introduced to identify the extents of the code and the read-only data section. Given that all BL images except BL1 share the same memory layout and linker script structure, these #defines are common across these images. The slight memory layout differences in BL1 have been handled by providing values specific to BL1. Note that this patch also affects the Xilinx platform port, which uses the arm_setup_page_tables() function. It has been updated accordingly, such that the memory mappings on this platform are unchanged. This is achieved by passing null values as the extents of the read-only data section so that it is ignored. As a result, the whole read-only section is still mapped as executable. Fixes ARM-software/tf-issues#85 Change-Id: I1f95865c53ce6e253a01286ff56e0aa1161abac5

This patch introduces the arm_setup_page_tables() function to set up page tables on ARM platforms. It replaces the arm_configure_mmu_elx() functions and does the same thing except that it doesn't enable the MMU at the end. The idea is to reduce the amount of per-EL code that is generated by the C preprocessor by splitting the memory regions definitions and page tables creation (which is generic) from the MMU enablement (which is the only per-EL configuration). As a consequence, the call to the enable_mmu_elx() function has been moved up into the plat_arch_setup() hook. Any other ARM standard platforms that use the functions `arm_configure_mmu_elx()` must be updated. Change-Id: I6f12a20ce4e5187b3849a8574aac841a136de83d
