/*
* The following constants identify the extents of the code & read-only data
* regions. These addresses are used by the MMU setup code and therefore they
* must be page-aligned.
*
* When the code and read-only data are mapped as a single atomic section
* (i.e. when SEPARATE_CODE_AND_RODATA=0) then we treat the whole section as
* code by specifying the read-only data section as empty.
*
* BL1 is different than the other images in the sense that its read-write data
* originally lives in Trusted ROM and needs to be relocated in Trusted SRAM at
* run-time. Therefore, the read-write data in ROM can be mapped with the same
* memory attributes as the read-only data region. For this reason, BL1 uses
* different macros.
*
* Note that BL1_ROM_END is not necessarily aligned on a page boundary as it
* just points to the end of BL1's actual content in Trusted ROM. Therefore it
* needs to be rounded up to the next page size in order to map the whole last
* page of it with the right memory attributes.
