NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__. All common C compilers pre-define the same macros to signal which architecture the code is being compiled for: __arm__ for AArch32 (or earlier versions) and __aarch64__ for AArch64. There's no need for TF-A to define its own custom macros for this. In order to unify code with the export headers (which use __aarch64__ to avoid another dependency), let's deprecate the AARCH32 and AARCH64 macros and switch the code base over to the pre-defined standard macro. (Since it is somewhat unintuitive that __arm__ only means AArch32, let's standardize on only using __aarch64__.)

* 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.
