Cortex a5 doesnt support hardware division such as sdiv and udiv commands. This commit adds a software division function in assembly as well as include appropriate files for software divison. The software division algorithm is a modified version obtained from: http://www.keil.com/support/man/docs/armasm/armasm_dom1359731155623.htm Change-Id: Ib405a330da5f1cea1e68e07e7b520edeef9e2652 Signed-off-by: Usama Arif <usama.arif@arm.com>

The Generic Timer is an optional extension to an ARMv7-A implementation. The generic delay timer can be used from any architecture supported by the Trusted Firmware. In ARMv7 it is needed to check that this feature is present. In ARMv8 it is always present.

ARMv8.2-TTCNP is mandatory from ARMv8.2 onwards, but it can be implemented in CPUs that don't implement all mandatory 8.2 features (and so have to claim to be a lower version). This patch removes usage of the ARM_ARCH_AT_LEAST() macro and uses system ID registers to detect whether it is needed to set the bit or not.

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca339 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

The architecture dependant header files in include/lib/${ARCH} and include/common/${ARCH} have been moved to /include/arch/${ARCH}. Change-Id: I96f30fdb80b191a51448ddf11b1d4a0624c03394 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
