#include <arch.h>
Sanitise includes across codebase 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&#39;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: e0ea0928d5b7 (&#34;Fix gpio includes of mt8173 platform to avoid collision.&#34;). More recently, this patch has had similar problems: 46f9b2c3a282 (&#34;drivers: add tzc380 support&#34;). This problem was introduced in commit 4ecca33988b9 (&#34;Move include and source files to logical locations&#34;). At that time, there weren&#39;t too many headers so it wasn&#39;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.

switch (mode) {
case CPU_UP:
Fix types of arch.h definitions Define the values as unsigned int or unsigned long long based on the actual size of the register. This prevents subtle issues caused by having a type that is too small. For example: #define OPTION_ENABLE 0x3 #define OPTION_SHIFT 32 uint64_t mask = OPTION_ENABLE &lt;&lt; OPTION_SHIFT; Because OPTION_ENABLE fits in an int, the value is considered an int. This means that, after shifting it 32 places to the left, the final result is 0. The correct way to define the values is: #define OPTION_ENABLE ULL(0x3) #define OPTION_SHIFT U(32) In this case, the compiler is forced to use a 64 bit value from the start, so shifting it 32 places to the left results in the expected value.
