Inline resetTimer for all platforms - for arm generic timer platforms, we remove resetTimer -> resetGenericTimer indirection and simply include generic_timer.h - this reduces boiler plate for platforms that share timer drivers, as they simply include the one header - there is far more timer code in the RT kernel, which motivates this change

Refactor arm timer ticks calculations - remove a lot of redundancy - define TIMER_CLOCK_HZ for each platform (rather than inconsistenly named variables with inconsist units) - use the common calculation of TIMER_RELOAD

Refactor memory mapped arm timers - make them consistent: struct, type and global vars - typedef the struct definition as volatile - separate struct, typedef and variable definition - always cast the pointer as the timer type

ARM/IRQ: add a function to initialise local IRQ controller for CPUs Similar to initIRQController(), cpu_initLocalIRQController() has to be implemented for each platform. For those that are gonna support SMP, it should be implemented proprely (if required), otherwise it can be stubbed for single core implementations.

Remove many DONT_TRANSLATE markers. The vast majority of the DONT_TRANSLATE markers in the kernel are used to hide __asm__ statements and builtin functions (e.g. __builtin_unreachable ()) from the C-to-Isabelle parser. The parser now supports underscore identifiers and many __asm__ statements, and the builtin functions are prototyped, meaning the vast majority of the DONT_TRANSLATE markers can be dropped. The remaining markers cover functions that must be treated specially.

Store active irq in global variable on kzm The first time the irq number is read from the controller, the interrupt is acknowledged. Subsequent reads of the irq number result in an invalid irq number being read. This modifies the kzm interrupt controller driver to save the current irq number when it's first read from the interrupt controller, preventing the need for future reads from the controller until the next interrupt arrives.

Further separate 'release' and 'verification' builds Originally building the kernel was largely considered to be done in one of two ways 1. Release build with no assertions, no debug symbols and no printing. This was generally considered to be a 'verified' build 2. Debug build with assertions, debug symbols and printing Since then various options were added, such as the 'code injection' option, which we wanted on builds that did not have assertions or other options that affected performance. As such it did not depend upon a debug build and had large warning signs saying that enabling this in a release build would not give you a verified or trusted kernel. Most recently the ability to print from the kernel in release mode was added. For the same reason that tying the ability to print with the performance reduction of various debugging was not always desireable. This change attempts to unify the current state and have a single top level option to enable a 'verification friendly' build. All other options (assertions, printing, code injection) then depend upon this configuration not being set.

ARM: Set the XN bit on kernel mappings that do not need to be executable. This covers the kernel stack, globals frame and device memory. We shouldn't be executing in any of these pages, so functionality should be unaffected. This is primarily a debugging aid.
