hw: enable SMP for ARM Cortex A9 This commit enables multi-processing for all Cortex A9 SoCs we currently support. Moreover, it thereby enables the L2 cache for i.MX6 that was not enabled until now. However, the QEMU variants hw_pbxa9 and hw_zynq still only use 1 core, because the busy cpu synchronization used when initializing multiple Cortex A9 cores leads to horrible boot times on QEMU. During this work the CPU initialization in general was reworked. From now on lots of hardware specifics were put into the 'spec' specific files, some generic hook functions and abstractions thereby were eliminated. This results to more lean implementations for instance on non-SMP platforms, or in the x86 case where cache maintainance is a non-issue. Due to the fact that memory/cache coherency and SMP are closely coupled on ARM Cortex A9 this commit combines so different aspects. Fix #1312 Fix #1807

Introduce 'spec' subdirectories to outline aspects Instead of holding SPEC-variable dependent files and directories inline within the repository structure, move them into 'spec' subdirectories at the corresponding levels, e.g.: repos/base/include/spec repos/base/mk/spec repos/base/lib/mk/spec repos/base/src/core/spec ... Moreover, this commit removes the 'platform' directories. That term was used in an overloaded sense. All SPEC-relative 'platform' directories are now named 'spec'. Other files, like for instance those related to the kernel/architecture specific startup library, where moved from 'platform' directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

hw: use kernel timer for timer driver * Adds public timeout syscalls to kernel API * Kernel::timeout installs a timeout and binds a signal context to it that shall trigger once the timeout expired * With Kernel::timeout_max_us, one can get the maximum installable timeout * Kernel::timeout_age_us returns the time that has passed since the calling threads last timeout installation * Removes all device specific back-ends for the base-hw timer driver and implements a generic back-end taht uses the kernel timeout API * Adds assertions about the kernel timer frequency that originate from the requirements of the the kernel timeout API and adjusts all timers accordingly by using the their internal dividers * Introduces the Kernel::Clock class. As member of each Kernel::Cpu object it combines the management of the timer of the CPU with a timeout scheduler. Not only the timeout API uses the timeout scheduler but also the CPUs job scheduler for installing scheduling timeouts. * Introduces the Kernel::time_t type for timer tic values and values inherited from timer tics (like microseconds).
