+ * The ChibiOS/RT logical @ref system_states are mapped as follow in the ARM
+ * Cortex-Mx port:
+ * - <b>Init</b>. This state is represented by the startup code and the
+ * initialization code before @p chSysInit() is executed. It has not a
+ * special hardware state associated.
+ * - <b>Normal</b>. This is the state the system has after executing
+ * @p chSysInit(). In this state the ARM Cortex-Mx has the BASEPRI register
+ * set at @p CORTEX_BASEPRI_USER level, interrupts are not masked. The
+ * processor is running in thread-privileged mode.
+ * - <b>Suspended</b>. In this state the interrupt sources are not globally
+ * masked but the BASEPRI register is set to @p CORTEX_BASEPRI_KERNEL thus
+ * masking any interrupt source with lower or equal priority. The processor
+ * is running in thread-privileged mode.
+ * - <b>Disabled</b>. Interrupt sources are globally masked. The processor
+ * is running in thread-privileged mode.
+ * - <b>Sleep</b>. This state is entered with the execution of the specific
+ * instruction @p <b>wfi</b>.
+ * - <b>S-Locked</b>. In this state the interrupt sources are not globally
+ * masked but the BASEPRI register is set to @p CORTEX_BASEPRI_KERNEL thus
+ * masking any interrupt source with lower or equal priority. The processor
+ * is running in thread-privileged mode.
+ * - <b>I-Locked</b>. In this state the interrupt sources are not globally
+ * masked but the BASEPRI register is set to @p CORTEX_BASEPRI_KERNEL thus
+ * masking any interrupt source with lower or equal priority. The processor
+ * is running in exception-privileged mode.
+ * - <b>Serving Regular Interrupt</b>. In this state the interrupt sources are
+ * not globally masked but only interrupts with higher priority can preempt
+ * the current handler. The processor is running in exception-privileged mode.
+ * - <b>Serving Fast Interrupt</b>. It is basically the same of the SRI state
+ * but it is not possible to switch to the I-Locked state because fast
+ * interrupts can preempt the kernel critical zone.
+ * - <b>Serving Non-Maskable Interrupt</b>. The Cortex-Mx has a specific
+ * asynchronous NMI vector and several synchronous fault vectors that can
+ * be considered to be in this category.
+ * - <b>Halted</b>. Implemented as an infinite loop after globally masking all
+ * the maskable interrupt sources. The ARM state is whatever the processor
+ * was running when @p chSysHalt() was invoked.
+ * .
+ * @section ARMCMx_NOTES The ARM Cortex-Mx port notes
+ * The ARM Cortex-Mx port is organized as follow:
+ * - The @p main() function is invoked in thread-privileged mode.
+ * - Each thread has a private process stack, the system has a single main
+ * stack where all the interrupts and exceptions are processed.
+ * - Only the 4 MSb of the priority level are used, the 4 LSb are assumed
+ * to be zero.
+ * - The threads are started in thread-privileged mode with BASEPRI level
+ * 0x00 (disabled).
+ * - The kernel raises its BASEPRI level to @p CORTEX_BASEPRI_KERNEL in order
+ * to protect the kernel data structures.
+ * - Interrupt nesting and the other advanced NVIC features are supported.
+ * - The SVC instruction and vector, with parameter #0, is internally used
+ * for commanded context switching.<br>
+ * It is possible to share the SVC handler at the cost of slower context
+ * switching.
+ * - The PendSV vector is internally used for preemption context switching.

+ * @defgroup ARMCMx_CONF Configuration Options
+ * @brief ARM Cortex-Mx Configuration Options.
+ * @details The ARMCMx port allows some architecture-specific configurations
+ * settings that can be specified externally, as example on the compiler
+ * command line:
+ * - @p INT_REQUIRED_STACK, this value represent the amount of stack space used
+ * by an interrupt handler between the @p extctx and @p intctx
+ * structures.<br>
+ * In the current implementation this value is guaranteed to be zero so
+ * there is no need to modify this value unless changes are done at the
+ * interrupts handling code.
+ * - @p CORTEX_BASEPRI_USER, this is the @p BASEPRI value for the user threads.
+ * The default value is @p 0 (disabled).<br>
+ * Usually there is no need to change this value, please refer to the
+ * Cortex-Mx technical reference manual for a detailed description.
+ * - @p CORTEX_BASEPRI_KERNEL, this is the @p BASEPRI value for the kernel lock
+ * code.<br>
+ * Code running at higher priority levels must not invoke any OS API.<br>
+ * Usually there is no need to change this value, please refer to the
+ * Cortex-Mx technical reference manual for a detailed description.
+ * - @p ENABLE_WFI_IDLE, if set to @p 1 enables the use of the @p <b>wfi</b>
+ * instruction from within the idle loop. This is defaulted to 0 because
+ * it can create problems with some debuggers. Setting this option to 1
+ * reduces the system power requirements.

+ * @defgroup ARMCMx_STARTUP Startup Support
+ * @brief ARM Cortex-Mx startup code support.
+ * @details ChibiOS/RT provides its own generic startup file for the ARM
+ * Cortex-Mx port.
+ * Of course it is not mandatory to use it but care should be taken about the
+ * startup phase details.
+ *
+ * <h2>Startup Process</h2>
+ * The startup process, as implemented, is the following:
+ * -# Interrupts are masked globally.
+ * -# The two stacks are initialized by assigning them the sizes defined in the
+ * linker script (usually named @p ch.ld). Stack areas are allocated from
+ * the highest RAM location downward.
+ * -# An early initialization routine @p hwinit0 is invoked, if the symbol is
+ * not defined then an empty default routine is executed (weak symbol).
+ * -# DATA and BSS segments are initialized.
+ * -# The CPU state is switched to Privileged and the PSP stack is used.
+ * -# A late initialization routine @p hwinit1 is invoked, if the symbol not
+ * defined then an empty default routine is executed (weak symbol).<br>
+ * This late initialization function is also the proper place for a
+ * @a bootloader, if your application requires one.
+ * -# The @p main() function is invoked with the parameters @p argc and @p argv
+ * set to zero.
+ * -# Should the @p main() function return a branch is performed to the weak
+ * symbol MainExitHandler. The default code is an endless empty loop.
+ * .
+ * <h2>Expected linker symbols</h2>
+ * The startup code starts at the symbol @p ResetHandler and expects the
+ * following symbols to be defined in the linker script:
+ * - @p __ram_end__ RAM end location +1.
+ * - @p __main_stack_size__ Exception stack size.
+ * - @p __process_stack_size__ Process stack size. This is the stack area used
+ * by the @p main() function.
+ * - @p _textdata address of the data segment source read only data.
+ * - @p _data data segment start location.
+ * - @p _edata data segment end location +1.
+ * - @p _bss_start BSS start location.
+ * - @p _bss_end BSS end location +1.
+ * .
