-/**
- * @defgroup ARM7 ARM7
- * @details ARM7 port for the GCC compiler.
- *
- * @section ARM7_INTRO Introduction
- * The ARM7-GCC port supports the ARM7 code in the following three modes:
- * - Pure ARM mode, this is the preferred mode for code speed. The code size
- * is larger however. This mode is enabled when all the modules are compiled
- * in ARM mode, see the Makefiles.
- * - Pure THUMB mode, this is the preferred mode for code size. In this mode
- * the execution speed is slower than the ARM mode. This mode is enabled
- * when all the modules are compiled in THUMB mode, see the Makefiles.
- * - Interworking mode, when in the system there are ARM modules mixed with
- * THUMB modules then the interworking compiler option is enabled. This is
- * usually the slowest mode and the code size is not as good as in pure
- * THUMB mode.
- * .
- * @section ARM7_STATES Mapping of the System States in the ARM7 port
- * The ChibiOS/RT logical system states are mapped as follow in the ARM7
- * 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, usually the CPU goes through several
- * hardware states during the startup phase.
- * - <b>Normal</b>. This is the state the system has after executing
- * @p chSysInit(). In this state the ARM7TDMI has both the interrupt sources
- * (IRQ and FIQ) enabled and is running in ARM System Mode.
- * - <b>Suspended</b>. In this state the IRQ sources are disabled but the FIQ
- * sources are served, the core is running in ARM System Mode.
- * - <b>Disabled</b>. Both the IRQ and FIQ sources are disabled, the core is
- * running in ARM System Mode.
- * - <b>Sleep</b>. The ARM7 code does not have any built-in low power mode but
- * there are clock stop modes implemented in custom ways by the various
- * silicon vendors. This state is implemented in each microcontroller support
- * code in a different way, the core is running (or freezed...) in ARM
- * System Mode.
- * - <b>S-Locked</b>. IRQ sources disabled, core running in ARM System Mode.
- * - <b>I-Locked</b>. IRQ sources disabled, core running in ARM IRQ Mode. Note
- * that this state is not different from the SRI state in this port, the
- * @p chSysLockI() and @p chSysUnlockI() APIs do nothing (still use them in
- * order to formally change state because this may change).
- * - <b>Serving Regular Interrupt</b>. IRQ sources disabled, core running in
- * ARM IRQ Mode. See also the I-Locked state.
- * - <b>Serving Fast Interrupt</b>. IRQ and FIQ sources disabled, core running
- * in ARM FIQ Mode.
- * - <b>Serving Non-Maskable Interrupt</b>. There are no asynchronous NMI
- * sources in ARM7 architecture but synchronous SVC, ABT and UND exception
- * handlers can be seen as belonging to this category.
- * - <b>Halted</b>. Implemented as an infinite loop after disabling both IRQ
- * and FIQ sources. The ARM state is whatever the processor was running when
- * @p chSysHalt() was invoked.
- * .
- * @section ARM7_NOTES The ARM7 port notes
- * The ARM7 port is organized as follow:
- * - The @p main() function is invoked in system mode.
- * - Each thread has a private user/system stack, the system has a single
- * interrupt stack where all the interrupts are processed.
- * - The threads are started in system mode.
- * - The threads code can run in system mode or user mode, however the
- * code running in user mode cannot invoke the ChibiOS/RT APIs directly
- * because privileged instructions are used inside.<br>
- * The kernel APIs can be eventually invoked by using a SWI entry point
- * that handles the switch in system mode and the return in user mode.
- * - Other modes are not preempt-able because the system code assumes the
- * threads running in system mode. When running in supervisor or other
- * modes make sure that the interrupts are globally disabled.
- * - Interrupts nesting is not supported in the ARM7 code because their
- * implementation, even if possible, is not really efficient in this
- * architecture.
- * - FIQ sources can preempt the kernel (by design) so it is not possible to
- * invoke the kernel APIs from inside a FIQ handler. FIQ handlers are not
- * affected by the kernel activity so there is not added jitter.
- * .
- * @section ARM7_IH ARM7 Interrupt Handlers
- * ARM7 Interrupt handlers do not save function-saved registers so you need to
- * make sure your code saves them or does not use them (this happens
- * because in the ARM7 port all the OS interrupt handler functions are declared
- * naked).<br>
- * Function-trashed registers (R0-R3, R12, LR, SR) are saved/restored by the
- * system macros @p CH_IRQ_PROLOGUE() and @p CH_IRQ_EPILOGUE().<br>
- * The easiest way to ensure this is to just invoke a normal function from
- * within the interrupt handler, the function code will save all the required
- * registers.<br>
- * Example:
- * @code
- * CH_IRQ_HANDLER(irq_handler) {
- * CH_IRQ_PROLOGUE();
- *
- * serve_interrupt();
- *
- * VICVectAddr = 0; // This is LPC214x-specific.
- * CH_IRQ_EPILOGUE();
- * }
- * @endcode
- * This is not a bug but an implementation choice, this solution allows to
- * have interrupt handlers compiled in thumb mode without have to use an
- * interworking mode (the mode switch is hidden in the macros), this
- * greatly improves code efficiency and size. You can look at the serial
- * driver for real examples of interrupt handlers.<br>
- * It is important that the serve_interrupt() interrupt function is not
- * inlined by the compiler into the ISR or the code could still modify
- * the unsaved registers, this can be accomplished using GCC by adding
- * the attribute "noinline" to the function:
- * @code
- * #if defined(__GNUC__)
- * __attribute__((noinline))
- * #endif
- * static void serve_interrupt(void) {
- * }
- * @endcode
- * Note that several commercial compilers support a GNU-like functions
- * attribute mechanism.<br>
- * Alternative ways are to use an appropriate pragma directive or disable
- * inlining optimizations in the modules containing the interrupt handlers.

-/**
- * @defgroup ARM7_CONF Configuration Options
- * @details ARM7 specific configuration options. The ARM7 port allows some
- * architecture-specific configurations settings that can be overridden by
- * redefining them in @p chconf.h. Usually there is no need to change the
- * default values.
- * - @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 practice this value is the stack space used by the chSchDoReschedule()
- * stack frame.<br>
- * This value can be affected by a variety of external things like compiler
- * version, compiler options, kernel settings (speed/size) and so on.<br>
- * The default for this value is @p 0x10 which should be a safe value, you
- * can trim this down by defining the macro externally. This would save
- * some valuable RAM space for each thread present in the system.<br>
- * The default value is set into <b>./os/ports/GCC/ARM7/chcore.h</b>.
- * - @p IDLE_THREAD_STACK_SIZE, stack area size to be assigned to the IDLE
- * thread. Usually there is no need to change this value unless inserting
- * code in the IDLE thread hook macro.

-/**
- * @defgroup ARM7_STARTUP Startup Support
- * @details ARM7 startup code support. ChibiOS/RT provides its own generic
- * startup file for the ARM7 port. Of course it is not mandatory to use it
- * but care should be taken about the startup phase details.
- *
- * @section ARM7_STARTUP_1 Startup Process
- * The startup process, as implemented, is the following:
- * -# The 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.
- * -# The ARM state is switched to System with both IRQ and FIQ sources
- * disabled.
- * -# 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.
- * -# 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.
- * .
- * @section ARM7_STARTUP_2 Expected linker symbols
- * 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 __und_stack_size__ Undefined Instruction stack size.
- * - @p __abt_stack_size__ Memory Abort stack size.
- * - @p __fiq_stack_size__ FIQ service stack size.
- * - @p __irq_stack_size__ IRQ service stack size.
- * - @p __svc_stack_size__ SVC service stack size.
- * - @p __sys_stack_size__ System/User 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.
