-This is used by a board-independent SPLC780D LCD controller (4 bit mode)
-driver to obtain board-specific information about LCD displays on the board,
-such as the controller register base address and spacing (a function of how
-the address lines are connected on the board) and length of the visible window
-of the display (a function of the LCD panel the controller drives).
-The driver doesnot refer directly to the board-specific header, which therefore is not
-constrained to use macro names consistent with other boards.
-
-!! Must not contain any board-specific macro names (only controller specific) !!
-
-Included at compile-time via an include path specific to the board.
-
-The listed boards contain a single MYTech MOC-16216B-B display driven by
-a Sunplus SPLC870D controller.

- * may produce multiple results (designated as "out" operands
- * in the iclass section) or may have operands used as both
- * inputs and outputs (designated as "inout"). However, the C

- Xilinx ML605 (XT-ML605)
- Xilinx KC705 (XT-KC705)
-
-Interface between board-independent driver and board-specific header.
-
-This is used by a board-independent 16550 UART driver to obtain board-specific
-information about 1 instance of the 16550 UART on the board, such as the device
-register base address and spacing (a function of how the address lines are
-connected on the board) and the frequency of the UART clock. The driver does
-not refer directly to the board-specific header, which therefore is not
-constrained to use macro names consistent with other boards.
-
-!! Must not contain any board-specific macro names (only UART specific). !!
-
-Included at compile-time via an include path specific to the board.
-
-These boards contain a single 16550 UART implemented on the FPGA.
-Their clock frequency comes from the board's core clock (not its own crystal)
-which depends on the core config so is not a constant. Obtained via the BSP.

-/// Enable a specific interrupt, by interrupt number.
-/// The state (enabled vs. disabled) of individual interrupts is global, i.e.
-/// not associated with any specific thread. Depending on system options and
-/// implementation, this state may be stored in one of two ways:
-/// - directly in the INTENABLE register, or
-/// - in a global variable (this is generally the case when INTENABLE is used
-/// not just to control what interrupts are enabled globally, but also for
-/// software interrupt prioritization within an interrupt level, effectively
-/// providing finer grained levels; in this case XOS takes care to update
-/// INTENABLE whenever either the global enabled-state variable or the
-/// per-thread fine-grained-level variable change).
-/// Thus it is best to never access the INTENABLE register directly.
-///
-/// To modify thread-specific interrupt priority level, use one of:
-/// - xos_set_int_pri_level()
-/// - xos_restore_int_pri_level()
-/// - xos_disable_interrupts()
-/// - xos_restore_interrupts()
-///
-/// NOTE: To refer to a specific external interrupt number (BInterrupt pin),
-/// use HAL macro XCHAL_EXTINTx_NUM where 'x' is the external interrupt
-/// number. For example, to enable external interrupt 3 (BInterrupt[3]),
-/// you can use:
-///
-/// xos_interrupt_enable( XCHAL_EXTINT3_NUM );

-/// \param intnum Interrupt number to enable. Must range between 0-31.

-//
-// Along with the save area for each coprocessor, two bitmasks with flags per
-// coprocessor (laid out as in the CPENABLE reg) help manage context switching
-// coprocessors as efficiently as possible:
-//
-// XT_CPENABLE
-// The contents of a non-running thread's CPENABLE register.
-// It represents the coprocessors owned (and whose state is still needed)
-// by the thread. When a thread is preempted, its CPENABLE is saved here.
-// When a thread solicits a context switch, its CPENABLE is cleared - the
-// compiler has saved the (caller-saved) coprocessor state if needed.
-// When a non-running thread loses ownership of a CP, its bit is cleared.
-// When a thread runs, it's XT_CPENABLE is loaded into the CPENABLE reg.
-// Avoids coprocessor exceptions when no change of ownership is needed.
-//
-// XT_CPSTORED
-// A bitmask with the same layout as CPENABLE, a bit per coprocessor.
-// Indicates whether the state of each coprocessor is saved in the state
-// save area. When a thread enters the kernel, only the state of coprocs
-// still enabled in CPENABLE is saved. When the coprocessor exception
-// handler assigns ownership of a coprocessor to a thread, it restores
-// the saved state only if this bit is set, and clears this bit.
-//
-// XT_CP_CS_ST
-// A bitmask with the same layout as CPENABLE, a bit per co-processor.
-// Indicates whether callee-saved state is saved in the state save area.
-// Callee-saved state is saved by itself on a solicited context switch,
-// and restored when needed by the coprocessor exception handler.
-// Unsolicited switches will cause the entire coprocessor to be saved
-// when necessary.
-//
-// XT_NCP_ASA
-// Pointer to aligned save area for non-CP state. This is always filled

-// to be saved then no space is actually allocated and this pointer is
-// not used.

-One thing I noticed is different between my initial idea of stack\r
-assignments to RTC threads, when comparing to interrupts, is that I\r
-expected each RTC thread priority to have its own stack, whereas\r
-interrupts of different priorities share an interrupt stack.\r
-\r
-It's not really a difference in memory usage, because when assigning\r
-multiple priorities to a stack, you have to add-up worst-case for\r
-all priorities. One possible functional difference is that with\r
-separate stacks per priority, it's possible to dynamically change\r
-the priority of an RTC thread (while it's running). Not sure how\r
-valuable that might be -- changing priority is useful with priority\r
-inheritance, to avoid priority inversion, but I don't know how often\r
-an RTC thread might acquire a lock (it couldn't block on acquiring a\r
-lock in the usual sense -- it could get queued waiting and be restarted\r
-when it becomes available, or use try_lock instead of lock).\r

-/// coprocessors, then it should be XOS_STACK_EXTRA_NO_CP

- * size is smaller than 32 bits.
- *
- * Note: XTAV110 bus byte lanes are defined in terms of msbyte and lsbyte
- * relative to the processor. So 32-bit registers are accessed consistently
- * from both big and little endian processors. However, this means byte
- * sequences are not consistent between big and little endian processors.
- * This is fine for RAM, and for ROM if ROM is created for a specific
- * processor (and thus has correct byte sequences). However this may be
- * unexpected for Flash, which might contain a file-system that one wants
- * to use for multiple processor configurations (eg. the Flash might contain
- * the Ethernet card's address, endianness-independent application data, etc).
- * That is, byte sequences written in Flash by a core of a given endianness
- * will be byte-swapped when seen by a core of the other endianness.
- * Someone implementing an endianness-independent Flash file system will
- * likely handle this byte-swapping issue in the Flash driver software.
