- *
- * NOTE: To AVOID DEADLOCK(s), the atomic lock must only be used for atomic

- * Do not attempt to disable interrupts while holding the atomic operations

- * gpio_direction_input() or gpio_direction_output() have already been
- * called to setup the pin direction and to enable the pin function to
- * be gpio. These macros generate the hardware port address based on
- * the assumption that all ports are 32 bits wide (even though we know
- * they are not). This is so we can efficiently turn pin numbers into
- * port addresses without a lookup.
- *
- * These operations must be done in one instruction to prevent clobbering
- * other thread's accesses to the same port.

- *
- * Core file format: The core file is written in such a way that gdb
- * can understand it and provide useful information to the user (under
- * linux we use the `trad-core' bfd, NOT the osf-core). The file contents
- * are as follows:
- *
- * upage: 1 page consisting of a user struct that tells gdb
- * what is present in the file. Directly after this is a
- * copy of the task_struct, which is currently not used by gdb,
- * but it may come in handy at some point. All of the registers
- * are stored as part of the upage. The upage should always be
- * only one page long.
- * data: The data segment follows next. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover
- * the entire range. All of the addresses are rounded in such a way
- * that an integral number of pages is written.
- * stack: We need the stack information in order to get a meaningful
- * backtrace. We need to write the data from usp to
- * current->start_stack, so we round each of these in order to be able
- * to write an integer number of pages.

- * NOTES:
- *
- * The LDSR is a programmable interrupt controller that is written in software.
- * It emulates the behavior of an pic by fielding the interrupts, choosing a
- * victim thread to take the interrupt and forcing that thread to take a context
- * switch to the appropriate interrupt handler.
- *
- * Because traps are treated as just a special class of interrupts, the LDSR
- * also handles the processing of traps.
- *
- * Because we compile Linux both UP and SMP, we need the LDSR to use
- * architectural locking that is not "compiled out" when compiling UP. For now,
- * we use the single atomic bit lock.

- * only the one that gets to the "waking" field first will gate
- * through and acquire the semaphore. The others will go back
- * to sleep.

- *
- * 03/02/96 Jes Sorensen, Andreas Schwab, Roman Hodek:
- * Fixed some nasty bugs, causing some horrible crashes.
- * A: At some points, the sum (%0) was used as
- * length-counter instead of the length counter
- * (%1). Thanks to Roman Hodek for pointing this out.
- * B: GCC seems to mess up if one uses too many
- * data-registers to hold input values and one tries to
- * specify d0 and d1 as scratch registers. Letting gcc choose these
- * registers itself solves the problem.

- * Each I/O port can be configured to operate in one of several
- * functional modes. One of these modes is GPIO, which causes the
- * entire port to function as a GPIO port. Since the various port
- * registers serve the system with other important functions, such as
- * ethernet, serial, USB, etc., it isn't advantageous to set any of
- * the ports to be entirely dedicated for GPIO use. The processor
- * alternatively allows individual bits of a port to be assigned to be
- * used as GPIO independently from the overall port function. This
- * bit-by-bit assignment is selected by setting the corresponding bit
- * in the port's gpio_mask register. When set, the selected bit is
- * then enabled as a GPIO. If the corresponding bit is set in the
- * gpio_ctl register of the port, the bit is configured as a GPIO
- * output. Otherwise, it is an input.
- *
- * NOTE: This driver uses the bit-by-bit GPIO function assignment
- * exclusively and *never* sets the port function registers to the
- * GPIO function.
- *
- * GPIO is not the main function of any of the I/O ports. The port
- * bit widths are variable from one port to the next, determined by
- * the more common I/O functions of the ports. For simplicity, this
- * driver assumes all the ports are 32 bits wide regardless of the
- * real bit width of the port. GPIO bits are numbered from zero to
- * MAX_UBICOM_GPIOS. Within a port, the least significant bit is
- * numbered bit zero, the most significant is bit 31. Since the ports
- * are considered logically contiguous, GPIO #32 is the zeroth bit in
- * port #1, and so on. Due to the hardware definition, there are
- * large gaps in the GPIO numbers representing real pins.
- *
- * NOTE: It is up to the programmer to refer to the processor data
- * sheet to determine which bits in which ports can be accessed and
- * used for GPIO.
