-+ * current->brk to pick up all of the user variables, plus any memory

-+ * Because we compile Linux both UP and SMP, we need the LDSR to use

-+ * Each I/O port can be configured to operate in one of several

-+ * 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

-+ * 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

-+ * port #1, and so on. Due to the hardware definition, there are
-+ * large gaps in the GPIO numbers representing real pins.
