remove target

This target is unused, does not support any off the shelf hardware and
has been a maintenance burden for quite some time now.

- *
- * 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.

- * 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.

- * 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
