Adding a local symbol lets the relocator find local symbols referenced
in relocation records. The local symbol table is erased once the object
module has been loaded.
Specifically the beagleboard, beagleboard xM, beaglebone, beaglebone black.

This commit forms a basic BSP by combining Claas's work with
. new clock and irq code and definitions for
beagle targets (beagleboard and beaglebones), mostly
reused from the Minix codebase, thus making
irqs, ticks and non-polled console mode work too
. new timer code for ns timing with high timer resolution,
24MHz on the AM335X and 13MHz on the DM37XX
. select the console uart based on target at configure time
. removing all the lpc32xx-specific macros and code and
other unused code and definitions that the beagle bsp
was based on
. re-using some standard functions instead of lpc32xx versions
. fixed some whitespace problem in preinstall.am
. fixed some compile warnings
. configure MMU: set 1MB sections directly in the TTBR,
just to show the difference between cacheable RAM and
non-cacheable device memory and invalid ranges; this lets us
turn on caches and not rely on boot loader MMU configuration.
Verified to work when MMU is initially either on or off when
RTEMS gets control.
Thanks for testing, commentary, improvements and fixes to Chris Johns,
Brandon Matthews, Matt Carberry, Romain Bornet, AZ technology and others.

This patch removes functionality for stack checking from
the capture engine and requiresi the use of existing rtems
functions for this information. It modifies ctload to use
functionality similar to rtems cpuusage. It removes the
capture task and stores a new capture task record the first
time the task is seen. The per task data that was still
needed is scaled down and stored in the tcb.
This is a small (21K on sparc) editor that provides some powerful
features useful when a file needs editing on an embedded
board. No need to copy files off, edit, copy back.
Implement ctime and mtime updates according to POSIX. The ctime is
mapped to the FAT create time and date. The mtime is mapped to the FAT
last modified time and date. For the atime use the mtime for
simplicity.
