# This board support package is not a board support package at all, but
|
||||
# a means to build the RTEMS kernel without using a specific BSP.
|
||||
#
|
||||
# You should be able to build to build this BSP for any cpu type.
|
||||
#
|
||||
# You must provide the standard BSP type functions and support yourself
|
||||
# externally to RTEMS.
|
||||
#
|
||||
# This BSP is intended to be used by people who fit one or more of the
|
||||
# categories below :
|
||||
#
|
||||
# 1) using custom hardware of little use or interest to others. If you
|
||||
# intend to use hardware available to others, please create a BSP
|
||||
# and send to OARCorp.
|
||||
#
|
||||
# 2) production code cannot depend on software which can change. BSP code
|
||||
# can change with-out notice, while RTEMS has very tightly defined
|
||||
# interfaces which do not change.
|
||||
#
|
||||
# 3) the need to extend or change an existing BSP in ways which are not
|
||||
# of interest to others or the BSP maintainer.
|
||||
#
|
||||
# I fit all the above.
