# $FreeBSD$
#
# The Broadcom Sentry5 series of processors and boards is very commonly
# used in COTS hardware including the Netgear WGT634U.
#
# Some tweaks are needed for use with this platform:
#
# * CFE firmware's ELF loader expects an ELF kernel which is linked so as
# not to contain offsets in PT_LOAD which point behind the actual offset
# of that PT header. FreeBSD normally links the first PT_LOAD header to
# begin at offset 0.
#
# * Broadcom's support package for the internal bus, the Sonics
# SiliconBackplane, needs to be integrated to detect and probe hardware
# correctly.
#
# * The clock needs to be calibrated correctly, so that DELAY() may work.
# One problem with this is that the low-level printf() routine calls DELAY(),
# which currently causes divide-by-zero trap
#
# * The Broadcom CPUs have no FPU. Attempting to detect one by reading CP1's
# status register causes an unhandled boot-time exception. An FPU emulator
# will be necessary to support multi-user boot.
