4# The Broadcom Sentry5 series of processors and boards is very commonly
5# used in COTS hardware including the Netgear WGT634U.
6#
7# Some tweaks are needed for use with this platform:
8#
9# * CFE firmware's ELF loader expects an ELF kernel which is linked so as
10#   not to contain offsets in PT_LOAD which point behind the actual offset
11#   of that PT header. FreeBSD normally links the first PT_LOAD header to
12#   begin at offset 0.
13#
14# * Broadcom's support package for the internal bus, the Sonics
15#   SiliconBackplane, needs to be integrated to detect and probe hardware
16#   correctly.
17#
18# * The clock needs to be calibrated correctly, so that DELAY() may work.
19#   One problem with this is that the low-level printf() routine calls DELAY(),
20#   which currently causes divide-by-zero trap
21#
22# * The Broadcom CPUs have no FPU. Attempting to detect one by reading CP1's
23#   status register causes an unhandled boot-time exception. An FPU emulator
24#   will be necessary to support multi-user boot.
