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.
