FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64,
mips32r2 and mips64r2 (and close relatives) processors. There presently is support for ADMtek ADM5120, A mips 4Kc in a malta board, the RB533 routerboard (based on IDT RC32434) and some preliminary support for sibtye/broadcom designs. Other hardware support will be forthcomcing. This port boots multiuser under gxemul emulating the malta board and also bootstraps on the hardware whose support is forthcoming... Oleksandr Tymoshenko, Wojciech Koszek, Warner Losh, Olivier Houchard, Randall Stewert and others that have contributed to the mips2 and/or mips2-jnpr perforce branches. Juniper contirbuted a generic mips port late in the life cycle of the misp2 branch. Warner Losh merged the mips2 and Juniper code bases, and others list above have worked for the past several months to get to multiuser. In addition, the mips2 work owe a debt to the trail blazing efforts of the original mips branch in perforce done by Juli Mallett.

# 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.
