New Revision: 299994
URL: https://svnweb.freebsd.org/changeset/base/299994
Log:
[mips/broadcom] Add initial support for Broadcom MIPS processor
Relies on BHND(4) driver.
There files contains machine-dependent code for Broadcom MIPS processor and
provide UART driver.
This is a work in progress; it and the current bhnd code is enough to boot
on the ASUS RT-N16 and RT-N53 platforms.
