Subject: [PATCH] MIPS: Octeon: Fix DT pruning bug with pip ports
|
||||
|
||||
During the pruning of the device tree octeon_fdt_pip_iface() is called
|
||||
for each PIP interface and every port up to the port count is removed
|
||||
from the device tree. However, the count was set to the return value of
|
||||
cvmx_helper_interface_enumerate() which doesn't actually return the
|
||||
count but just returns zero on success. This effectively removed *all*
|
||||
ports from the tree.
|
||||
|
||||
Use cvmx_helper_ports_on_interface() instead to fix this. This
|
||||
successfully restores the 3 ports of my ERLite-3 and fixes the "kernel
|
||||
assigns random MAC addresses" issue.

Subject: [PATCH] MIPS: Octeon: Enable interfaces on EdgeRouter Lite
|
||||
|
||||
Enable interfaces on EdgeRouter Lite. Tested with cavium_octeon_defconfig
|
||||
and busybox shell. DHCP & ping works with eth0, eth1 and eth2.
|
||||
|
||||
The board type "UBNT_E100" is taken from the sources of the vendor kernel
|
||||
shipped with the product.

Subject: [PATCH] staging: MIPS: add Octeon USB HCD support
|
||||
|
||||
Add support for Octeon USB HCD. Tested on EdgeRouter Lite with USB
|
||||
mass storage.
|
||||
|
||||
The driver has been extracted from GPL sources of EdgeRouter Lite firmware
|
||||
(based on Linux 2.6.32.13). Some minor fixes and cleanups have been done
|
||||
to make it work with 3.10-rc3.
