Hi,

I am trying to compile new kernel to test GPIO pins, however, no
success for some time - kernel linking ends with error:

linking kernel.debug
ld: kernel.debug: warning: allocated section `.sdata' not in segment
ethernet-common.o: In function `cvm_assign_mac_address':
/usr/src/sys/mips/cavium/octe/ethernet-common.c:110: undefined
reference to
`cvmx_mgmt_port_num_ports' /usr/src/sys/mips/cavium/octe/ethernet-common.c:110:
relocation truncated to fit: R_MIPS_26 against
`cvmx_mgmt_port_num_ports' *** Error code 1

Searching in /sys/mips/cavium for cvmx_mgmt_port_num_ports is not
successfull - any insight here?
