As specified by e0229a16b0 if the VR9
based router provides FXS ports and they should enabled then the
following must added to the kernel command line:
mem=[TOTALMEMSIZE-2M] vpe1_load_addr=ADDRESS vpe1_mem=2M
By adding mem= parameter a pci device stop working correctly. The
pci-lantiq.c module use get_num_physpages() to compute dynamically the
memory amount of the board.
The mem= make the module to compute in the wrong way the BAR11MASK, so
in this situation the mask is misaligned with the dma area that the
hardware expects.
This patch is a port of what legacy ifxmips_pci.c does.
