This is to keep ppc stuff still working mostly. Basically, whole this
header is for such aim.
To be specific, both fs_enet and cpm_uart will bail the compilation out
failing to find CPM_MAP_ADDR:

drivers/net/fs_enet/fs_enet-main.c:1144: error: 'CPM_MAP_ADDR'
undeclared (first use in this function)

and so forth.
