This patch causes a warning for the ea20 board:
davinci_emac.c: In function 'davinci_emac_initialize':
davinci_emac.c:901:2: warning: passing argument 1 of
'gen_auto_negotiate' makes integer from pointer without a cast
davinci_emac.c:355:12: note: expected 'int' but argument is of type 'u_int8_t *'

(found with ./MAKEALL -s davinci)

Regards, Christian
