I'm also using the Marvel 88E1111 PHY with no problems. Note that you must follow the reset waveform exactly per the data sheet or the PHYs will be in la la land. Hopefully the reset discrete is connect to a GPIO pin. Since this PHY can not be strapped for RGMII, you also must set register 20 to 0xce3 in your board specific initialization followed by a soft reset.

Hello,
as mentioned before i´m using two Marvel 88E1111
PHY on my PPC440GX Board.
They are configured as a RGMII to copper interface
for use with EMAC 2 & 3.
So now i´m in trouble with the configuration of
the network. After booting i
set with "setenv ethact ppc_440x_eth2" EMAC2 for
networking. After that i
try a "ping" to know if network is working.
Reading the speed and duplex
from PHY works, but after that i got in an endless
loop. I figured out, that
no interrupt is recognized and in 440gx_enet.c in
ppc_440x_eth_init the
default configuration of the interrupt handler is
for ETH0:
irq_install_handler (VECNUM_EWU0 + (hw_p->devnum
- 2),
(interrupt_handler_t *) enetInt, dev); irq_install_handler (VECNUM_ETH0 + (hw_p->devnum
- 2),
(interrupt_handler_t *) enetInt, dev);so i changed it as following...
irq_install_handler (VECNUM_EWU2 + (hw_p->devnum
- 2),
(interrupt_handler_t *) enetInt, dev); irq_install_handler (VECNUM_ETH2 + (hw_p->devnum
- 2),
(interrupt_handler_t *) enetInt, dev);You shouldn't need to do this. I have 3 different boards that work fine with emac2 & emac3.
and added in vecnum.h these lines:
#define VECNUM_ETH2 (64 + 0) /* Ethernet
0 interrupt status */
#define VECNUM_EWU2 (64 + 1) /* Ethernet
0 wakeup */
But this didn´t solve the problem. Actually i also
couldn´t get the TxCLK
work on my RGMII Bridge and i don´t know why.
I saw the note yesterday about the etch length. The hw guys didn't want to route the 13" of extra etch so I whack a reg in our phy to tell it to skew the clock.
