Re: [U-Boot] net, cpsw: disable gigabit support through plattform data

Dear Heiko,

In message 1370335914-14027-1-git-send-email-hs@denx.de you wrote:

add possibility to disable gigabit support through plattform data. Current boards should not be affected through this patch.

...

• if (phy->speed == 1000) {
  

• 	if (priv->data.gigabit_en) {
  

• 		mac_control |= GIGABITEN;
  

• 	} else {
  

• 		/* Disable gigabit as it's non-functional */
  

• 		mac_control &= ~GIGABITEN;
  

• 		phy->speed = 100;
  

Is this reliable? I mean, how do we know it's a 100 Mbps connection (and not for example a 10 Mbs one) ?

Best regards,

Wolfgang Denk
