To i.MX6SX/UL, two ethernet interfaces are supported.
Add ENET2 clock support:
1. Introduce a new input parameter "fec_id", only 0 and 1 are allowed.
To value 1, only i.MX6SX/UL can pass the check.
2. Modify board code who use this api to follow new api prototype.

Changes v2:
Addressed Fabio's comments. Using "fec_id == 0", but not "0 == fec_id".

The MIB RAM and FIFO receive start register does not exist on
i.MX6UL. Accessing these register will cause enet not work well.

Patch is already applied - however, I have found that this break build
for vf610 boards (they have not a get_cpu_rev()). You can check with the
current u-boot-imx.
Can you take a look, please ?

Sorry, I checked all i.MXes, but missed vf610.
>Can you take a look, please ?
I worked a simple patch: https://patchwork.ozlabs.org/patch/512669/
Add an empty function to avoid build errors. Current we do not have
drivers to check vf610 cpu types, later if we need saying
"is_cpu_type(VF610)", we can add more stuff to the function get_cpu_rev
for vf610.
Regards,
Peng.

No problem - we fix it !

I hoped to have a right get_cpu_rev() for VF610, too. Then I checked in
the VF610 manual, but I found revision only for specific controllers -
EHCI, etc. I have not found anything equivalent, but maybe it is better
hidden.
Of course, we can do with an empty function if we have not something
better. Maybe do you can check in Freescale if there is a way to get the
cpu revision instead of a dummy ?
Thanks,
Stefano Babic

2015-08-12 9:46 ` [U-Boot] [PATCH V2 3/3] imx: mx6ul_14x14_evk add ENET support Peng Fan
0 siblings, 1 reply; 15+ messages in thread
From: Peng Fan @ 2015-08-12 9:46 UTC (permalink / raw)
To: u-boot
To i.MX6SX/UL, two ethernet interfaces are supported.
Add ENET2 clock support:
1. Introduce a new input parameter "fec_id", only 0 and 1 are allowed.
To value 1, only i.MX6SX/UL can pass the check.
2. Modify board code who use this api to follow new api prototype.

Changes v2:
Addressed Fabio's comments. Using "fec_id == 0", but not "0 == fec_id".
