[U-Boot] [PATCH v6 1/4] mx28: Let imx_get_mac_from_fuse be common for mx28

[Fabio Estevam]

Let imx_get_mac_from_fuse function be a common function, so that other
mx28 boards can reuse it.

Changes since v5:
- Allow the MAC vendor to be overriden
Changes since v4:
- No changes
Change since v3:
- Add a note about the first two MAC addresses being from Freescale vendor.

[U-Boot] [PATCH v6 2/4] mx28: Allow to set MAC address for the two FECs

[Fabio Estevam]

MX28 has two built-in FECs (Fast Ethernet Controller).

OCOTP register can be used to only store 4 bytes of MAC addresses.

In order to workaround this limitation, let the MAC address of FEC1 be
the FEC0 address plus one.

[U-Boot] [PATCH v6 4/4] mx28evk: Add initial support for MX28EVK board

[Fabio Estevam]

Add initial support for Freescale MX28EVK board.

Tested boot via SD card and by loading a kernel via TFTP through
the FEC interface.

Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

Changes since v5:
- Fix tab vs spaces on mx28evk.h
- Change return value on dram_init() 
Changes since v4:
- No changes
Changes since v3:
- Fix Copyright in mx28evk.h
- Call mx28_dram_init from dram_init
Changes since v2:

[U-Boot] [PATCH v6 1/4] mx28: Let imx_get_mac_from_fuse be common for mx28

[Marek Vasut]

> Let imx_get_mac_from_fuse function be a common function, so that other
> mx28 boards can reuse it.
> 
> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
> ---
> Changes since v5:
> - Allow the MAC vendor to be overriden
> Changes since v4:
> - No changes
> Change since v3:
> - Add a note about the first two MAC addresses being from Freescale vendor.

It's good, but why not make it completely generic -- like mx28_adjust_mac() -- 
so the users can for example change the last bit of the mac depending on the NIC 
that's used (FEC0 or FEC1). I think I proposed that. It's only a matter of 
adding a parameter (nic #) and renaming it :)

[U-Boot] [PATCH v6 2/4] mx28: Allow to set MAC address for the two FECs

[Marek Vasut]

> MX28 has two built-in FECs (Fast Ethernet Controller).
> 
> OCOTP register can be used to only store 4 bytes of MAC addresses.
> 
> In order to workaround this limitation, let the MAC address of FEC1 be
> the FEC0 address plus one.

No, please don't ... user might want to do this the other way around so just 
give him the freedom (and you're missing space before +) :) You can move exactly 
this code to the default implementation of mx28_mac_adjust().

> - For correct operation of saving environment variables into the SD card,
> the following patch is needed:
> http://lists.denx.de/pipermail/u-boot/2011-November/111448.html
> Changes since v5:
> - Fix tab vs spaces on mx28evk.h
> - Change return value on dram_init()
> Changes since v4:
> - No changes
> Changes since v3:
> - Fix Copyright in mx28evk.h
> - Call mx28_dram_init from dram_init
> Changes since v2:
> - Generate the patch again due to error in applying unrelated changes
> Changes since v1:
> - Read the MAC from fuses
> - Use tabs instead of space in u-boot.bd
> - Use puts instead of print
> - Factor out mac reading function
> - Factor out ddr size calculation function
> - Use GENERATED_GBL_DATA_SIZE

but imx_get_mac_from_fuse() is common to all IMX SOCs. Why do we need
another name only for MX28 ? I think it is better to adjust
imx_get_mac_from_fuse() to allow a second parameter (dev_id), that can
be ignored in other SOCs implementations.

Should be not better that the additional mac is computed by the (weak)
board function ? Then it is responsibility of the board and his
maintainer to change (if needed) the MAC for the second interface.

What is stored in MX28EVK CUST1 fuse? It seems to be CUST0 increased by 
one. So maybe we should read it from there for FEC1?

It would be nice to have very generic fuse reading function that could 
be used to read a serial number or similar user data. I will work this 
out if you don't like to do it. I'm quite busy now so it might take a 
week or two.

The release'll be early xmas present from Wolfgang, so you have those two weeks 
no problem ;-) Please go ahead and do it.

Does the mx28evk patch series look fine now?

Hi Fabio,

there are still open answers from me and Marek for the first patch:

 mx28: Let imx_get_mac_from_fuse be common for mx28

My main concern is that I dislike to have a new function name only for
the MX.28, and I would like to maintain the same set of functions for
all i.MX SOCs. The rest of the patchset is ok for me, I will send also
my Ack.

Best regards,
Stefano Babic

I thought that v8 took care of your concern:

Please let me know if you still would like me to rework this patch.

Sorry, I was not in CC and I missed it.
