this is not -- we want it to return 0 if no parts are found.  see recent net 
doc updates and discussions.

these changes in general look good, but if you're going to modify the common 
header, you need to update the eeprom code as well to set up the name field

It seems that eeprom code is broken since commit
736fead8fdbf8a8407048bebc373cd551d01ec98: "Convert SMC911X Ethernet
driver to CONFIG_NET_MULTI API".
I'll try to come up with a fix, but I have no way to test it.

broken how ?  i recall it working ...

> I'll try to come up with a fix, but I have no way to test it.

any board that has a smc911x part can test this code easily.  it doesnt 
require an eeprom to be hooked up to the smc911x part.  you can still dump on-
chip registers as well as poke the eeprorm interface.

It gives pretty long list of compile errors. The smc911x.h header has
now 'struct eth_device *dev' parameter in all the functions.

yeah, i see that now.  it wasnt noticed earlier as the config name changed but 
the eeprom code wasnt updated.  i can take a look if you like since i wrote 
this sucker in the first place.

You fixed the SMC91111 eeprom code by defining a 'struct eth_dev', but I 
guess not the SMC9111x.  I'm responsible for making this mess, so if you 
don't have time I can take care of it (without being able to test, of 
course :)

We can probably still fit such a bug fix in this release if we act quickly.

Ben

Cute

This looks good to me.

Mike R - is there a chance that you can test this out?
If not, I'd argue that even untested it has a fighting chance of working 
and as such is better than what's already in the code base, and should 
be picked up ASAP.

Ben

[U-Boot] [PATCH] smc911x_eeprom: fix building after smc911x overhaul

[Mike Frysinger]

When the smc911x driver was converted to NET_MULTI, the smc911x eeprom was
missed.  The config option needed updating as well as overhauling of the
rergister read/write functions.

[U-Boot] [PATCH v2] smc911x_eeprom: fix building after smc911x overhaul

[Mike Frysinger]

When the smc911x driver was converted to NET_MULTI, the smc911x eeprom was
missed.  The config option needed updating as well as overhauling of the
rergister read/write functions.

I've tested your changes, MAC register dumps works Ok. I needed to
make some changes to make it work, see the comments below.

Needed to add 'void *priv' needed for smc911x_detect_chip, otherwise
it does not compile with the latest U-Boot.

Should be if (smc911x_detect_chip(dev)) since smc911x_detect_chip
returns 0 on success.

This requires memset on arches that use C version (e.g. ARM). For my
testing I've just copied the memset from lib_generic/string.c, but
obviously it's not the correct solution.

i wrote it against last release which didnt need this.  looking at smc911x.h, 
obviously priv is needed now and shouldnt be a problem adding it.

[U-Boot] [PATCH 3/5] smc911x: silence MAC mismatch warning

[Mike Rapoport]

If there is no SROM attached to the SMSC chip it's MAC address is
initialized to ff:ff:ff:ff:ff:ff and it causes the following
warning:

    Warning: smc911x-0 MAC addresses don't match:
    Address in SROM is         ff:ff:ff:ff:ff:ff
    Address in environment is  00:01:ba:dc:0d:03

Set dev->enetaddr only if MAC address is valid, and thus avoid the
above case.

someone already posted a patch for this issue:
	NET: Fix MAC addr handling for smc911x

i think the approach they took is better -- they check for explicit values 
that indicate 'no srom is attached' rather than 'is the mac valid' as your 
code could ignore attached srom's but bad addresses.  in this latter case, i 
think we want the warning.

[U-Boot] [PATCH 5/5] smc911x: allow mac address to be kept after smc911x_halt

[Mike Rapoport]

The smc911x_halt gets called after completion of network opration
and resets the chip. When there is no SROM attached to the SMSC, MAC
address gets reset as well. Add CONFIG_SMC911X_KEEP_MAC option to allow
boards with no SROM instruct the SMSC driver to keep mac address after the
reset

the mac already has proper storage -- the environment.  please read 
doc/REAdME.enetaddr.  so i dont thinkt his option should be added.

If you have no network activity in U-Boot the mac address never gets from the
environment to the SMSC chip. So, when the kernel boots there's no mac address
neither in the chip registers nor in (absent) SROM.

this is correct u-boot behavior.  please read the faq.
