On the READ_LATENCY, you probably want | PHY_EN_DYN_PWRDN for that
(since it's not part of MT41J128MJT125_EMIF_READ_LATENCY) bit of
savings.

Why are we bringing this in?

And are you unable to run at 400MHz here?  Or just weren't aware /
having tried updating the timing parameters, etc?

Is this all that was needed for both interfaces to work in U-Boot, along
with a config change or two?  If so, I should take a stab at getting
both working on the EVM-SK.

Can't you just do that in the struct?  And avoid the checkpatch warning
too.

But you have NOR.  Is it not working yet?

Please see doc/README.memory-test and then eiter update the range to be
most of memory or drop these and add #undef CONFIG_CMD_MEMTEST.

I see this is a copy/paste problem too from am335x_evm.h, can you fix
there and pcm051.h?

Same (not needed anymore, not sure how it didn't get removed before).

Do you really have the EEPROM at 0x50 like the TI boards do (and then at
other offets for capes/daughter cards) ?

Another problem duplicated from am335x_evm.h :(

This isn't quite right.  Your first 128k chunks are ROM-checked
redundant locations for SPL to live (hence the write of U-Boot at 512k
in).

> +#undef CONFIG_ENV_IS_NOWHERE

Did you ever set this?  I don't think so... on am335x_evm.h we do since
we can build for SPI env or NAND env.

All that said, yay for another board to try and help flush out generic
problems in am33xx land!

Okay, I'd not looked at the DDR setup in great detail, simply copying 
what the EVM-SK did.

There's currently no way to enable BCH8 ECC mode.  I need this so that 
all writes to the on-board NAND have the correct ECC values.

There's a similar bunch of code in the OMAP3 board.c file, so I just 
copied that principal.

Ah ... I've just seen this changed recently (don't know why my code even 
compiles now as the headers are different !!).  I'll just back this out 
and use the existing version.

Again, I just copied the EVM-SK code.

DDR3 is a new technology for us, but now the board essentially works I 
should (when I have time !!) be able do some further timing tweaks.

Yes ... the config change is just to set CONFIG_PHY_ADDR to the correct 
value.

Unfortunately, since the CONFIG_PHY_ADDR value is "hard-coded" into 
quite a bit of the uboot code, to change ports, you need to re-compile 
!!  Not ideal, and I don't suppose it's too much work to get both
working together, but I don't see much demand for it.

Sure, will do.

We do have NOR and it's working, but it doesn't contain any "user 
accessible" data.  We use it as long-term storage using a custom layout, 
so there's no point in exposing it to uboot.

I'll just drop memtest.

Sure, I'll post a "remove duplicate #defines" patch.

Ok.

Yes, but it doesn't contain the same TI EEPROM data structure.  In fact, 
at the moment, it doesn't contain anything (!!).

It's just there for future expansion .... in which case, should I remove 
the #defines for the time being ?

I'll add it to the "remove duplicates" patch.

Ah, I see ... so that's part of on-chip "bios" ... nice!!

I'll put them back in.

Okay.

Well, this board certainly knock the socks off it's predecessor (based 
on the AVR32).  We're getting a 10-14x performance boost :-)

Thanks for the review ... I'll post a v2 shortly.

Right, for am335x we just always do BCH8 in hardware (can't easily make
SW matching BCH8).  Once we have BCH16 it'll also be automatic switching
since that's what the ROM does and we always want to be ROM-compatible.

You should be able to come up with optimal ones with your DDR data sheet
and the TRM at hand.

Ah, so it's not quite right :(  Other platforms support multiple
interfaces, but I don't know how they're setup.

A comment above please, roughly to that effect?

No, that's fine, just making sure it's really there.

Replied a bit too soon on this one ... I thought they were duplicated, 
but they're not.

what's the problem with these lines ?

'#define<tab>' not '#define<space>'.  A general fixup patch is fine.

Actually, neither CONFIG_SYS_NAND_ECCTOTAL nor CONFIG_SYS_NAND_ECCSTEPS 
are used anywhere in the code !!

I'll just remove them.

A small nit-pick, you sent the commit using email id as "mpfj-list@mimc.co.uk"
But in the maintainer file, it shows as "mpfj@newflow.co.uk".

Is this valid/correct?

Yes ... the newflow address is my official work one.

But I have a separate email address for all my mailing lists which makes 
sorting out my mailboxes *so* much easier.

I trust this isn't an issue.

AFAIK Email id in Maintainer file will be used for all communications. 

So I believe, you have enabled mail fwd from mpfj@newflow.co.uk to mpfj-list@mimc.co.uk

I don't mind "direct" contact on my standard email address ... I just
have all my mailing list traffic sent to another email address.

I've actually now change to mpfj-list at newflow.co.uk, so does that
make things a bit clearer ?

Forgive my ignorance, but where does the 400MHz come from ?

I thought that 303MHz was the max clock speed on the AM335x (TRM
7.3.2.2), or am I missing something ?

Ah, OK.  The nearly released now board I'm referring to that does have
400MHz there has newer silicon that does really support DDR3-800 and
there is a new TRM that reflects this.  I suspect however you have
PG1.0 and 303 is your max speed.  Sorry for the confusion!

Tom

I can see in drivers/net/cpsw.c:-

static int cpsw_phy_init(struct eth_device *dev, struct cpsw_slave *slave)
{
...
	phydev = phy_connect(priv->bus,
			CONFIG_PHY_ADDR,
			dev,
			slave->data->phy_if);
...
}

As you can see the hardcoded CONFIG_PHY_ADDR is being used, despite the
fact that it might be different for each slave.

Could you just replace that with "slave->data->phy_id" ?

I'll give it a try and see what happens.

Cheers
Mark J.

No, that doesn't fix things.

It looks like the PHY device is stored in the cpsw struct (rather than
in the slave struct) ... from cpsw.c:-

struct cpsw_priv {
	struct eth_device		*dev;
	struct cpsw_platform_data	data;
	int				host_port;

	struct cpsw_regs		*regs;
	void				*dma_regs;
	struct cpsw_host_regs		*host_port_regs;
	void				*ale_regs;

	struct cpdma_desc		*descs;
	struct cpdma_desc		*desc_free;
	struct cpdma_chan		rx_chan, tx_chan;

	struct cpsw_slave		*slaves;
	struct phy_device		*phydev; <<<<<<<<<<<<<<<<<
	struct mii_dev			*bus;

	u32				mdio_link;
	u32				phy_mask;
};

So there's an assumption that you can only have a single PHY (even
though you can have 2 slaves).

I've gone as far as I dare with my limited knowledge.

Mark J.
