[U-Boot] [PATCH V3 00/13] Support for HTKW mcx board

[U-Boot] [PATCH V3 00/13] Support for HTKW mcx board

[Ilya Yanok]

Hi All,

these patches introduce support for HTKW mcx board (AM3517-based)
including DaVinci EMAC driver fixes to work on AM35xx, SPL fixes
and OMAP3 EHCI support.

This is an updated version of previously posted patches:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/116535

Patches are rebased on the current master and no-op implementation
for dcache operations on arm926ejs added.

[U-Boot] [PATCH 01/13] davinci_emac: move arch-independent defines to separate header

[Ilya Yanok]

DaVinci EMAC is found not only on DaVinci SoCs but on some OMAP3 SoCs
also. This patch moves common defines from arch-davinci/emac_defs.h to
drivers/net/davinci_emac.h

DaVinci specific PHY drivers hacked to include the new header. We might
want to switch to phylib in future.

I missed the 0/13 email but, patches 1 to 10 will be queued up into
u-boot-ti, Scott mentioned a problem with 11, I haven't seen anything
about 12 (but it's delegated to someone else) and I've commented on
13.  This should at least reduce the repost burden, thanks for all
your patience here!

Good to hear, you are a co-custodian for u-boot-ti, I really like it, but...
You should let patches hang a little on the list...
This version was published just 1.5 days ago...
You should let people look into this, otherwise, you can find
yourself reapplying new versions or applying fixes to what could have
been fixed...

True, but the changes you object to were around for a while longer
than that.  And really what needs to happen with this driver is
switching to phylib (like the kernel version does).

That is also true, I admit.
Meanwhile, shouldn't we make at least this one kind of clearer?
Because, future intend is not an excuse for ugly code, right?

Relative includes are also relatively common.  This wins on depth,
true.  Albert?  Wolfgang?  Is this "too ugly to live" and we need to
fix it or live with it until we can switch to phylib?

Doesn't this look terrible?
I'd suggest, to split the davinci_emac.h to driver private part
(if there is) and to public part.
Then put the public part into the include/ directory - just as,
for example, dm9000 does.

Other then that, the patch indeed good and very useful.
Thanks.

Yes, it does. But this will be removed once someone will switch the
driver to phylib.

Uh.. As for me, polluting the public includes is not very good idea as
well. And again I think switching to phylib use is the right solution.
This should be rather simple.

Hmmm... and who will be that someone?
Is it on someone's TODO list?

Why is that? If you need the functionality used outside of the
drivers/net directory, then I think it is the way.
To reduce the garbage in include/ it can be split into subdirs,
so for example all network related .h files will reside in include/net/

> And again I think switching to phylib use is the right solution.
> This should be rather simple.

Agreed, but if you still see this ugly thing in a year or so,
it will mean that you just merged ugly code with hope that it will
be fixed some day and it has been a year already, right?

Instead, my proposed solution will not prevent switching
to phylib, but will still look better even if that someone
(who supposed to do the switch) will not switch the driver to phylib.
Unless, you want it to look ugly, so that someone will hurry up...

If it is so painful for you to use my proposed solution or
you think it is worth than the current one, you can merge this.
I don't really want to block it.

[U-Boot] [PATCH 02/13] davinci_emac: use internal addresses in buffer descriptors

[Ilya Yanok]

On AM35xx CPPI RAM had different addresses when accessed from the CPU
and from the EMAC. We need to account this to deal with the buffer
descriptors correctly.

[U-Boot] [PATCH 04/13] arm926ejs: add noop implementation for dcache ops

[Ilya Yanok]

Added noop implementation for dcache operations that will buzz
about missing real implementation and disable the dcache.
This fixes compilation of DaVinci EMAC driver on arm926ejs.

[U-Boot] [PATCH 05/13] davinci_emac: fix for running with dcache enabled

[Ilya Yanok]

DaVinci EMAC is present on TI AM35xx SoCs (ARMv7) which run with D-Cache
enabled by default. So we have to take care and flush/invalidate the
cache before/after the DMA operations.

Please note that the receive buffer alignment to 32 byte boundary comes
from the old driver version I don't know if it is really needed or
alignment to cache line size is enough.

[U-Boot] [PATCH 09/13] nand_spl_simple: add support for software ECC

[Ilya Yanok]

This patch adds support for software ECC to the nand_spl_simple driver.
To enable this one have to define CONFIG_SPL_NAND_SOFTECC.

Tested on OMAP3.

[U-Boot] [PATCH 11/13] nand_spl_simple: store temp data at CONFIG_SPL_NAND_WORKSPACE

[Ilya Yanok]

Currently nand_spl_simple puts it's temp data at 0x10000 offset in SDRAM
which is likely to contain already loaded data. I can't see any way to
determine some safe address automagically so make it up to board porter
to provide the safe-to-use address via CONFIG_SPL_NAND_WORKSPACE value.

If you change this, you probably should change also
the second version of this function (CONFIG_SYS_NAND_HW_ECC_OOBFIRST)
or instead pass it as a parameter to the finction(s) from an upper layer.

Have you tried to use the stack as a buffer for those calculations?

Maybe it is better to not have a default value somewhere in the SDRAM
and to get a compile error. If we do not want to fix also the related
boards, we could at least use a #warn message to advise at compile time
that a default value is taken (and at the end, to force the board
maintainers to fix it...).

Stefano Babic

My intention was not to break something as I can't fix every board using
this driver. That's why I preserved the existing address for the case
where CONFIG_SPL_NAND_WORKSPACE is not defined.

Probably. Wolfgang, Scott, do you think we should add a warning here?

How many boards are using the new SPL for NAND so far?  It shouldn't be
that bad to just fix them.

How much space are we talking about?  Can it be put on the stack?

Well, currently the code uses 0x200 + CONFIG_SYS_NAND_OOBSIZE bytes but
I think a lot of this space is unused. What we really need is
CONFIG_SYS_NAND_ECCTOTAL + CONFIG_SYS_NAND_OOBSIZE. This is probably
acceptable to put on the stack.

Regards, Ilya.

I think we are talking about 24 bytes, getting the value for
CONFIG_SYS_NAND_ECCTOTAL in the configuration file.

Reading the code it is not clear to me why the computed ecc is stored in
this way at a fixed offset in RAM - anybody knows why cannot we set a
static char ecc_calc[] at the beginning of the nand_spl_simple.c file ?

OMAP_HSMMC requires GENERIC_MMC so just defined(CONFIG_OMAP_HSMMC) &&
!definedCONFIG_SPL_BUILD) like the rest is all that's needed.

Should be removed, isn't used.

This is unused with SPL.

Are you sure you don't just need 16 here?  This is arguments to u-boot
commands and not related to being able to pass in lots of stuff to the
kernel via command line.  (And yes, I know where you got this from,
putting those to 16 is on my low hanging fruit list).

And from that same source you copy/pasted a few incorrect multiline
comments (the /* ------... ones).

And given we don't define CONFIG_USE_IRQ..

Better as (45 << 10).

I swear I saw Wolfgang say (45 << 10) for another board (and we do N
<< 10 in other places in the config files) but either way.

Matter of taste... For KiB it makes not much difference, but for MiB a
"45 << 20" is way easier to write and read than a "45 * 1024 * 1024".

return omap_mmc_init(0);

I would also define this function ("weak") in some common place,
so we will not need to copy/paste it all over the boards, but
of course, it is not a blocker and I don't request this from you.
Only if you want to... :-)

probably, you should check here for failure and

Well, we can use cpu_mmc_init() for this. But what slot(s) should we
initialized in this common function? First? All?

The problem we have here is that board_mmc_init and cpu_mmc_init are
already both weak and you can't replace one weak function with another
weak function (or if you can, you need to play linker games).  I had
given this a quick stab but not reported back since I hadn't finished
the rest of the related task (SPL and MMC support for am335x).

I don't really understand the issue. We don't even have to play with the
weak functions, generic MMC code already does this. We can just provide
the cpu_mmc_init function for OMAPs (which we don't have at the moment).
The only problem I can see is how to tell this cpu_mmc_init function
which slots to initialize. Probably we could use some configuration
defines for this.

Ah, I hadn't been thinking of it that way.  Perhaps a
omap-common/mmc.c that tries and init's them all will do, but needs a
lot of testing first.  And a little bit of thinking to make sure the
one interface case isn't ugly too (am33xx).

Please, add version history, next time, so it can be easily
understood, what has been fixed and what hasn't been fixed.
It makes a review of the new version much easier.

Also, if you use '--cover-letter' with git format-patch, you also get
a nice diff stat, which can help identify, what files are involved.

Ok.

Actually I've addressed all comments during previous round. The only
difference from V2 is added no-op cache functions for arm926ejs.

Good!
IMO, having *all* versions history in each new version is more
useful then just the incremental updates, but either way is better
than nothing ;-) .
