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

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.

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.

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?

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.

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.

Hey, that's great to hear! :)

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.

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.

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...).

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.

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.

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..
+#define CONFIG_SPL_MAX_SIZE 0xB400 /* 45 K */
Better as (45 << 10).

Maybe 45 * 1024?
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.

Dear Andy Fleming,
In message CAKWjMd7_sXJxfJX=vVyYSXW8nv33PZfUCFSTeLCu7Qu-KnPSjQ@mail.gmail.com you wrote:
+#define CONFIG_SPL_MAX_SIZE =A0 =A0 =A0 =A0 =A0 =A00xB400 =A0/* 45 K */
Better as (45 << 10).
Maybe 45 * 1024?
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".
Best regards,
Wolfgang Denk

Hi Igor,
thanks for your comments.

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).

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.
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.
understood, what has been fixed and what hasn't been fixed. It makes a review of the new version much easier.
Actually I've addressed all comments during previous round. The only difference from V2 is added no-op cache functions for arm926ejs.

Will do.
Thanks.

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 ;-) .
