What exactly do you mean by "libata"?   Do we have something like this
in U-Boot?

Incorrect multiline comment style.

Please do not add to this mess of tests, but introduce a single
feature-specific #define instead.

Ditto here and everywhere else.

This seems to be an unrelated change (like someother, smaller ones).
Please make sure to split your patches into independent parts.

Best regards,

My mistake: I meant ide. I'd started this work looking into the libata.c 
block driver but realized later that it wasn't what I needed, but the 
term stuck in my mind. I'll fix references to mention IDE instead.

Will this be ok?

	/*
	 * ED Mini V2 [...]
	 * disable [...]
	 */

	/* mask for [...] */

Will do. Would CONFIG_IDE_USE_INSW_OUTSW do? Basically, that's what the 
test is for: either use outsw()/insw() or use outw()/inw() within a loop.

Note that this change does not relate per se to my patch and requires 
addition of this #define to a lot of config header files. Wouldn't it be 
better if I submitted it as an independent atomic patch?

I'll put them in two separate patches, one for fixing typos and one for 
adding the CONFIG_SKIP_LOWLEVEL_INIT comments and line.

Or CONFIG_IDE_SWAP_IO or similar?

Indeed this should be then a part 1/N patch in your series.

Thanks.

They weren't that important. They were merely at the top. The  people
who  really  run organizations are usually found several levels down,
where it's still possible to get things done.

Note: commands "ide", "esxt2ls" and "ext2load" have been successfully 
tested. Command "diskboot" was not tested but should work as it requires 
no specific support wrt other disk-related commands.

Just a heads up. I posted a patch with a sata-driver for kirkwood a
while back. (We use this with our board and it seems to work fine)

http://lists.denx.de/pipermail/u-boot/2010-June/073147.html

Which might have some similarities to the sata controller on orion.

I was just trying to test it, May I know relevant board configs?

like egiga, we can think of having single sata driver for this.

On our board we have:

/*
 * Disk configuration
 */
#define CONFIG_SATA_MV
#define CONFIG_SYS_SATA_MAX_DEVICE      2

#ifdef CONFIG_SATA_MV
#define CONFIG_LBA48
#define CONFIG_LIBATA
#define CONFIG_CMD_SATA
#define CONFIG_DOS_PARTITION
#define CONFIG_CMD_EXT2
#endif


Hopefully i have not missed anything :)

I'm not against looking into integrating the sata-mv driver for orion5x 
as a SoC; but I'll retain the IDE approach at least for the ED Mini 
where NOR Flash space might be scarce and disk DMA at bootloader stage 
isn't a must IMO.

Regarding egiga sharing between kirkwood and orion5x, I have recently 
submitted a set of patches to the list with a request for comments.

Thanks Tor -- Now we're both informed of each other's dev. :)

First off : the MVSATAHX controller is indeed quite similar between both 
SoCs, at least from a u-boot perspective, where disk usage is limited to 
loading a kernel and initrd.

I see your sata_mv driver originates in the Linux kernel driver and 
makes use of DMA. This might be a real gain when loading big files often 
; in my case, I considered that u-boot will only kick in once in a while 
and load a less-than-2MB kernel and possibly a less-than-3MB initrd, and 
while relying on the IDE PIO code will certainly make it slower than 
with sata_mv, the occasional couple of 10th of ms is a fair price for 
the very small footprint -- ED Mini V2 is short on NOR Flash space.

Amicalement,

First off : the MVSATAHC controller is indeed quite similar between both 
SoCs, at least from a u-boot perspective, where disk usage is limited to 
loading a kernel and initrd. IIRC its code is already shared on the 
Linux side between orion5x and kirkwood.

I see your sata_mv driver originates in the Linux kernel driver and 
makes use of DMA. This might be a real gain when loading big files often 
; in my case, I considered that u-boot will only kick in once in a while
