Problem w/ SATA/IDE on Kirkwood 88F6281 board:
I've got U-Boot 2011.12 working well on a 8192 Kirkwood board, _except_ for
a nagging SATA problem.
Currently, it loads and executes U-Boot fine, it boots fine from a USB
drive, but I'm unable to get the SATA port to function correctly. Any
insight from Albert, Prafulla or anyone else who recognizes this problem,
would be greatly appreciated.
It will detect an known-good-SATA-drive with known-good-ext2-partitions and
list its specs, but there are some errors:

To clarify, this is actually a _6192_ board. I double-checked, there are
no 6192 boards in include/configs/ .
The contents in arch/arm/arch-kirkwood/ certainly suggest that the 6192
is supported.

Hi David
6192 is supported for basic boot operation, no peripherals were tested on this platform.

I remember there was some delay issue on SATA, since processor in this platform is running at lower clock, (may be) this could be one of parameter to be considered.
May be Albert can have some more inside on this.

Hi Prafulla and hopefully Albert,
1 possibility ruled out, 1 tiny piece improved, 1 major problem still
there, & few questions...
0. Latest code in git shows the same behavior... that isn't the issue...
1. Adjusting some of the timings in drivers/block/mvsata_ide.c has allowed
me to apparently solve a _small_ fraction of the problem. I can now get it
to consistently/reliably honor the 'ide reset' command. (before this
timing adjustment, I would frequently see:
..................................
Pogov4> ide reset
Reset IDE: ide_preinit failed
``````````````````````````````````
... so this is one minor part of it that no longer seems a problem.
2. The two 'no IRQ' errors that I see here still persist:
..................................
Reset IDE: Bus 0: OK Bus 1: OK
Device 0: Model: TOSHIBA MK1655GSX Firm: FG010D Ser#: X9AHTNGQT
Type: Hard Disk
Supports 48-bit addressing
Capacity: 152627.8 MB = 149.0 GB (312581808 x 512)
Error (no IRQ) dev 0 blk 16: status 0x7f
No Powersaving mode 7F
Error (no IRQ) dev 0 blk 0: status 0x7f
Device 1: not available
``````````````````````````````````
These apparently come from common/cmd_ide.c . The offsets shown in the
DEBUG output look to me to be the correct ones, referencing the Marvell
docs.
I can't find a meaning for 'status 0x7f', though.
Again, any ideas or hints of what to examine would be appreciated.
3. Prafulla, could a problem w/ my kwbimage.cfg file cause timing
problems? Could the incorrect SoC identification (showing as a 6281
instead of a 6192) cause a problem due to some registers being misread
somehow?
Regards and thanks,
Dave

[Prafulla] : I don't think so, only TCLK is being configured to 166Mhz instead of 200, kwbimage.cfg does system configuration before boot, so whatever you do in this file are equally important.
But specific to this problem, I am bit away from peripheral sata :(
