[U-Boot-Users] Silicon Image 0680A and CF-ATA drive

[Sam Pham]

Hi all,

My custom board has the PCI to ATA chip Silicon Image
0680A, which connects to the CompactFlash Storage Card
that acts as a standard IDE disk if configured right. 
Anyone knows if U-boot already had the implementation
for the Silicon Image 0680A and CF-ATA drive?  I
looked through the source code but didn't find
anything.  If not, any recommendations of how to
implement them?

Any pointer is appreciated.

Sam

Find the Linux driver for this controller, analyze it, and  port  the
unavoidable parts of it to U-Boot.

Thanks.  This would help for starting.

[U-Boot-Users] Silicon Image 0680A and CF-ATA drive

[Rune Torgersen]

I use a 0680A under u-boot, using the standard IDE driver. Works
perfect. Only had to give the IDE driver the address of the register
base.
#define CFG_ATA_BASE_ADDR			0xa0000000 //
BaseAddress 5
#define CFG_ATA_REG_OFFSET			0x80
#define CFG_ATA_DATA_OFFSET			0x80
#define CFG_ATA_ALT_OFFSET			0x80

It's good to know that somebody had implemented uboot
for the Sil 0680A controller.  Do you have a patch for
this driver?  I'd like compare it with my
implementation to see if I'm missing anything because
I  can't test my implementation until the eval board
arrives.  Also, did you implement POST for this
controller?  I plan to do this as well.

Thanks.

[U-Boot-Users] Silicon Image 0680A and CF-ATA drive

[Rune Torgersen]

Didn't implement anything at all. I just used the generic IDE driver
already present in U-Boot.
All I had to change were those four #defines.

If you turned on PCI_CONFIG_PNP this might break, especially if the
ide adapter was on a card and/or there were other cards as options.

For a generic driver it might be better to use pci_find_device() to
fetch the register addressing.

[Rune Torgersen]

Which is excactly what I am doing on real HW. The base address define is
set to a variable that I use pci_find_device() and base address register
5 to set the address of.

I also use pci_find_device() to get the bdf value of
the Sil 0680A device on the PCI bus, then use this bdf
to allocate memory for BARs.  And according to the
datasheet, I/O space access, memory space access, and
bus master operation need to be enabled as well.  So
some implementation are needed besides changing the
config params.  Moreover, since I'd like to support
POST for this device and the CF-ATA drives that
connect to it, my driver needs to do more than these
basic steps.
