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

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.

Find the Linux driver for this controller,

it, and port the unavoidable parts of it to U-Boot.
Thanks. This would help for starting.

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.
