[U-Boot] Marvell Armada XP SATA support

[Anton Schubert]

Hello,

we are trying to replace an old marvell uboot on mv78260 with the current
version, but noticed that there doesn't seem to be a driver for the SATA
controller.
Are there any plans to support SATA on Armada XP or is our only option to
migrate the old driver?

Regards
Anton

Is the Marvell SATA controller AHCI compatible? If yes, U-Boot has the
AHCI driver which should work.

Great. Welcome. :)

No, the AXP SATA controller is unfortunately not AHCI compatible (the 
A38x seems to be though). The mvsata driver (drivers/block/mvsata_ide.c) 
might be a pretty good start for the AXP though (I didn't check this 
closely).

Thanks,
Stefan

Hi,
many thanks for your hints.

I managed to get ide_ident working with mvsata_ide.c by setting the Sata
address windows (using mbus.c analogous to the mvneta driver). But I'm kind
of stuck now as ATA reads will just result in timeouts:

ide_read dev 0 start 0, blocks 1 buffer at 7FBA9C60
ide_outb (dev= 0, port= 0x118, val= 0xe0) : @ 0xf10a2118
ide_inb (dev= 0, port= 0x11c) : @ 0xf10a211c -> 0x50
ide_outb (dev= 0, port= 0x11c, val= 0xe5) : @ 0xf10a211c
ide_inb (dev= 0, port= 0x11c) : @ 0xf10a211c -> 0x50
ide_inb (dev= 0, port= 0x108) : @ 0xf10a2108 -> 0xff

ide_inb (dev= 0, port= 0x11c) : @ 0xf10a211c -> 0xd0
ide_inb (dev= 0, port= 0x11c) : @ 0xf10a211c -> 0x51
Error (no IRQ) dev 0 blk 0: status 0x51


This is my current ide config:
#define __io
#define CONFIG_IDE_PREINIT
#define CONFIG_MVSATA_IDE

/* Needs byte-swapping for ATA data register */
#define CONFIG_IDE_SWAP_IO

#define CONFIG_SYS_ATA_REG_OFFSET        0x0100      /* Offset for normal

#define CONFIG_SYS_ATA_DATA_OFFSET    0x0100      /* Offset for data I/O */
#define CONFIG_SYS_ATA_ALT_OFFSET        0x0100      /* Offset for data I/O
*/

/* Each 8-bit ATA register is aligned to a 4-bytes address */
#define CONFIG_SYS_ATA_STRIDE        4

/* CONFIG_CMD_IDE requires some #defines for ATA registers */
#define CONFIG_SYS_IDE_MAXBUS          2
#define CONFIG_SYS_IDE_MAXDEVICE       2

/* ATA registers base is at SATA controller base */
#define CONFIG_SYS_ATA_BASE_ADDR    MVEBU_SATA_BASE /* 0xA0000 */
#define CONFIG_SYS_ATA_IDE0_OFFSET    0x2000

#define CONFIG_DOS_PARTITION

I would be grateful for any pointers.

Anton

Just send me the missing code (mbus address window setup etc) and I'll 
give it a try on my DB-MV784MP-GP board.

Thanks,

That should be it. Although it's probably a good idea to do this in cpu.c
as you did with your a38x ahci support.
Thanks for your help.

Hi,

I figured out my problem was just ATA security. After unlocking the code
above works fine for MV78260.

Thanks,
 Anton

Great. Then please send a patch to the list to add support for SATA on AXP.

Should i move the mbus init code to mach-mvebu/cpu.c for that purpose?
Additionally, what would you recommend for the MVEBU_SATA_BASE define as it
would be ambiguous after the a38x patch.

Thanks,
Anton

No, please keep it in the driver. I only moved it into cpu.c since there 
is no MVEBU specific driver in the AHCI/SATA case.

Why not just use the same name/macro?

I think it would be a bit confusing with MVEBU_SATA0_BASE for A38X and
MVEBU_SATA_BASE for AXP in the same header. (As I don't have access to the
A38X Spec I don't know how similar they really are)

Do the addresses differ? If not, then please use the same macro and 
perhaps add a comment, that on AXP this is not AHCI compatible. And on 
A38x it is.

If the addresses differ, I suggest to use a name like:

MVEBU_AXP_SATA_BASE

Thanks,
Stefan
