Hi all,
Looking at the custodians list on the Denx site, I haven't found one for ide or mass storage. Did I miss him/her? If not, then, apart from Prafulla's for Marvell stuff, whose Ack or Nak should I expect for this patch set?
Thanks in advance,
Amicalement, Albert.

This configuration option replaces a complex conditional in cmd_ide.c with an explicit define to be added to SoC or board configs.
Signed-off-by: Albert Aribaudalbert.aribaud@free.fr
This patch set introduces CONFIG_IDE_SWAP_IO as suggested by Wolfgang Denk, adds orion5x support to cmd_ide.c and adds IDE support to edminiv2.
Patchset history:
V1: Initial 4-patch set -- not cleanly submitted (does not appear on gmane for instance) and contained some unrelated changes.
V2: Slimmed down to 3 patches and removed unrelated changes.
V3: Back to 4 patches (cmd_ide improvement, driver addition, cmd_ide support for orion, edminiv2 support for sata); made initialization code reuseable as a block driver ; moved to C structures; commented some constants.
V4: Reordered objects alphabetically in drivers/block/Makefile. Shortened mv_sata to mvsata. Removed volatile qualifier in mvsata port structure. Moved port pointer definition from SoC to board code. Removed unrelated changes.
V5: Fixed typo in mvsata_ide driver (IMP, should have been IPM).
