[PATCH 0/8] IBM Akebono/PPC476GTR Support

[PATCH 0/8] IBM Akebono/PPC476GTR Support

[Alistair Popple]

The IBM Akebono board is a development board for the new PPC476GTR
system on chip (SoC).

Changes from V1:
 * Update device-tree compatible strings to reflect the name of the
   SoC rather than the board when those components are integrated into
   the SoC.
 * Updates to allow the new EMAC PHY interface to be compile tested.
 * Rather than adding a new compatible string for EHCI support
   usb-ehci is used and the corresponding driver (ehci-ppc-of)
   is merged into the generic EHCI platform driver.
 * A generic (usb-ohci) compatible string is used for OHCI.
 * PCI MSI support has been added via the HSTA module.

Alistair Popple (8):
  IBM Akebono: Add support to AHCI platform driver
  IBM Akebono: Add a SDHCI platform driver
  IBM Akebono: Add support for a new PHY interface to the IBM emac
    driver
  IBM Akebono: Add support to the OHCI platform driver for PPC476GTR
  ECHI Platform: Merge ppc-of EHCI driver into the ehci-platform driver
  IBM Currituck: Clean up board specific code before adding Akebono
    code
  IBM Akebono: Add the Akebono platform
  powerpc: Added PCI MSI support using the HSTA module

Re: [PATCH 2/8] IBM Akebono: Add a SDHCI platform driver

[Alistair Popple]

Hi,

I originally sent this to the linuxppc-dev list thinking Ben H might take it, 
however it should go through the appropriate subsystem. Can someone please 
merge it into the appropriate tree (unless the are problems with it)?

Thanks.

Regards,

Alistair
