79f49120ba powerpc/8xxx:Add MPH controller support in USB device-tree fixup
Add support for fixing usb mode and phy type for
MPH(Multi Port Host) USB controllers in device-tree nodes.
Required for socs like P3060, P5020, etc having MPH USB controller

5a52977f28 powerpc/8xxx: Cleanup USB device-tree fixup
Some code cleanup done for USB device-tree fixup:
	- handling error value returned from fdt_fixup_usb_mode_phy_type()
	- using ARRAY_SIZE macro
	- using snprintf instead of sprintf

4765fb7d73 powerpc/85xx: Fix warning for USB device-fixup
Fix USB device-fixup warning "node not found". This was occuring
because of static nature of start_offset variable

Static start_offset was storing offset of last node modified, and
was becoming issue if node fixup is carried multiple times,
resulting in "node not found" warning

9c42ef6145 powerpc/85xx: Update device tree handling for SRIO
Update device tree handling for SRIO controller to support updated
fsl,srio device tree binding.

We handle disabling of individual ports, the whole controller, RMU, and
RMAN.  Additionally, we setup the SRIO related LIODNs in the device
tree.

fbb9ecf749 powerpc/mp: add support for discontiguous cores
Some SOCs have discontiguously-numbered cores, and so we can't determine the
valid core numbers via the FRR register any more.  We define
CPU_TYPE_ENTRY_MASK to specify a discontiguous core mask, and helper functions
to process the mask and enumerate over the set of valid cores.

5756736176 powerpc/8xxx: Remove dependency on <usb.h>
We used <usb.h> for USB_MAX_DEVICE.  However this requires we actual
build in support for USB into u-boot (which should not be required for
device tree fixup).

At this time no FSL SoC that utilizies this code (83xx/85xx) has more
than 2 USB controllers.  So we replace USB_MAX_DEVICE with a local
define FSL_MAX_NUM_USB_CTRLS.

If/when a device shows up with more than 2 controllers we can easily
bump this value or refactor into a proper define per SoC.

a3a3e7b2c3 powerpc/85xx: enable USB2 gadget mode for corenet ds board
to make USB2 worked in gadget mode, we need to set it's 'dr_mode' to
'peripheral' in hwconfig, but driver starts scan from 'usb1', it'll break
out if it cannot find 'usb1', so drop the 'else' clause to make driver scan
all the 'usbx'.

72f4980b40 powerpc/8xxx: Update USB mode device tree fixup
Modify support for USB mode fixup:
        - Add common support for USB mode and phy type
          device tree fix-up for all USB controllers
          mentioned in hwconfig string
        - Fetch USB mode and phy type via hwconfig; if not
          defined in hwconfig, then fetch them from env

865ff85640 fsl: Change fsl_phy_enet_if to phy_interface_t
The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum.
This meant that drivers which used fsl_phy_enet_if to deal with
PHY interfaces would have to convert between the two (or we would have
to have them mirror each other, and deal with the ensuing maintenance
headache). Instead, we switch all clients of fsl_phy_enet_if over to
phy_interface_t, which should become the standard, anyway.

a09b9b68d4 powerpc/8xxx: Refactor SRIO initialization into common code
Moved the SRIO init out of corenet_ds and into common code for
8xxx/QorIQ processors that have SRIO.  We mimic what we do with PCIe
controllers for SRIO.

We utilize the fact that SRIO is over serdes to determine if its
configured or not and thus can setup the LAWs needed for it dynamically.

We additionally update the device tree (to remove the SRIO nodes) if the
board doesn't have SRIO enabled.

Introduced the following standard defines for board config.h:

CONFIG_SYS_SRIO - Chip has SRIO or not
CONFIG_SRIO1 - Board has SRIO 1 port available
CONFIG_SRIO2 - Board has SRIO 2 port available

(where 'n' is the port #)
CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot
CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup)
CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup)

[ These mimic what we have for PCI and PCIe controllers ]

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
