Benjamin Herrenschmidt 28794d34ec powerpc/kconfig: Kill PPC_MULTIPLATFORM
CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
really meaningful anymore. It was basically equivalent to PPC64 || 6xx.

This removes it along with the following changes:

 - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
   on 6xx which is what they want anyway.

 - A new symbol, PPC_BOOK3S, is defined that represent compliance with
   the "Server" variant of the architecture. This is set when either 6xx
   or PPC64 is set and open the door for future BOOK3E 64-bit.

 - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
   PPC64 && PPC_BOOK3S

 - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
   used to control the use of prom_init.c

Josh Boyer 7fe519c207 powerpc: Introduce ppc_pci_flags accessors
Currently there are a number of platforms that open code access to
the ppc_pci_flags global variable.  However, that variable is not
present if CONFIG_PCI is not set, which can lead to a build break.

This introduces a number of accessor functions that are defined
to be empty in the case of CONFIG_PCI being disabled.  The
various platform files in the kernel are updated to use these.

In preparation of giving mii_bus objects a device tree presence of

having a 'struct device *dev' that points to our parent device

Kumar Gala 108443cb0c Revert "powerpc/ep8248e: Fix compile problem if !CONFIG_FS_ENET"
This reverts commit e3621ee633.

This was not the proper fix.  As Scott Wood said CONFIG_FS_ENET has nothing
to do with the issue.  The proper fix is to select PHYLIB for this board.

Kumar Gala ff21f23648 powerpc/ep8248e: Unconditionally select PHYLIB for mdio_bitbang
Its possible to build the phylib as a module, however this breaks the
board code because alloc_mdio_bitbang and mdiobus_register are not
available if we build as a module.  These are needed by the board code
since it implements the low level mdio bitbang ops.

So we unconditionally select PHYLIB to ensure its built into the kernel
if we are building in EP8248E support.

Long term we should look at moving the mdio_ops into its own file so it
can be built as a module.

pci_assign_all_busses global, that allow us to control various

This also adds the flag x86 already has to avoid ISA alignment
on bridges that don't have ISA forwarding enabled (no legacy
devices on the top level bus) and sets it for PowerMacs.

- corrected odd header name and fixed type in defines,
- Added 82xx subdir to the powerpc/platforms Makefile, missed during

- new solely-powerpc header file for 8260 family (was using one from
  arch/ppc, this one cleaned up from the extra stuff), in fact for now

Benjamin Herrenschmidt f90bb153b1 [POWERPC] Make pci_read_irq_line the default
This patch reworks the way IRQs are fixed up on PCI for arch powerpc.

It makes pci_read_irq_line() called by default in the PCI code for
devices that are probed, and add an optional per-device fixup in
ppc_md for platforms that really need to correct what they obtain
from pci_read_irq_line().

It also removes ppc_md.irq_bus_setup which was only used by pSeries
and should not be needed anymore.

I've also removed the pSeries s7a workaround as it can't work with
the current interrupt code anyway. I'm trying to get one of these
machines working so I can test a proper fix for that problem.

I also haven't updated the old-style fixup code from 85xx_cds.c
because it's actually buggy :) It assigns pci_dev->irq hard coded
numbers which is no good with the new IRQ mapping code. It should
at least use irq_create_mapping(NULL, hard_coded_number); and possibly
also set_irq_type() to set them as level low.
