      powerpc: Add skeleton PowerNV platform · 55190f88
      由 Benjamin Herrenschmidt 提交于 
      This adds a skeletton for the new Power "Non Virtualized"
platform which will be used by machines supporting running
without an hypervisor, for example in order to run KVM.

These machines will be using a new firmware called OPAL
for which the support will be provided by later patches.

The PowerNV platform is intended to be also usable under
the BML environment used internally for early CPU bringup
which is why the code also supports using RTAS instead of
OPAL in various places.

      powerpc: introduce the ePAPR embedded hypervisor vmpic driver · 3a93261f
      由 Ashish Kalra 提交于 
      The Freescale ePAPR reference hypervisor provides interrupt controller
services via a hypercall interface, instead of emulating the MPIC
controller.  This is called the VMPIC.

The ePAPR "virtual interrupt controller" provides interrupt controller
services for external interrupts.  External interrupts received by a
partition can come from two sources:

  - Hardware interrupts - hardware interrupts come from external
    interrupt lines or on-chip I/O devices.
  - Virtual interrupts - virtual interrupts are generated by the hypervisor
    as part of some hypervisor service or hypervisor-created virtual device.

Both types of interrupts are processed using the same programming model and
same set of hypercalls.

      powerpc/5xxx: extend mpc8xxx_gpio driver to support mpc512x gpios · e39d5ef6
      由 Anatolij Gustschin 提交于 
      The GPIO controller of MPC512x is slightly different from
8xxx GPIO controllers. The register interface is the same
except the external interrupt control register. The MPC512x
GPIO controller differentiates between four interrupt event
types and therefore provides two interrupt control registers,
GPICR1 and GPICR2. GPIO[0:15] interrupt event types are
configured in GPICR1 register, GPIO[16:31] - in GPICR2 register.

This patch adds MPC512x speciffic set_type() callback and
updates config file and comments. Additionally the gpio chip
registration function is changed to use for_each_matching_node()
preventing multiple registration if a node claimes compatibility
with another gpio controller type.

      powerpc/chrp: Use the same RTAS daemon as pSeries · 3d541c4b
      由 Benjamin Herrenschmidt 提交于 
      The CHRP code has some fishy timer based code to scan the RTAS event
log, which uses a 1KB stack buffer and doesn't even use the results.

The pSeries code as a nicer daemon that allows userspace to read the
event log and basically uses the same RTAS interface

This patch moves rtasd.c out of platform/pseries and makes it usable
by CHRP, after removing the old crufty event log mechanism in there.

The nvram logging part of the daemon is still only available on 64-bit
since the underlying nvram management routines aren't currently shared.

      powerpc/kconfig: Kill PPC_MULTIPLATFORM · 28794d34
      由 Benjamin Herrenschmidt 提交于 
      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

      powerpc/amigaone: Add platform support for AmigaOne · 54b318aa
      由 Gerhard Pircher 提交于 
      This commit adds the setup code for booting Linux on AmigaOne G3SE (G3
only), AmigaOne XE and uA1 (G3/G4) desktop computers. These boards were
sold by Eyetech and are based on MAI Logic's Teron boards and its
Articia S northbridge.
The AmigaOne uses U-boot as firmware, which doesn't support a flattened
device tree yet. The northbridge has some design flaws, which makes it
necessary to use non cacheable memory for DMA operations
(CONFIG_NOT_COHERENT_CACHE) and to avoid setting the coherence (M) flag
for memory pages.
