2014-04-07powerpc/p1010rdb: add P1010RDB-PB platform supportZhao Qiang
The P1010RDB-PB is similar to P1010RDB(P1010RDB-PA). So, P1010RDB-PB use the same platform file as P1010RDB. Then Add support for P1010RDB-PB platform.

2014-04-07powerpc/85xx: use one kernel option for all the CoreNet_Generic boardsKevin Hao
Currently all these boards use the same machine struct and also select the same kernel options, so it seems a bit of redundant to keep one separate kernel option for each board. Also update the defconfigs according to this change.

2014-04-07powerpc/85xx: rename the corenet_ds.c to corenet_generic.cKevin Hao
This file is also used by some RDB and QDS boards. So the name seems not so accurate. Rename it to corenet_generic.c. Also update the function names in this file according to the change.

2014-04-07powerpc/85xx: introduce corenet_generic machineKevin Hao
In the current kernel, the board files for p2041rdb, p3041ds, p4080ds, p5020ds, p5040ds, t4240qds and b4qds are almost the same except the machine name. So this introduces a cornet_generic machine to support all these boards to avoid the code duplication. With these changes the file corenet_ds.h becomes useless. Just delete it.

2014-04-05powerpc/pm: support deep sleep feature on T104xChenhui Zhao
T104x has deep sleep feature, which can switch off most parts of the SoC when it is in deep sleep mode. This way, it becomes more energy-efficient. The DDR controller will also be powered off in deep sleep. Therefore, the last stage (the latter part of fsl_dp_enter_low) will run without DDR access. This piece of code and related TLBs are prefetched in advance. Due to the different initialization code between 32-bit and 64-bit, they have seperate resume entry and precedure. The feature supports 32-bit and 64-bit kernel mode.

2014-01-06PPC: POWERNV: move iommu_add_device earlierAlexey Kardashevskiy
The current implementation of IOMMU on sPAPR does not use iommu_ops and therefore does not call IOMMU API's bus_set_iommu() which 1) sets iommu_ops for a bus 2) registers a bus notifier Instead, PCI devices are added to IOMMU groups from subsys_initcall_sync(tce_iommu_init) which does basically the same thing without using iommu_ops callbacks. However Freescale PAMU driver (https://lkml.org/lkml/2013/7/1/158) implements iommu_ops and when tce_iommu_init is called, every PCI device is already added to some group so there is a conflict. This patch does 2 things: 1. removes the loop in which PCI devices were added to groups and adds explicit iommu_add_device() calls to add devices as soon as they get the iommu_table pointer assigned to them. 2. moves a bus notifier to powernv code in order to avoid conflict with the notifier from Freescale driver. iommu_add_device() and iommu_del_device() are public now.

2013-11-20powerpc: Make cpu_to_chip_id() available when SMP=nMichael Ellerman
Up until now we have only used cpu_to_chip_id() in the topology code, which is only used on SMP builds. However my recent commit a4da0d5 "Implement arch_get_random_long/int() for powernv" added a usage when SMP=n, breaking the build. Move cpu_to_chip_id() into prom.c so it is available for SMP=n builds. We would move the extern to prom.h, but that breaks the include in topology.h. Instead we leave it in smp.h, but move it out of the CONFIG_SMP #ifdef. We also need to include asm/smp.h in rng.c, because the linux version skips asm/smp.h on UP. What a mess.

I have more fixes but not related to LE so I'll send them as a separate pull request tomorrow, let's get this one out of the way. Note that this supports running user space binaries using the new ABI, but the kernel itself still needs to be built with the old one. We'll bring fixes for that after -rc1. Here's Anton log that goes with this series: This patch series adds support for the new ABI, LPAR support for H_SET_MODE and finally adds a kconfig option and defconfig. ABIv2 support was recently committed to binutils and gcc, and should be merged into glibc soon. There are a number of very nice improvements including the removal of function descriptors.

We're assigning PE numbers after the completion of PCI probe. During the PCI probe, we had PE#0 as the super container to encompass all PCI devices. However, that's inappropriate since PELTM has ascending order of priority on search on P7IOC. So we need PE#127 takes the role that PE#0 has previously. For PHB3, we still have PE#0 as the reserved PE. The patch supposes that the underly firmware has built the RID to PE# mapping after resetting IODA tables: all PELTM entries except last one has invalid mapping on P7IOC, but all RTEs have binding to PE#0.
