2013-11-06powerpc/powernv: Add PE to its own PELTVGavin Shan
We need add PE to its own PELTV. Otherwise, the errors originated from the PE might contribute to other PEs. In the result, we can't clear up the error successfully even we're checking and clearing errors during access to PCI config space.

2013-11-06powerpc/powernv: Add support for indirect XSCOM via debugfsBenjamin Herrenschmidt
Indirect XSCOM addresses normally have the top bit set (of the 64-bit address). This doesn't work via the normal debugfs interface, so we use a different encoding, which we need to convert before calling OPAL. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-11-06powerpc/scom: Improve debugfs interfaceBenjamin Herrenschmidt
The current debugfs interface to scom is essentially unused and racy. It uses two different files "address" and "data" to perform accesses which is at best impractical for anything but manual use by a developer. This replaces it with an "access" file which represent the entire scom address space which can be lseek/read/writen too. This file only supports accesses that are 8 bytes aligned and multiple of 8 bytes in size. The offset is logically the SCOM address multiplied by 8. Since nothing in userspace exploits that file at the moment, the ABI change is a no-brainer. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-11-06powerpc/scom: Enable 64-bit addressesBenjamin Herrenschmidt

2013-11-05powerpc/boot: Properly handle the base "of" boot wrapperBenjamin Herrenschmidt
The wrapper script needs an explicit rule for the "of" boot wrapper (generic wrapper, similar to pseries). Before 0c9fa29149d3726e14262aeb0c8461a948cc9d56 it was hanlded implicitly by the statement: platformo=$object/"$platform".o But now that epapr.o needs to be added, that doesn't work and an explicit rule must be added.

2013-10-30powerpc/pseries: Fix dedicated processor partition detectionAnton Blanchard
commit f13c13a00512 (powerpc: Stop using non-architected shared_proc field in lppaca) fixed a potential issue with shared/dedicated partition detection. The old method of detection relied on an unarchitected field (shared_proc), and this patch switched to using something architected (a non zero yield_count). Unfortunately the assertion in the Linux header that yield_count is only non zero on shared processor partitions is not true. It turns out dedicated processor partitions can increment yield_count and as such we falsely detect dedicated partitions as shared. Fix the comment, and switch back to using the old method.

Commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the wrapper to fit the kernel") adjusts the wrapper address unnecessarily for platforms that use arch/powerpc/boot/of.c, since the code there allocates space for the kernel wherever it can find it and doesn't necessarily load the kernel at address 0. Changing the link address is actually harmful since it can cause the zImage to overlap with Open Firmware and thus fail to boot.
