powerpc/44x/Akebono: Remove select of IBM_EMAC_RGMII_WOL

2014-12-29T04:45:44+00:00

Commit 2a2c74b2efcb ("IBM Akebono: Add the Akebono platform") added a select of IBM_EMAC_RGMII_WOL. But that Kconfig symbol isn't (yet) part of the tree. So this select has been a nop since that commit was included in v3.16-rc1. Signed-off-by: Paul Bolle Acked-by: Alistair Popple Signed-off-by: Michael Ellerman

powerpc: Convert power off logic to pm_power_off

2014-11-03T01:12:51+00:00

The generic Linux framework to power off the machine is a function pointer called pm_power_off. The trick about this pointer is that device drivers can potentially implement it rather than board files. Today on powerpc we set pm_power_off to invoke our generic full machine power off logic which then calls ppc_md.power_off to invoke machine specific power off. However, when we want to add a power off GPIO via the "gpio-poweroff" driver, this card house falls apart. That driver only registers itself if pm_power_off is NULL to ensure it doesn't override board specific logic. However, since we always set pm_power_off to the generic power off logic (which will just not power off the machine if no ppc_md.power_off call is implemented), we can't implement power off via the generic GPIO power off driver. To fix this up, let's get rid of the ppc_md.power_off logic and just always use pm_power_off as was intended. Then individual drivers such as the GPIO power off driver can implement power off logic via that function pointer. With this patch set applied and a few patches on top of QEMU that implement a power off GPIO on the virt e500 machine, I can successfully turn off my virtual machine after halt.

IBM Akebono: Remove obsolete config select

2014-10-29T13:35:32+00:00

The original implementation of MMC support for Akebono introduced a new configuration symbol (MMC_SDHCI_OF_476GTR). This symbol has been dropped in favour of using the generic platform driver however the select for this symbol was mistakenly left in the platform configuration. This patch removes the obsolete symbol selection. Signed-off-by: Alistair Popple Signed-off-by: Paul Bolle Signed-off-by: Jiri Kosina

powerpc: make of_device_ids const

2014-09-25T13:14:46+00:00

of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by work with const of_device_ids. This allows to mark all struct of_device_id const, too. While touching these line also put the __init annotation at the right position where necessary.

lib/scatterlist: make ARCH_HAS_SG_CHAIN an actual Kconfig

2014-08-08T22:57:26+00:00

Rather than have architectures #define ARCH_HAS_SG_CHAIN in an architecture specific scatterlist.h, make it a proper Kconfig option and use that instead. At same time, remove the header files are are now mostly useless and just include asm-generic/scatterlist.h.

ppc476: Enable a linker work around for IBM errata #46

2014-04-30T22:26:34+00:00

This patch adds an option to enable a work around for an icache bug on 476 that can cause execution of stale instructions when falling through pages (IBM errata #46). It requires a recent version of binutils which supports the --ppc476-workaround option. The work around enables the appropriate linker options and ensures that all module output sections are aligned to 4K page boundaries. The work around is only required when building modules.
