2015-10-27Merge branch 'clock' into HEADScott Wood
This is a major overhaul of the clk-qoriq driver, which I'm merging via PPC with Stephen Boyd's ack in order to apply subsequent PPC patches that depend on it.

2015-10-17powerpc/85xx: Don't use generic timebase sync on 64-bitScott Wood
85xx currently uses the generic timebase sync mechanism when CONFIG_KEXEC is enabled, because 32-bit 85xx kexec support does a hard reset of each core. 64-bit 85xx kexec does not do this, so we neither need nor want this (nor is the generic timebase sync code built on ppc64). FWIW, I don't like the fact that the hard reset is done on 32-bit kexec, and I especially don't like the timebase sync being triggered only on the presence of CONFIG_KEXEC rather than actually booting in that environment, but that's beyond the scope of this patch...

2015-10-17powerpc/fsl-corenet: Disable coreint if kexec is enabledScott Wood
Problems have been observed in coreint (EPR) mode if interrupts are left pending (due to the lack of device quiescence with kdump) after having tried to deliver to a CPU but unable to deliver due to MSR[EE] -- interrupts no longer get reliably delivered in the new kernel. I tried various ways of fixing it up inside the crash kernel itself, and none worked (including resetting the entire mpic). Masking all interrupts and issuing EOIs in the crashing kernel did help a lot of the time, but the behavior was not consistent. Thus, stick to standard IACK mode when kdump is a possibility.

2015-10-17powerpc/fsl-booke-64: Allow booting from the secondary threadScott Wood
This allows SMP kernels to work as kdump crash kernels. While crash kernels don't really need to be SMP, this prevents things from breaking if a user does it anyway (which is not something you want to only find out once the main kernel has crashed in the field, especially if whether it works or not depends on which cpu crashed).

The environment is, instead, stored on an MMC card on the motherboard.

2015-06-02powerpc: mpc85xx: flush the l1 cache before cpu down in kexecKevin Hao
We observe a "Zero PT_NOTE entries found" warning when vmcore_init() is running on the dump-capture kernel. Actually the PT_NOTE segments is not empty, but the entries generated by crash_save_cpu() are not flushed to the memory before we reset these cores. So we should flush the l1 cache as what we do in cpu hotplug. With this change, we can also kill the mpc85xx_smp_flush_dcache_kexec() since that becomes unnecessary. Please note: this only fix the issue on e500 core, we still need to implement the function to flush the l2 cache for the e500mc core. Fortunately we already had proposing patch for this support [1]. Hope we can fix this issue for e500mc after that merged.

2014-11-03powerpc: Convert power off logic to pm_power_offAlexander Graf
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.

2014-09-03powerpc/fsl-pci: Limit ZONE_DMA32 to 2GiB on 64-bit platformsScott Wood
FSL PCI cannot directly address the whole lower 4 GiB due to conflicts with PCICSRBAR and outbound windows. By the time max_direct_dma_addr is set to the precise limit, it will be too late to alter the zone limits, but we should always have at least 2 GiB mapped (unless RAM is smaller than that).

2014-07-29powerpc/e6500: Add support for hardware threadsAndy Fleming
The general idea is that each core will release all of its threads into the secondary thread startup code, which will eventually wait in the secondary core holding area, for the appropriate bit in the PACA to be set. The kick_cpu function pointer will set that bit in the PACA, and thus "release" the core/thread to boot. We also need to do a few things that U-Boot normally does for CPUs (like enable branch prediction).

This patch introduces the support for Keymile's kmcoge4 board which is the internal reference design for boards based on Freescale's P2040/P2041 SoCs. This internal reference design is named kmp204x. The peripherals used on this board are: - SPI NOR Flash as bootloader medium - NAND Flash with a ubi partition - 2 PCIe busses (hosts 1 and 3) - 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5) - 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt CPLD - 2 I2C busses - last but not least, the mandatory serial port The patch also adds a defconfig file for this reference design that is necessary because of the lowmem option that must be set higher due to the number of PCIe devices with big ioremapped mem ranges on the boad.

2014-03-19fsl/pci: The new pci suspend/resume implementationWang Dongsheng
If we do nothing in suspend/resume, some platform PCIe ip-block can't guarantee the link back to L0 state from sleep, then, when we read the EP device will hang. Only we send pme turnoff message in pci controller suspend, and send pme exit message in resume, the link state will be normal. When we send pme turnoff message in pci controller suspend, the links will into l2/l3 ready, then, host cannot communicate with ep device, but pci-driver will call back EP device to save them state. So we need to change platform_driver->suspend/resume to syscore->suspend/resume. So the new suspend/resume implementation, send pme turnoff message in suspend, and send pme exit message in resume. And add a PME handler, to response PME & message interrupt. Change platform_driver->suspend/resume to syscore->suspend/resume. pci-driver will call back EP device, to save EP state in pci_pm_suspend_noirq, so we need to keep the link, until pci_pm_suspend_noirq finish.
