This config option is used to make sure that changes does not impact non-T1040 platforms. -replaces mfspr(x) macro defintion to check if above erratum is defined and if x is same as SPRN_PVR, then return static value else call mfspr instruction. -Similarly replaces mfpvr() calls TODO: 1.Use some cleaner approach like reading SVR rgeister or parse device tree to check if T1040 Rev1.0 Si instead of using config option. 2.This patch only replaces current accesses of PVR register but does not restrict any new code which tries to read this.

2014-05-14Kind of revert "powerpc: 52xx: provide a default in mpc52xx_irqhost_map()"Wolfram Sang
This more or less reverts commit 6391f697d4892a6f233501beea553e13f7745a23. Instead of adding an unneeded 'default', mark the variable to prevent the false positive 'uninitialized var'. The other change (fixing the printout) needs revert, too. We want to know WHICH critical irq failed, not which level it had.

2014-05-14powerpc/pm: add API for setting powerdown exceptionZhao Chenhui
Add fsl_set_power_except() for setting powerdown exception when sleep. The drivers can call this function to set the corresponding bits if the devices will power down when sleep. This patch also fixed an issue which is that FMan ports can not work after wake-up from deep sleep using Wake-on-LAN. Set FMan bit and MAC bits of the register IPPDEXPCR seperately, instead of setting them together.

2014-04-29fsl/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.
