On Power machines supporting VRMA, Kexec/Kdump does not work. VRMA (virtual real-mode area) means that accesses with IR/DR = 0 (i.e. the MMU "off") actually still go through the hash table, using entries put there by the hypervisor. This means that when we clear out the hash table on kexec, we need to make sure these entries are left untouched. This also adds plpar_pte_read_raw() on the lines of plpar_pte_remove_raw().

In some of the PPC970 based systems, interrupt would be distributed to offline cpus also even when booted with "maxcpus=1". So check whether cpu online map and cpu present map are equal or not. If they are equal default_distrib_server is used as interrupt server otherwise boot cpu (default_server) used as interrupt server. In addition to this, if an interrupt is assigned to a specific cpu (ie smp affinity) and if that cpu is not online, the earlier code used to return the default_distrib_server as interrupt server. This introduces an additional parameter to the get_irq function, called strict_check. Based on this parameter, if the cpu is not online either default_distrib_server or -1 is returned.

There are 2 config options that indicate whether the platform being built has a device tree source file associated with it. Namely, CONFIG_WANT_DEVICE_TREE and CONFIG_DEVICE_TREE. When CONFIG_WANT_DEVICE_TREE is 'y' and CONFIG_DEVICE_TREE isn't an empty string, automatically wrap the specified device tree with the zImage being built. To achieve this, the 'dts' variable will only be set when the conditions above are true. The changes to the zImage.initrd.% and zImage.% rules cause the device tree to be wrapped when 'dts' is set; otherwise, they will work as they previosly did (i.e., build a zImage with no device tree).

cpu_purr_data is a per-cpu array used to account for stolen time on partitioned systems. It used to be the case that cpus accessed each others' cpu_purr_data, so each entry was protected by a spinlock. However, the code was reworked ("Simplify stolen time calculation") with the result that each cpu accesses its own cpu_purr_data and not those of other cpus. This means we can get rid of the spinlock as long as we're careful to disable interrupts when accessing cpu_purr_data in process context.

With both generic rtc and powerpc timer suspend / resume code now in the (powerpc.git) tree, powerpc platforms using the generic timer and enabling power management will have timer.o linked in the kernel, which they don't need. Moreover, it will likely WARN_ON(!ppc_md.get_rtc_time), save zero-time and return no error on suspend... As a possible solution we can choose not to build timer.o when RTC_CLASS is enabled. However, I can imagine systems with 2 rtc's, one served by the ppc-rtc, another one generic built as a module, in which case using the ppc-rtc for suspend / resume will be impossible. Not to say, that such a configuration would be ugly... Signed-off-by: NG. Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Glue code to hook up the pata_platform on the PA Semi Electra eval board. CFE sets up device tree entries for the IDE interface, with device type 'ide' and compatible field 'electra-ide'. We unfortunately need to modify the resources before calling the generic platform driver, since the device tree only has one register window in it and the driver expects two. Adding this as an of_platform driver instead doesn't give us any benefit, it just adds one more layer of register/probe functions. Since CONFIG_PATA_PLATFORM depends on CONFIG_EMBEDDED, add that as a default for PPC_PASEMI. Signed-off-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NPaul Mackerras <paulus@samba.org>

With this, when kexec-ing, we copy the code and start the slaves on their journey to the next kernel's spin loop as soon as we copy the kexec image into place. The kernel doesn't know exactly which slaves are spinning in kexec_wait. This allows us to pass more than max-cpus to the next kernel. But it also means that we might leave some behind. Moving the code here means they have the time it takes us to clear the hash table to wake up and move on. Moving the code any earlier would reuqire walking the image description to search for the code, which could span multiple pages.

This fixes some problems with the way the some things represented in the device tree for the Holly and Taiga boards. This means changes both to the dts files, and to the code which instantiates the tsi108 ethernet platform devices based on the device tree. - First, and most importantly, the ethernet PHYs are given with an identical 'reg' property. This reg currently encodes the accessible register used to initiate mdio interaction with the PHYs, rather than a meaningful address on the parent bus (mdio in this case), which is incorrect. Instead we give the address of these registers as 'reg' in the mdio node itself, and encode the ID of each phy in their 'reg' propertyies. - Currently the platform device constructor enables a workaround in the tsi108 ethernet driver based on the compatible property of the PHY. This is incorrect, because the workaround in question is necessary due to the board's wiring of the PHY, not the model of PHY itself. This patch alters the constructor to instead enable the workaround based on a new special property in the PHY node. - The compatible properties on a number of nodes in the device tree are insufficiently precise. In particular the PHYs give only "bcm54xx", which is broken, since there are many bcm54xx PHY models, and they have differences which matter. The mdio had a compatible property of "tsi-ethernet" identical to the ethernet MAC nodes, which doesn't make sense. The ethernet, i2c, bridge and PCI nodes were given only as "tsi-*" which is somewhat inprecise, we replace with "tsi108-*" in the case of Taiga (which has a TSI108 bridge), and "tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109 bridge). - We remove some "model" properties from the ethernets on Taiga board which were neither useful nor adequately precise. - On Holly we change to using a dtc label instead of a full path to reference the MPIC node, which makes the dts a little more readable.

Currently, the Holly device tree includes a bootargs property in /chosen, which gives a commandline. This is somewhat inconvenient, because it means an alternative default command line can't be given in the kernel config - the value obtained from the dts via the bootwrapper will always override CONFIG_CMDLINE. This removes the command line from the dts, and instead puts the same command line as a default in holly_defconfig.

The various cuboot platforms (i.e. pre-device tree aware u-boot for 83xx, 85xx and Ebony) share a certain amount of code for parsing the boot parameters. To a certain extent that's inevitable, since they platforms have different definitions of the bd_t structure. However, with some macro work and a helper function, this patch improves the situation a bit. In the process, this fixes a bug on Ebony, which was incorrectly handling the parameters passed form u-boot for the command line (the bug was copied from 83xx and 85xx which have subsequently been fixed).

In the device tree for Ebony, the 'ranges' property in the node for the EBC bridge shows the mappings from the chip select / address lines actually used for the EBC peripherals into the address space of the OPB. At present, these mappings are hardcoded in ebony.dts for the mappings set up by the OpenBIOS firmware when it configures the EBC bridge. This replaces the hardcoded mappings with code in the zImage to read the EBC configuration registers and create an appropriate ranges property based on them. This should make the zImage and kernel more robust to changes in firmware configuration. In particular, some of the Ebony's DIP switches can change the effective address of the Flash and other peripherals in OPB space. With this patch, the kernel will be able to cope with at least some of the possible variations.
