CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Setting G5's cpu frequency transition latency to CPUFREQ_ETERNAL stops ondemand governor from working. I measured the latency using sched_clock and haven't seen much higher than 11000ns, so I set this to 12000ns for my configuration. Possibly other configurations will be different? Ideally the generic code would be able to measure it in case the platform does not provide it. But this simple patch at least makes it throttle again.

There are hardware limitations on the number of available MSIs, which firmware expresses using a property named "ibm,pe-total-#msi". This property tells us how many MSIs are available for devices below the point in the PCI tree where we find the property. For old firmwares which don't have the property, we assume there are 8 MSIs available per "partitionable endpoint" (PE). The PE can be found using existing EEH code, which uses the methods described in PAPR. For our purposes we want the parent of the node that's identified using this method. When a driver requests n MSIs for a device, we first establish where the "ibm,pe-total-#msi" property above that device is, or we find the PE if the property is not found. In both cases we call this node the "pe_dn". We then count all non-bridge devices below the pe_dn, to establish how many devices in total may need MSIs. The quota is then simply the total available divided by the number of devices, if the request is less than or equal to the quota, the request is fine and we're done. If the request is greater than the quota, we try to determine if there are any "spare" MSIs which we can give to this device. Spare MSIs are found by looking for other devices which can never use their full quota, because their "req#msi(-x)" property is less than the quota. If we find any spare, we divide the spares by the number of devices that could request more than their quota. This ensures the spare MSIs are spread evenly amongst all over-quota requestors.

If a driver asks for more MSIs than the devices "req#msi(-x)" property, we currently return -ENOSPC. This doesn't give the driver any chance to make a new request with a number that might work. So if "req#msi(-x)" is less than the request, return its value. To be 100% safe, make sure we return an error if req_msi == 0.

This commit adds the setup code for booting Linux on AmigaOne G3SE (G3 only), AmigaOne XE and uA1 (G3/G4) desktop computers. These boards were sold by Eyetech and are based on MAI Logic's Teron boards and its Articia S northbridge. The AmigaOne uses U-boot as firmware, which doesn't support a flattened device tree yet. The northbridge has some design flaws, which makes it necessary to use non cacheable memory for DMA operations (CONFIG_NOT_COHERENT_CACHE) and to avoid setting the coherence (M) flag for memory pages.

The EEH code disables and enables interrupts during the device recovery process. This is unnecessary for MSI and MSI-X interrupts because they are effectively disabled by the DMA Stopped state when an EEH error occurs. The current code is also incorrect for MSI-X interrupts. It doesn't take into account that MSI-X interrupts are tracked in a different way than LSI/MSI interrupts. This patch ensures only LSI interrupts are disabled/enabled.

This patch adds IRQ controller support to the MPC5200 General Purpose Timer (GPT) device driver. With this patch the mpc5200-gpt driver supports both GPIO and IRQ functions. The GPT driver was contained within the mpc52xx_gpio.c file, but this patch moves it out into a new file (mpc52xx_gpt.c) since it has more than just GPIO functionality now and it was only grouped with the mpc52xx-gpio drivers as a matter of convenience before. Also, this driver will most likely get extended again to also provide support for the timer function. Implementation note: Alternately, I could have tried to implement the IRQ support as a separate driver and left the GPIO portion alone. However, multiple functions of this device (ie. GPIO input+interrupt controller, or timer+GPIO) can be active at the same time and the registers are shared so it is safer to contain all functionality within a single driver.

Rework the mpc5200-pic driver to simplify it and fix up the setting of desc->status when set_type is called for internal IRQs (so they are reported as level, not edge). The simplification is due to splitting off the handling of external IRQs into a separate block so they don't need to be handled as exceptions in the normal CRIT, MAIN and PERP paths.
