* Blackfin: gpio: use shorter nameMichael Hennerich2010-03-091-1/+1
| | | | | | | | | The gpio label size is 16 char, but the current code uses a longer name resulting in chopped display. So use a shorter name.

* Blackfin: fix MPU page permission masks overflow when dealing with async memoryBarry Song2010-03-093-11/+38
| | | | | | | | | | | | | Attempting to use the MPU while doing XIP out of parallel flash hooked up to the async memory bus would often result in random crashes as the MPU slowly corrupted memory. The fallout here is that the async banks gain MPU protection from user space too. So any accesses have to go through the mmap() interface rather than just using hardcoded pointers.

* Blackfin: flush caches on SMP when one core calls another via IPIYi Li2010-03-091-2/+24
| | | | | | | | | Sometimes a SMP system will randomly panic at boot. This is due to caches being out of sync when one core tries to signal the other.

| * platform-drivers: move probe to .devinit.text in arch/armUwe Kleine-König2010-03-074-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A pointer to a probe callback is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. Similar to sysdev_attributes and normal attributes. This is a tree-wide sweep, converting everything in one go. No functional changes in this patch other than passing the new argument everywhere. Tested on x86, the non x86 parts are uncompiled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NUMAQ initialization sets x86_init.pci.init to pci_numaq_init, which obviously isn't defined if CONFIG_PCI isn't defined. This dependency was implicit in the past, because pci_numaq_init was invoked from arch/x86/pci/legacy.c, which itself was conditioned on CONFIG_PCI. I suspect that no NUMA-Q machines without PCI were ever built, so instead of complicating the code by adding #ifdefs or stub functions, just disable this bit of the configuration space.

| * | x86, apbt: Moorestown APB system timer driverJacob Pan2010-02-244-0/+862
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Moorestown platform does not have PIT or HPET platform timers. Instead it has a bank of eight APB timers. The number of available timers to the os is exposed via SFI mtmr tables. All APB timer interrupts are routed via ioapic rtes and delivered as MSI. Currently, we use timer 0 and 1 for per cpu clockevent devices, timer 2 for clocksource.

| * | x86/PCI: Moorestown PCI supportJesse Barnes2010-02-232-1/+259
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Moorestown platform only has a few devices that actually support PCI config cycles. The rest of the devices use an in-RAM MCFG space for the purposes of device enumeration and initialization. There are a few uglies in the fake support, like BAR sizes that aren't a power of two, sizing detection, and writes to the real devices, but other than that it's pretty straightforward. Another way to think of this is not really as PCI at all, but just a table in RAM describing which devices are present, their capabilities and their offsets in MMIO space. This could have been done with a special new firmware table on this platform, but given that we do have some real PCI devices too, simply describing things in an MCFG type space was pretty simple.
