Several boards are using the built-in SPI controller of the AR71XX/AR724X/AR913X SoCs. This patch adds common platform_device and helper code to register it. Additionally, the patch registers the SPI bus on the PB44 board. Signed-off-by:

The Atheros AR71XX/AR724X/AR913X SoCs have a built-in SPI controller. This patch implements a driver for that. Signed-off-by:

Almost all boards have one or more push buttons connected to GPIO lines. This patch adds common code to register a platform_device for them. The patch also adds support for the buttons on the PB44 board. Signed-off-by:

This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches. Signed-off-by:

In order not to be left behind, we add jump label support for MIPS. Tested on 64-bit big endian (Octeon), and 32-bit little endian (malta/qemu). Signed-off-by:

On the off chance that uasm ever warns about overflow, there is no way to know what the offending instruction is. Change the printks to WARNs, so we can get a nice stack trace. It has the added benefit of being much more noticeable than the short single line warning message, so is less likely to be ignored. Signed-off-by:

If the CPU supports BBIT0 and BBIT1, use them in TLB handlers as they are more efficient than an AND followed by an branch and then restoring the clobbered register. Signed-off-by:

This patch adds a generic solution to support multiple machines based on a given SoC within a single kernel image. It is implemented already for several other architectures but MIPS has no generic support for that yet. [Ralf: This competes with DT but DT is a much more complex solution and this code has been used by OpenWRT for a long time so for now DT is a bad reason to stop the merge but longer term this should be migrated to DT.] Signed-off-by:

When DEBUG_LL is not set, we don't want __error_a re-entering __lookup_machine_type - we want it to go to the error function. This used to be the case before we reorganized the layout for hotplug cpu, as we used to fall through to __error. With the changed layout, we need an explicit branch here instead.

Drive strength for PXA910 is a 2 bit value but because of the mapping in plat-pxa/mfp.h needs to be shifted up one bit to handle real location in mfp registers. (MMP2 and PXA910 drive strength start at bit 11 while PXA168 starts at bit 10). Values 0, 1, 2, and 3 effectively need to be 0, 2, 4, and 6 to fit into register. 8 does not work. Signed-off-by:

Rabin Vincent reports: | On SMP, this BUG() in save_stack_trace_tsk() can be easily triggered | from user space by reading /proc/$PID/stack, where $PID is any pid but | the current process: | | if (tsk != current) { | #ifdef CONFIG_SMP | /* | * What guarantees do we have here that 'tsk' | * is not running on another CPU? | */ | BUG(); | #else Fix this by replacing the BUG() with an entry to terminate the stack trace, returning an empty trace - I'd rather not expose the dwarf unwinder to a volatile stack of a running thread.
