* ARM: pm: convert some assembly to CRussell King2011-09-201-0/+8
| | | | | | | | | | | | | | | | Convert some of the sleep.S guts to C code, which makes it easier to use our macros and to add L2 cache handling. We provide a helper function, __cpu_suspend_save(), which deals with saving the common state, setting up for resume, and flushing caches. The remainder left as assembly code is the saving of the CPU general purpose registers, and allocating space on the stack to save the CPU specific registers and resume state.

* ARM: 6988/1: multi-cpu: remove arguments from CPU proc macrosWill Deacon2011-07-061-7/+7
| | | | | | | | | | | | | | The macros for invoking functions via the processor struct in the MULTI_CPU case define the arguments as part of the macros, making it impossible to take the address of those functions. This patch removes the arguments from the macro definitions so that we can take the address of these functions like we can for the !MULTI_CPU case.

* ARM: pm: add generic CPU suspend/resume supportRussell King2011-02-221-0/+7
| | | | | | | | | | | This adds core support for saving and restoring CPU coprocessor registers for suspend/resume support. This contains support for suspend with ARM920, ARM926, SA11x0, PXA25x, PXA27x, PXA3xx, V6 and V7 CPUs. Tested on Assabet and Tegra 2.

* ARM: move cache/processor/fault glue to separate include filesRussell King2011-02-121-235/+64
| | | | | | | | This allows the cache/processor/fault glue to be more easily used from assembler code. Tested on Assabet and Tegra 2. Tested-by: Colin Cross <ccross@android.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: Kill CONFIG_CPU_32Russell King2009-12-181-176/+198
| | | | | | | | 26-bit ARM support was removed a long time ago, and this symbol has been defined to be 'y' ever since. As it's never disabled anymore, we can kill it without any side effects. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* | [ARM] pxa: add base support for Marvell's PXA168 processor lineEric Miao2009-03-231-0/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | """The Marvell® PXA168 processor is the first in a family of application processors targeted at mass market opportunities in computing and consumer devices. It balances high computing and multimedia performance with low power consumption to support extended battery life, and includes a wealth of integrated peripherals to reduce overall BOM cost .... """ See http://www.marvell.com/featured/pxa168.jsp for more information. 1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core, there are many enhancements like instructions for flushing the whole D-cache, and so on 2. Clock reuses Russell's common clkdev, and added the basic support for UART1/2. 3. Devices are a bit different from the 'mach-pxa' way, the platform devices are now dynamically allocated only when necessary (i.e. when pxa_register_device() is called). Description for each device are stored in an array of 'struct pxa_device_desc'. Now that: a. this array of device description is marked with __initdata and can be freed up system is fully up b. which means board code has to add all needed devices early in his initializing function c. platform specific data can now be marked as __initdata since they are allocated and copied by platform_device_add_data() 4. only the basic UART1/2/3 are added, more devices will come later.
