| * MIPS: Loongson 2F: Add CPU frequency scaling supportWu Zhangjin2009-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Loongson 2F supports CPU clock scaling. When put it into wait mode by setting the frequency as ZERO it will stay in this mode until an external interrupt wakes the CPU again. To enable clock scaling support, an external timer of a known stable rate is required.

| * MIPS: Add basic CPUFreq options.Wu Zhangjin2009-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds basic options for MIPS CPUFreq support. Since the cp0 timer's frequency is based on the processor clockrate it can not be used with CPUFReq; an additional external timer is required.

| * MIPS: Lemote 2F: Add cs5536 MFGPT timer supportWu Zhangjin2009-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CPUFreq support for Loongson 2F requires an external timer. Because the frequency of the MIPS Timer is related to the CPU frequency which itself is variable another timer of constant frequency is required. Export the mfgpt0 counter disable / enable operations for the coming suspend support to suspend / resume the timer.

| * MIPS: Loongson 2F: Add suspend support frameworkWu Zhangjin2009-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add basic suspend support for loongson2f family machines, loongson2f have a specific feature: when we set it's frequency to ZERO, it will go into a wait mode, and then can be waked up by the external interrupt. so, if we setup suitable interrupts before putting it into wait mode, we will be able wake it up whenever we want via sending the relative interrupts to it. These interrupts are board-specific, Yeeloong2F use the keyboard interrupt and SCI interrupt, but LingLoong and Fuloong2F use the interrupts connected to the processors directly. and BTW: some old LingLoong and FuLoong2F have no such interrupts connected, so, there is no way to wake them up from suspend mode. and therefore, please do not enable the kernel support for them. The board-specific support will be added in the coming patches.

The PCI-X controller has a programming interface similiar to the the FPGA northbridge used on Loongson 2E. The main differences between Loongson 2E and Loongson 2F include: 1. Loongson 2F has an extra address window configuration module, which is used to map CPU address space to DDR or PCI address space, or map the PCI-DMA address space to DDR or LIO address space. 2. Loongson 2F supports 8 levels of software configurable CPu frequency which can be configured in the LOONGSON_CHIPCFG0 register. The coming cpufreq and standby support are based on this feature. Loongson.h abstracts the modules and corresponding methods are abstracted. Add other Loongson-2F-specific source code including gcc 4.4 support, PCI memory space, PCI IO space, DMA address.

However, the PHYs for all the ports are controlled by a common MDIO bus. Because the mdio driver is not associated with a particular driver, but is instead a system level resource, we create s stand-alone driver for it. As for the driver, we put the register definitions in arch/mips/include/asm/octeon where most of the other Octeon register definitions live. This is a platform driver with the platform device for "mdio-octeon" being registered in the platform startup code. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Acked-by: David S.

This -v2 version incorporate the feedback from Ralf, and add the following changes: 1. add .ecoff, .bin, .erec format support 2. only enable it and the debug source code for the machines we tested 3. a dozen of fixups and cleanups and if you want to enable it for your board, please try to select SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then sending the relative patches to Ralf.

| | | | | | | | | | | | | | | | | | | | | | | | | | The simplest method was to add an extra asm-offsets.h file in arch/$ARCH/include/asm that references the generated file. We can now migrate the architectures one-by-one to reference the generated file direct - and when done we can delete the temporary arch/$ARCH/include/asm/asm-offsets.h file.
