*	avr32: Add MMIO address definitions for certain controllers	Haavard Skinnemoen	2008-08-08	1	-3/+1
\| \| \| \| \| \| \| \|	Hardcoded MMIO base addresses are used a few places throughout the platform code. Move these into the chip-specific header file so that adding support for new chips becomes a bit easier. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
*	avr32: Use <mach/foo.h> instead of <asm/arch/foo.h>	Haavard Skinnemoen	2008-08-05	1	-2/+2
\| \| \| \| \| \| \|	Update all avr32-specific files to use the new platform-specific header locations. Drivers shared with ARM are left alone for now. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
*	avr32: Power Management support ("standby" and "mem" modes)	Haavard Skinnemoen	2008-07-02	1	-0/+245
	Implement Standby support. In this mode, we'll suspend all drivers, put the SDRAM in self-refresh mode and switch off the HSB bus ("frozen" mode.) Implement Suspend-to-mem support. In this mode, we suspend all drivers, put the SDRAM into self-refresh mode and switch off all internal clocks except the 32 kHz oscillator ("stop" mode.) The lowest-level suspend code runs from a small portion of SRAM allocated at startup time. This gets rid of a small potential race with the SDRAM where we might try to enter self-refresh mode in the middle of an icache burst. We also relocate all interrupt and exception handlers to SRAM during the small window when we enter and exit the low-power modes. We don't need to do any special tricks to start and stop the PLL. The main clock is automatically gated by hardware until the PLL is stable. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
