Introduction
------------
The S3C2410 supports a low-power suspend mode, where the SDRAM is kept
The S3C24XX supports a low-power suspend mode, where the SDRAM is kept
in Self-Refresh mode, and all but the essential peripheral blocks are
powered down. For more information on how this works, please look
at the S3C2410 datasheets from Samsung.
at the relevant CPU datasheet from Samsung.

Note, the original method of adding an late_initcall() is wrong,
and will end up initialising all compiled machines' pm init!
The following is an example of code used for testing wakeup from
an falling edge on IRQ_EINT0:
static irqreturn_t button_irq(int irq, void *pw)
{
return IRQ_HANDLED;
}
statuc void __init machine_init(void)

Debugging
---------

care should be taken that any external clock sources that the UARTs
rely on are still enabled at that point.
3) If any debugging is placed in the resume path, then it must have the
relevant clocks and peripherals setup before use (ie, bootloader).
For example, if you transmit a character from the UART, the baud
rate and uart controls must be setup beforehand.
Configuration
-------------
@ -89,6 +116,10 @@ Configuration
Allows the entire memory to be checksummed before and after the
suspend to see if there has been any corruption of the contents.
Note, the time to calculate the CRC is dependant on the CPU speed
and the size of memory. For an 64Mbyte RAM area on an 200MHz
S3C2410, this can take approximately 4 seconds to complete.
This support requires the CRC32 function to be enabled.
