On da850, RTC alarm is a wakeup source from deep sleep.
Mark it as a wakeup source after the rtc platform device
is registered.
Without this patch, the rtc-omap driver suspends the RTC
during the suspend sequence and hence it cannot wakeup the
SoC.

This set of patches adds suspend-to-RAM support for DaVinci.
The support is presented as generic for DaVinci but has been
tested only on OMAP-L138. Hopefully extending it for other
SoCs is only a matter of adding SoC and board code.
Patch 12/14 adds the meat of the support; all previous patches
OMAP-L138 adds a second SYSCFG region having useful functionality
like deep sleep, pull up/down control and SATA clock stop.
This patch makes provision for accessing registers from second
SYSCFG region in da8xx code.
Note that OMAP-L137 has a single SYSCFG region.

As suspend support is added, the code supporting
the suspend operation needs to bypass PLLs and
needs to access the same wait time values as the
PLL code in clock.c.
To facilitate this, move the PLL wait times to
clock.h where they can be accessed by suspend code.

Move defintions of DDR2 controller registers to memory.h
from cpuidle.c. The motivation behind the change is to be
able to use these defintions in assembly code that puts
DDR2 in self-refresh and enables the SoC to enter suspend
state.

When suspend is supported, both cpuidle and suspend code
need to work on DDR2 registers. Instead of mapping the
DDR2 registers twice, do it once outside of cpuidle
driver and let cpuidle driver get the virtual base address
of DDR2 registers.

psc.h contains register defines for PSC module which
need to be accessed in assembly code which helps the
DA850/OMAP-L138 SoC go to sleep. Shutting down DDR clock
using PSC is a part of the sleep procedure.
Also, the PLL related hardware definitions in clock.h are
needed in assembly code to
The rtc-omap driver currently hardcodes the RTC to be
not capable of wakeup events. On the DA850/OMAP-L138
SoC, the RTC is a wake up source from its deep sleep
mode.
Let platform data set the wakeup capability flag instead.

The motivation behind the change is to use the same
definitions in the assembly code responsible for
suspending the SoC, a part of which is to clock gate
the DDR2 clock.
Note that the assembly code cannot invoke the C function
meant for this. The main reason being that stack in DDR2
cannot be
Create static map for internal SRAM and populate SRAM base
and size in soc_info structure to allow SRAM allocation
functions from arch/arm/mach-davinci/sram.c to work.
On DA850 SRAM is used for suspend-to-RAM implementation
in places where DDR2 cannot be accessed as its clocks are
stopped.
On omap-l1 devices the PLL registers can be locked from
writes. Currently the cpufreq rate setting code unlocks
PLL0 before the write actually happens. With suspend
support getting added PLL1 registers need be be unlocked
as well.
To facilitate this, unlock both PLLs during the init time
itself.
This patch adds core power management (suspend-to-RAM)
support for DaVinci SoCs.
The code depends on the the deepsleep feature to
suspend the SoC and saves power by gating the input
clock.
The wakeup can be based on an external event as
supported by the SoC.
Assembly code (in sleep.S) is added

Hello,
Here is the solution to my problem. Run the following command :
slh_DM646x.exe -load2DDR u-boot.bin -startAddr 0x8100 -loadAddr
0x8100
You have to specify the right startAddr and loadAddr options, depending
on your u-boot. Otherwise, you will get BOOTME after loading u-boot
