Based on the definitive guide to EMIF configuration[1] certain registers
that we have been modifying (and are documented registers) should be
left in their reset values rather than modified. This has been tested
on AM335x GP EVM and Beaglebone White.

When core power domain hits oswr, then DDR3 memories does not come back
while resuming. This is because when EMIF registers are lost, then the
controller takes care of copying the values from the shadow registers.
If the shadow registers are not updated with the right values, then this
results in incorrect settings while resuming. So updating the shadow registers
with the corresponding status registers here during the boot.

Currently the DDR3 memory on DRA7 ES1.0 evm board is enabled using
software leveling. This was done since hardware leveling was not
working. Now that the right sequence to do hw leveling is identified,
use it. This is required for EMIF clockdomain to idle and come back
during lowpower usecases.

A board that has a USB ethernet device only may set the usbetheraddr
and not the ethaddr.
ethaddr will be the default MAC address that is chosen and if that
is not populated then the usbethaddr is looked at. If neither are set
then then device tree blob is not modified.

On further review, this change isn't helpful as our test environment
will likely blow away this information as part of ensuring an otherwise
known development environment, so just let them load the correct device
tree as needed.

This is a known issue on AM4372 that when there is a burst read to a
non-cacheable EMIF address space and the burst crosses 1K address boundary will
result in a hang. Since U-boot runs from DDR, there is a possibility that above
case occurs. So enable caches at the beginning of U-boot.
*This is a temporary fix and not meant for mainline.*

Commit "am335x: Enable RTC 32K OSC clock" describes the dependency
to enable RTC clks in bootloader. This is not true for AM4372.
In EPOS EVM RTC is not powered (VDDS_RTC grounded to 0). In GP EVM no
need to enble RTC in bootloader. So moving RTC enbling to its respective clock file.

Until we have device tree overlay support or something similar we need to
pass profile-specific device trees to the kernel. Update the logic to
expose a profile_number variable and update findfdt to use
am335x-evm-profileN.dtb. This is a TI SDK specific change as the answer
for upstream is to work towards device tree overlays or a similar
concept.

The DDR DQ lines are enabled with weak pull. So the DQ line was not staying at Vref
when IDLE (retreats to ground) and because of this there were extra transitions
and noise. So change from 0x64656465 to 0x64646464 to remove the weak pull.
Also internal VREF_DQOUT is set to 0. This has to enabled as well.
