I am almost certain that the RAM memory is not initialized correctly.
I wrote a simple RAM test function which writes some pattern data into
0x0 - 0x400 address range and then reads it. The difference occurs
already at the first cell. There is 0x00, but should be 0xFF.
Conclusion is that RAM initialization for adl/msm800sev target is not valid.
