TDA4VM: TDA4 ddr initialization fails in SBL

Part Number: TDA4VM

session_ttyusb2_2022-11-15-2.log

HI Ti:

We found two problems with the initialization of the ddr on the user board,One is that the initialization fails occasionally, the other is that the initialization succeeds but the data is flipped occasionally at custom board. use v0.9.1 tools and change DQ training  0x10200000 > 0x10400000 & 0x0c002007 > 0xC002006

1. initialization fails occasionally

2. data is flipped occasionally

Can you suggest which parameters need to be adjusted? E.g. DDR ODT?, etc
