I have found an issue what is crashing with the running from ram.
There is machine check on reading data.The MCSR register bit is BUS_RBERR (read data bus error).
MCSR = 00000008
MCSRR0 = 0116C8E8
MCSRR1 = 00005600
MCAR = 20090000
On my board it happens every time booting with the board with bootrom attached.
