Thank you Jerry,

This removes some magic!
Do you know by any chance what the reason can be for

Loading u-boot.bin , please wait ....
# PPC: timeout while waiting for freeze
*** TARGET: reset detected, restarting target

I have HRCW 0x0E74B20A, (ISB100), so I have changed my BDI config
; init core register
WREG    MSR             0x00001002      ;MSR  : ME,RI
WM32    0xF0010004      0xFFFFFFC3      ;SYPCR: disable watchdog
WM32    0xF00101A8      0x04700000      ;IMMR : internal space @ 0x04700000

'md', some other commands work fine but 'load' is 'timing out'?
u-boot as stand alone starts without problems (HRCW come from flash), 
BDI is not resetting anymore apart from case when I do 'load'.
