[U-Boot] Boot failure with a AT91RM9200 based custom board

Greetings,
I'm looking for a AT91RM9200 specialist as I've got stuck porting board
support from a old u-boot (v1.1.4) to the latest stable (v2016.07)...
I'm using the at91r9200ek board as a template to get things running...
With the patches i can get to the state below and here the board hangs.
When patch 0004 is omitted, it seems the board doesn't boot at all (I'm
basing this assumption on the current consumption of the system).
The console shows the following...
initcall: 1001cce0
U-Boot 2016.07-g95a02a7 (Aug 12 2016 - 01:43:34 +0200)

initcall: 1000b424
New Stack Pointer is: 23f23ed0
initcall: 1000b6ac
initcall: 1000b640
Relocation Offset is: 13f84000
Relocating to 23f84000, new gd at 23f23ef0, sp at 23f23ed0
Some detail about the board:
AT91RM9200; external boot from /CS0
64Mbyte SDRAM (32bit)
32Mbyte NOR (16bit)

Any ideas, pointers, even flame is appreciated. If more info is needed
I'm happy to deliver
Thanx in advance.
Cheers, Peter
