actually trying on the tx25 board, and I see a hang after
the dram output too:

DRAM: 32 MiB

I inserted a breakpoint in start.S at clear_bss, never reached...

Maybe the fixloop

start.S:
[...]
fixnext:
str r1, [r0]
add r2, r2, #8 /* each rel.dyn entry is 8 bytes */
cmp r2, r3
ble fixloop
#endif
#endif /* #ifndef CONFIG_SKIP_RELOCATE_UBOOT */

clear_bss:

never reaches a end ... but just debugging it ...

register dump in fixloop:

TX25>ti;r
Core number : 0
Core state : debug mode (ARM)
Debug entry cause : Single Step
Current PC : 0x812000d8
Current CPSR : 0x800000d3 (Supervisor)
GPR00: 81fbe020 81fbe1a0 81224364 812285cc
GPR04: 81ebdf88 81ebdf8c 81fe6ac8 81fbe000
GPR08: 00000017 00dbe000 812285cc 00000000

PC : 812000d8 CPSR: 800000d3
TX25>

r2 and r3 are a multiple of 8, so this must end, but never
see it ending ...

bye,
Heiko
