OK, I did some more research - my SDRAM config is
PHYS_SDRAM_1            0xa0000000
PHYS_SDRAM_1_SIZE       0x04000000
CFG_DRAM_BASE           0xa0000000
CFG_DRAM_SIZE           0x04000000

those memory errors mentioned in earlier post do 
not appear if I change CFG_MEMTEST_END from 
0xa3efffff (- 63M) to 0xa3dfffff (- 62M). 
CFG_MEMTEST_START = 0xa0100000 (1M -). In 
config.mk TEXT_BASE = 0xa3f00000.

at bootup uboot displays
U-Boot code: A3F00000 -> A3F177B8  BSS: -> A3F1BAD8

Is there some uboot relevant stuff between 
0xa3efffff - 0xa3dfffff that I run over when doing 
mtest on all 63Mb? Code and stack seem to be safe.
