Which stage auto.c
E0: 0xff010003 -->  0x06000003
E4: 0x09070103 -->  0x09070103
E8: 		     -->   0x0c0a0203

I mean when enumerating HT0 e0 is set to 0xff010003, while e4 matains 
0x09070103,
so e4 overlaps with e0?

In auto.c setup_myboard_resource_map():
E0: <- 0x06000003
E4: <- 0x09070103
E8: <- 0x0c0a0203

then in C part amdk8_scan_chains():
E0: <- 0xff010003 (max=0)    /* E0 overlaps E4/E8 ? */
max = hypertransport_scan_chain(link0, max);
E0: <- 0x06010003 (imagin max=0x6)
E4: <- 0xff070003        /* E4 overlaps E8 ? */
max = hypertransport_scan_chain(link1, max);
E4: <- 0x09070003 (imagin max=0x9)
E8: <- 0xff0a0003
max = hypertransport_scan_chain(link2, max);
E8: <- 0x0c0a0003 (imagin max=0xc)
