[U-Boot-Users] ARM9: Reset hw/reg @0xfffece10?

Hi,

I am working on an u-boot port for an ARM926EJ-S based SOC (SVENm).

Implementing the 'reset' cmd I tried to understand what other 
ARM9 CPUs do there.
There is some similar code for reset_cpu() in:
cpu/arm925t/start.S:422:        ldr     r1, rstctl1     /* get clkm1 reset ctl */
cpu/arm926ejs/omap/reset.S:36:  ldr     r1, rstctl1     /* get clkm1 reset ctl */
cpu/arm926ejs/versatile/reset.S:36:     ldr     r1, rstctl1     /* get clkm1 reset ctl */
cpu/arm946es/start.S:398:       ldr     r1, rstctl1     /* get clkm1 reset ctl */

which all refers to 
rstctl1:
         .word   0xfffece10

I looked in various docs (Versatile, ARM926, ...), but did not find any
reference to hw at 0xfffece10.

Could anyone please point me to a document which describes the hw/reg
found there?

Regards,
Josef
