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
I believe you have a classic example of cut & paste here. AFAIK the Versatile board has no registers around that address. Perhaps the original author can answer your question.....
