Message-ID: <1183116085.3126.23.camel@odpc49> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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
