</div>You don't need to do it in lowlevel init, just before registering the<br>
cfi device is enough. Usually it's good habit to do only the absolutely<br>
necessary things in lowlevel init. Doing things later increases the<br>
chance that you get useful debug output when something goes wrong<br>
<div class="HOEnZb"><div class="h5"><br></div></div></blockquote><div>I read the different board initialization routines over and over again, but can't find a common pattern. From what I see the lowlevel_init (which has been converted nicely into a C file), only AIPS, MAX, MPLL core clock, all clocks, SDRAM are initialized, but I have seen AIPS and MAX setups in core_init functions (eukrea_cpuimx35.c), as well as clock setups in console_init and other places. So, what's the bare minimum in lowlevel to set up? SDRAM/MDDR? What's the order of things? </div>
