i'm setting a rule that each section *has* to have a list of clear<br>
benefits, otherwise it'll have to be removed before it goes on to<br>
their Directors.<br>
<br>
so - even if there are any allwinner engineers reading this who would<br>
like something put forward please also speak up! :)<br>

<div>1) current using fdt in bootloader(uboot) is not mature, I'm not saying about passing the fdt data to kernel.</div><div> But the bootloader itself need information from device tree, say boot0/1 phase (boot device type, DDR initialization...)</div>
<div> since fdt is not ready, and SRAM space is very limited ... I'm afraid 'fex' may co-exist with device tree.</div><div> still, they receive benefits if they can adopt device tree, at least minimal the kernel side migration effort</div>
<div> Generally this info already been pointed<span></span> out by steppen warren in previous email...</div><div><br></div><div>2) device tree may not been understood by third vendors (who previus produce shoes or ? :-$), </div>
<div> they are real old 'Fex' scheme user, they like edit the data in windows with dos format</div><div> So, how to fill this gaps, make them happy? Creat another tool to handle device tree modification?</div><div>
Then it's another price they have to pay...</div><div><br></div><div><br></div><div>Dennis Lan</div>
