Well!... You can pass the size as part of the OF memory=<>.

Typically your boot loader should detect the amount of memory on the
system and update the OF dtb to reflect the available memory.

You may also tweak the kernel yourself to autodetect, instead of reading
from the OF. How ever, I would recommend the previous approach.

Hi all,
    I am using the ppc405 and I would like to know, how does linux on
this architect detect the available memory size in details !!!
        is it a parameter passed to linux at startup by the boot loader
        is it an automatic detection ?? what are the steps to accomplish
this job then ???
Best regards to all,
