Hi All,
any suggestions ?
how does memory probe work ? any sample code one can point to ?
any dependencies in doing this one has on sdram memory configuration
controller registers ? as I am not too sure if ixdp425 controller has
this option also ?
Cheers,
Alfred

Hi,
I have a perhaps basic question on redboot.
Is redboot able to probe the actual physical memory on board and pass
it on linux command line ?
I could only see the #define which fix'es the installed memory.
Say we have 2 versions of board, with different h/w memory configurations,
how can we probe and pass to linux kernel the correct mem=XXX size.
Please point to me the reference code / exisiting code / any patch
which has such memory detection thing.
( I know it can be done, as I have done it once on netbsd plattform
from user plane memory chips register reading and all )
Cheers,
Alfred
