It is used to map custom memory up to 32MB.
 which means Force usage of a specific amount of
 memory Amount of memory to be used when the kernel is not
 ableto see the whole system memory or for test.

Hello,

Can anyone tell me what does "memmap" parameter means in boot arguments of
kernel? I am working on an embedded device which is running linux, and it
has the following parameter passed as boot argument :

mem=128M memmap=32M@128M

I don't know what it means. Can anyone explain??
   

Have  you read Documentation/kernel-parameters.txt ( [1] ) ?

thanks,
Daniel.
