Hi,
This memory information is passed by the u-boot in bd_info structure (typedef
to bd_t).
Its defined in include/asm-ppc/ppcboot.h file.
First two parameters specify the start address and length.
Well, I'll at least try on my host x86 system. There is doesn't get from the
grub.
It should work and I should be able to see in cat /proc/meminfo.
I'll try and let you know.
Regards,
Parav Pandit

how to do this, I was wondering if you know how to "tell" the kernel how much
memory there is in the system. An example would be if I have 512MB of RAM, but
only want the system to know that there is about 500MB in RAM, so that 12MB
does not exist to the OS/kernel. Would this require mucking about in U-boot? or
can I just define this in the kernel source? Thanks

Most bootloaders including u-boot pass a board information structure that
includes a variety of information including the memory size.
Also I think top of memory is also typically passed to the Linux Kernel as
a register parameter by the boot loader.
