Hi Aggrwal,
I could not understand common/memsize.c, how it works?
It writes markers at specific memory locations and then reads
these back. The algorithm is chosen to be fast but still to
be able to detect mirrored address ranges and other memory errors.
Suppose I configure

Hi,
Thanks for your patient explanation, I acquired a lot.
Glad if it helped.
I just find in linux, arch/mips/bcm47xx/prom.c, there is a segment code just
like what I suggest above.
And move the code to my old box which bootloader is redboot, it works well.
(Of
course I also tryed
hi~
thanks for your reply.
sorry for my ability of writing and understanding the code
=D
btw, How contribute my idea of this function, I means, it should be more
clean or easy just like this:
unsigned long get_ram_size(volatile long *base, long maxsize)
{
unsigned long mem;

Hi ya,

Like a charm ;)
maxsize / sizeof (long), what's meaning of it? why sizeof (long) is
dividend?
As the comment in line 50 states, cnt is used in pointer arithmetic,
so addr is increased in sizeof(long) bytes. maxsize however is
8 matches
