Hi All,

I am currently working on MIPS board. I have a 32MB RAM. 

The address that is shown in uboot when i type bdinfo if 0x80000000 and size
is 0x1000000(16MB).

I want to increase the size to 32 MB as board  has 32 MB RAM.

Interesting Finding:

When i write any data to  0x80000000 the same data is being written into
0x81000000. Same for all address in the range (data in 0x80000000 -
0x80ffffff is same as 0x81000000 - 0x81ffffff ).  It seems that there is a
dual mapping . 

What might be the reason?

Please help
