Thanks. It set a byte in RAM and checked it using md.b in u-boot.

ok, now we can say the virt_to_phys returns a correct physical address.
0x32d01fe0. It is a physical address, not a simple offset in dram. Your 64Mb
dram has physical address within 0x30000000 ~ 0x34000000.

Kernel physical addr : 0x32d01fe0
Platform phys offset : 0x30000000
Page offset : 0xc0553fb4

The page offset looks weird, since 32bit kernel has 2/2 or 3/1 or 1/3
user/kernel virtual address  split. It is not reasonable to have
0xc0553fb4
as page offset. You should c0000000 for 3/1 split.

My fault. I had done "0x%llx" in printk. Now I just did a %x and it
shows as 0xc0000000.
