[U-Boot] "WARNING: adjusting available memory to 0x30000000"

Hi,

I am using customized ppc440 based board with DDR3 memory 1 GB. While running u-boot I observed the warning message :* "WARNING: adjusting available memory to 0x30000000".*

I observed that the macro CONFIG_SYS_LINUX_LOWMEM_MAX_SIZE is set to 768 MB which is less than 1GB. Hence the available memory is set to * 0x30000000.

*Please help me out to resolve this warning message.
