[U-Boot] WARNING: adjusting available memory to 30000000

Hi,

I am using customized ppc440 based board having 4GB DDR3 memory.

While running u-boot I am getting “WARNING: adjusting available memory to 30000000” messege.

Further debugging I came to know that CONFIG_SYS_LINUX_LOWMEM_MAX_SIZE is set to 0x30000000 and my ddr size come to 0x40000000

Please let me know is u-boot supports upto 0x30000000 or I can modify CONFIG_SYS_LINUX_LOWMEM_MAX_SIZE macro to 0x40000000. Regards,Ronny
