Hi All, We are trying to support 1GB SRAM for PMC. We are using MPC7447 Processor and MV64360/62 controller. To support this we are enabling high mem.When we give low mem as 0x40000000 and , it will hang in first statement i.e. while executing "go" command. We tried with diff values of low mem and kernel base.When low mem is 0x30000000 and Virtual addr of kernel base is 0xB0000000. Kernel is comming up but it will hang while executing execve(/sbin/init), which is in init/main.c
