We are booting the Linux kernel on T104xRDB Eval board. we are using QorIQ-SDK-T1040-BSP0.2-20140310-yocto SDK from Freescale. we are modifying the U-Boot to boot it from RAM. Like we have our own custom boot loader and that sets up the basic thing like law and DDR. So while we boot Linux from this ram U-Boot kernel panic is coming at bman_init as follows : if same kernel we boot form Flash U-boot it works fine. for RAM U-Boot we masked lot of law/tlb init code and for FMAN fimware we are using C array in U-Boot. so our ram based u-boot is able to load the linux and dtb files well but crashes.
