    Your failures highlighted in red are a result of the kernel module not installing correctly.

    The reason your cmemk.ko kernel module is not 'insmod'ing correctly is because it is configured to use memory that is owned by the Linux kernel.  The "overlaps kernel" message shows that you're trying to install cmemk.ko with 'phys_start=0x83c00000', but your kernel owns all memory from 0x80000000 - 0x84c00000).  The kernel owns that memory because you specified "mem=76M" in the u-boot bootargs parameter.

    You either need to reduce Linux kernel memory, specifying at most "mem=60M" in bootargs (since phys_start of 0x83c00000 corresponds to 60 MB), or increase cmemk.ko's phys_start to at least 0x84c00000 (by modifying the 'insmod cmemk.ko' command in loadmodules_hd.sh).
