You are mis-reading the error, the CRC check is informing you that the
ramdisk is corrupt (aka it doesn't match the CRC). This is because
your ramdisk is 102MB, which will not fit between the memory range
0x6000000 to 0x7000000 (a 16MB segment). And when you load the dtb at
0x7000000 it will overwrite part of your rootfs image.

Just swap the addresses you are using for the dtb and rootfs, this
will make sure the rootfs has more than enough space to load into
memory.

Nathan
