Only MTD device name for mount rootfs, like that "rootfs=3D/dev/mtdblock/0"
: Example hints file also in attachment.
: In this example one of partitions (0x00040000-0x003e0000) split by keywor=

about this syntax. Are the characters '-' '-' 'P' 'a' 'C' 'k' 'I' 'm'
'G' 's' '-' '-' at the start of one of the partitions?
Yes. D-Link DIR-320 (cpu BCM5354) load kernel and rootfs in single file whi=
ch have:
1. image header (image magic, size, CRC etc.)
2. Kernel
3. keyword '--PaCkImGs--' as a delimeter between kernel and rootfs
4. And rootfs
In different firmware different size of kernel and different rootfs offset.
