Can anyone help me suggest a  partition layout for this router?

It doesn't seem right to me.
Output of df and du?
What is the router (it might be in the above, but it is harder to read it than ask you!)

Information from uboot printenv:
Flash base address: 0xB0000000
uboot:
address 0xB0000000 (= offset 0x0)
size 10000

rootfs:
address 0xB0010000 (=offset 0x10000)
size ???

kernel:
address ???
size ???

sysconfig:
address 0xB07EE000
size 0x10000

ubootconfig (uboot-env?):
address 0xB07FE000 (=offset 0x7FE000)
size 0x1000

fwdiag:
address 0xB07FF000 (=offset 0x7FF000)
size 0x1000

Kernel and Rootfs are of dynamic size, so there is just the static offset of 0x10000. On other devices I know, those two partitions are referenced as the Firmware partition. If you need static sizes, choose around 1 MB for the kernel and the rest for rootfs.

Somehow adapted from the old 1043 config, that could look like this:

static struct mtd_partition gr7000_partitions[] = {
    {
        .name        = "uboot",
        .offset        = 0,
        .size            = 0x010000,
        .mask_flags    = MTD_WRITEABLE,
    }, {
        .name        = "kernel",
        .offset        = 0x010000,
        .size            = 0x140000,
    }, {
        .name        = "rootfs",
        .offset        = 0x150000,
        .size            = 0x69e000,
    }, {
        .name        = "sysconfig",
        .offset        = 0x7ee000,
        .size            = 0x010000,
        .mask_flags    = MTD_WRITEABLE,
    }, {
        .name        = "uboot-env",
        .offset        = 0x7fe000,
        .size            = 0x01000,
        .mask_flags    = MTD_WRITEABLE,
    }, {
        .name        = "fwdiag",
        .offset        = 0x7ff000,
        .size            = 0x01000,
        .mask_flags    = MTD_WRITEABLE,
    }, {
        .name        = "firmware",
        .offset        = 0x010000,
        .size            = 0x7de000,
    }
};

Thanks

The discussion might have continued from here.
