Some example cpu partition paths by name

ls -al /dev/block/platform/msm_sdcc.1/by-name/ [Qualcomm path]

ls -al /dev/block/pci/pci0000:00/0000:00:01.0/by-name/ [Asus Intel Atom]

ls -al /dev/block/platform/15570000.ufs/by-name/ [Samsung Exynos]

If you check above givn partition paths they are not the same for al cpu's it will be different as per the cpu's
so you need to search from here "/dev/block/" to find this folder "/by-name/" to get partition by name.
