在Android系統中，如何確認SoC的信息？可以查詢/proc/cpuinfo
$ cat /proc/cpuinfo
processor : 0
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xd03
CPU revision : 2
...
Hardware : Qualcomm Technologies, Inc MSM8994
如何確認各個分區是掛載到哪個目錄下的？在/dev/block/platform/soc目錄下找到by-name
$ ls -l /dev/block/platform/soc.0/f9824900.sdhci/by-name/
