* mediadrm
* Whose friendly names do not match the #define statements.
*
* Additionally, AID_OEM_RESERVED_START and AID_OEM_RESERVED_END
* can be used to define reserved OEM ranges used for sanity checks
* during the build process. The rules are, they must end with START/END
* The proper convention is incrementing a number like so:
* AID_OEM_RESERVED_START
* AID_OEM_RESERVED_1_START
* AID_OEM_RESERVED_2_START
* ...
* The same applies to the END.
* They are not required to be in order, but must not overlap each other and
* must define a START and END'ing range. START must be smaller than END.
* This file must only be used for platform (Google managed, and submitted through AOSP), AIDs. 3rd
* party AIDs must be added via config.fs, which will place them in the corresponding partition's
* passwd and group files. There are ranges in this file reserved for AIDs for each 3rd party
* partition, from which the system reads passwd and group files.
