Subject: [PATCH 19/27] MIPS: ath79: Store the SoC revision in a global variable
|
||
|
|
|
||
|
|
Knowing the exact revision of the SoC is required to make runtime decisions
|
||
|
|
in various code paths. We have determined the SoC revision already, so we
|
||
|
|
only need to store that in a global variable.
