Subject: [RFC,1/3] ARM: gemini: get platform to build again
|

There is no defconfig file for gemini, which has lead to a lot
|
|
of bitrot. This makes the broken board files, the gpio implementation
|
|
and the reset logic work again, and fixes the build warnings
|
|
that got introduced with the changes to the readl/writel prototypes.
