Subject: [PATCH] firmware: bcm47xx_nvram: inline code checking NVRAM size
|
|
MIME-Version: 1.0

Separated function was not improving code quality much (or at all).
|
|
Moreover it expected possible flash end address as argument and it was
|
|
returning NVRAM size.
|
|
|
|
The new code always operates on offsets which means less logic and less
|
|
calculations.
