* Name: imx_memory_initialize
|
|
*
|
|
* Description:
|
|
* All i.MX6 architectures must provide the following entry point. This
|
|
* entry point is called early in the initialization before memory has
|
|
* been configured. This board-specific function is responsible for
|
|
* configuring any on-board memories.
|
|
*
|
|
* Logic in imx_memory_initialize must be careful to avoid using any
|
|
* global variables because those will be uninitialized at the time this
|
|
* function is called.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* None
