* Name: imx_cpu_disable
*
* Description:
* Called from CPU0 to make sure that all other CPUs are in the disabled
* state. This is a formality because the other CPUs are actually running
* then we have probably already crashed.
*
* Input Parameters:
* None
*
* Returned Value:
* None

* Name: imx_cpu_enable
*
* Description:
* Called from CPU0 to enable all other CPUs. The enabled CPUs will start
* execution at __cpuN_start and, after very low-level CPU initialization
* has been performed, will branch to arm_cpu_boot()
* (see arch/arm/src/armv7-a/smp.h)
*
* Input Parameters:
* None

* 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

void imx_memory_initialize(void);
* Name: imx_board_initialize
*
* Description:
* All i.MX6 architectures must provide the following entry point. This
* entry point is called in the initialization phase -- after
* imx_memory_initialize and after all memory has been configured and
* mapped but before any devices have been initialized.
*
* Input Parameters:
* None
*
* Returned Value:
* None
