|
|
* evm for a given OMAP5 revision, this information is kept

|

|
|
*
|
|
* For any new board with different memory devices over-ride one or more
|
|
* of the following functions as per the CONFIG flags you intend to enable:
|
|
* - emif_get_reg_dump()
|
|
* - emif_get_dmm_regs()
|
|
* - emif_get_device_details()
