* linux/arch/arm/mach-omap1/board-generic.c
|
|
*
|
|
* Modified from board-innovator1510.c
|
|
*
|
|
* Code for generic OMAP board. Should work on many OMAP systems where
|
|
* the device drivers take care of all the necessary hardware initialization.
|
|
* Do not put any board specific code to this file; create a new machine
|
|
* type if you need custom low-level initializations.
