|

* DESCRIPTION:
|
||||
* Basic initialization for Phytec LPC3180 board.
|
||||
* Note: This code assumes that basic processor initialization is
|
||||
* already done (e.g. SDRAM, clock etc. ). This can be done
|
||||
* e.g. by bootloader (U-Boot). We only do basic system
|
||||
* initialization most probably not done by bootloader here.
