|
* The architecture specific functionality for the Contiki ELF loader
|
|
* has to be implemented for each processor type Contiki runs on.
|
|
*
|
|
* Since the ELF format is slightly different for different processor
|
|
* types, the Contiki ELF loader is divided into two parts: the
|
|
* generic ELF loader module (\ref elfloader) and the architecture
|
|
* specific part (this module). The architecture specific part deals
|
|
* with memory allocation, code and data relocation, and writing the
|
|
* relocated ELF code into program memory.
|
|
*
|
|
* To port the Contiki ELF loader to a new processor type, this module
|
|
* has to be implemented for the new processor type.
