[By Steven Scholz <steven.scholz@imc-berlin.de>, 16 Aug 2004] Since the cpu/ directory gets clobbered with peripheral driver code I |

started cleaning up arch/arm/cpu/arm920t. |

I introduced the concept of Soc (system on a chip) into the ./cpu directory. That means that code that is cpu (i.e. core) specific resides in |

$(CPUDIR)/ |

and code that is specific to some SoC (i.e. vendor specific peripherals around the core) is moved into |

$(CPUDIR)/$(SOC)/ |

Thus a library/archive "$(CPUDIR)/$(SOC)/lib$(SOC).a" will be build |

One can select an SoC by passing the name of it to ./mkconfig just like @./mkconfig $(@:_config=) arm arm920t vcma9 mpl s3c24x0 If there's no VENDOR field (like "mpl" in the above line) one has to pass NULL instead: @./mkconfig $(@:_config=) arm arm920t mx1ads NULL imx |
