* Update Intel IXP4xx support
- Add IXP4xx NPE ethernet MAC support
- Add support for Intel IXDPG425 board
- Add support for Prodrive PDNB3 board
- Add IRQ support
Patch by Stefan Roese, 23 May 2006
[This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still
sufferes from licensing issues. Blame Intel.]

For this to work, the function definitions are + * contained in this header file. The "normal" use of inline functions + * is to use the inline functions in the module in which they are + * defined. In this case these inline functions are used in external + * modules and therefore the use of "inline extern". What this means + * is as follows: if a function foo is declared as "inline extern" this + * definition is only used for inlining, in no case is the function + * compiled on its own. If the compiler cannot inline the function it + * becomes an external reference. Therefore in IxQMgrQAccess.c all + * inline functions are defined without the "inline extern" specifier + * and so define the external references. In all other source files + * including this header file, these funtions are defined as "inline + * extern". + * + * + * @par + * IXP400 SW Release version 2.0 + * + * -- Copyright Notice -- + * + * @par + * Copyright 2001-2005, Intel Corporation. + * All rights reserved. + * + * @par + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

The "normal" use of inline functions + * is to use the inline functions in the module in which they are + * defined. In this case these inline functions are used in external + * modules and therefore the use of "inline extern". What this means + * is as follows: if a function foo is declared as "inline extern"this + * definition is only used for inlining, in no case is the function + * compiled on its own. If the compiler cannot inline the function it + * becomes an external reference. Therefore in IxQMgrAqmIf.c all + * inline functions are defined without the "inline extern" specifier + * and so define the external references. In all other modules these + * funtions are defined as "inline extern". + * + * + * @par + * IXP400 SW Release version 2.0 + * + * -- Copyright Notice -- + * + * @par + * Copyright 2001-2005, Intel Corporation. + * All rights reserved. + * + * @par + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
