- * The issue with this file is getting it loaded at the right place.
- * The first vector MUST be at address 0x????0100.
- * How this is achieved is dependant on the tool chain.
- *
- * However the basic mechanism for ELF assemblers is to create a
- * section called ".vectors", which will be loaded to an address
- * between 0x????0000 and 0x????0100 (inclusive) via a link script.
- *
- * The basic mechanism for XCOFF assemblers is to place it in the
- * normal text section, and arrange for this file to be located
- * at an appropriate position on the linker command line.
- *
- * The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the
- * offset from 0x????0000 to the first location in the file. This
- * will usually be 0x0000 or 0x0100.
