- * The Papyrus ELF link scripts support three special sections:
- * .entry The actual entry point, this must contain less
- * than 256 bytes of code/data to fit below the
- * .vectors section. This always preceeds any other
- * code or data.
- * .vectors The section containing the interrupt entry veneers.
- * .entry2 Any code overflowing from .entry
- * .descriptors The PowerOpen function indirection blocks.
- */
-
-/*
- * Downloaded code loads the vectors separately to 0x00000100,
- * so .entry can be over 256 bytes.
- *
- * The other sections are linked in the following order:
- * .entry
- * .entry2
- * .text
- * .descriptors
- * .data
- * .bss
- * usually starting from 0x00020000.
- *
- * The initial stack is set to run BELOW the code base address.
- *
- * All the entry veneer has to do is to clear the BSS.
