I have the following in the linker definition file for protected code:
    SECTIONS {
    . = 0
    startup : {
        *(.startup)
        . = 0x1fc;
        LONG(0x87654321);
    } >flash
    prog : {
        *(.text)
        *(.rodata)
        *(.rodata*)
        *(.glue_7)
        *(.glue_7t)
    } >flash
etc. etc.

Assembler code in section ".startup" comes before the protection key
(0x87654321). Of course, it is my own responsibility to ensure that
this code takes less than 0x1fc bytes. Code generated by GCC in the
.text, .rodata and other sections come behind the protection key.

Kind regards,
