section ram_vectors 0 1 0 1 1 1 1 1 4010000 4010000 rom_vectors rom_vectors !The ram_vectors section is to allow some free space to copy vectors into from the ROM.  This is required to be variable size to accomodate SVT or MVT; 80 bytes vs 4kB.  Copying is not necessary with MVT, but it is optional because it may offer performance gains.  Copying is required for SVT because the (aligned) start of ROM contains initialization instructions.  RAM copy is used rather than leave a big gap in the ROM to get an aligned address for the trampoline code.  For RAM startup, ram_vectors will usually be of size zero, unless MVT and copying are enabled for memory estimation reasons.
