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