ADSP-219x DSP Multiple .DXE Support

VisualDSP++ 3.5 introduces support for multiple
EPROM booting mode. Boot streams of multiple projects or applications
can be stored in a single EPROM. The on-chip boot kernel always boots
in application number 0. Its boot stream starts at EPROM address
. User-defined second-stage loaders or boot management soft-
0x000000
ware may boot any application depending on application-specific
circumstances. Alternatively, one application can be loaded and executed
after the other terminates. The loader/splitter utility can consume multi-
ple files and arrange their boot streams in several manners.
.DXE
Use the following syntax to submit two or more executable files to the
loader:
