Support full hex file format (serial_load & emulator)

jbush001 commented 5 years ago

The current hex file loader is simplistic. As defined in IEEE 1364-2001, section 17.2.8:

"The text file to be read shall contain only the following:

White space (spaces, new lines, tabs, and form-feeds)'
Comments (both C++ comment styles are allowed, / / and //)
Binary or hexadecimal numbers ... The unknown value (x or X), the high impedance value (z or Z), and the underscore (_) can be used in specifying a number as in a Verilog HDL source description. White space and/or comments shall be used to separate the numbers. ... When addresses appear in the data file, the format is an at character ( @) followed by a hexadecimal number as follows: @ hh...h"

Currently, to support binaries that don't start at address 0 (OS kernels), the elf2hex tool in the NyuziToolchain repo takes a parameter that specifies the base address offset (-b). The @ addressing format would allow removing this parameter.
