are still unsupported and will write warings on the second serial port.
- Fix elfloader_arch_write_rom (), which has to reside in a special bootloader
section of flash rom. The code is heavly inspired from avr-libc's documentation.
- Prelimiary implementation of elfloader_arch_allocate_rom: Code is
flashed to fixed address 0x8000. Note that on the AVR, flash rom is adressed
word (16bit)-wise, not byte wise!
- Preliminary implementation of elfloader_arch_allocate_ram using the mmem
module. Current code does not free the memory.
