set RAM start address to %S; add STARTADDRESS git-svn-id: svn://svn.cc65.org/cc65/trunk@3545 b7a2c559-68d2-44c3-8de9-860c34a00d81

Lower the default Atari start adress from $2E00 to $2000. With the startup memory check of the "system check" load chunk this should be fine

__EXEHDR__: type = import;
__SYSTEM_CHECK__: type = import; # force inclusion of "system check" load chunk
__AUTOSTART__: type = import; # force inclusion of autostart "trailer"
Reworked and improved the SYMBOLS section. The old syntax (using symbol = value) is now gone, attributes are used instead. The SYMBOLS section does now support imports, so the linker config can be used to force symbols (and therefore module) imports. Evaluation of start address and size for memory areas has been delayed even further, so it is now possible to use the values from one memory area in the definition of the next one. git-svn-id: svn://svn.cc65.org/cc65/trunk@4851 b7a2c559-68d2-44c3-8de9-860c34a00d81

MEMORY {
Renamed RAM to MAIN for all disk based targets. The name RAM doesn't make much sense in general for a memeory area because i.e. the zero page is for sure RAM but is not part of the memory area named RAM. For disk based targets it makes sense to put the disk file more into focus and here MAIN means the main part of the file - in contrast to some header. Only for ROM based targets the name RAM is kept as it makes sense to focus on the difference between RAM and ROM.

SEGMENTS {
Renamed INITBSS to INIT and INIT to ONCE. The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name. Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization.

Fixed INIT properties. The main chunk load header references __BSS_LOAD__ so BSS must be the first bss type segment. Subsequent changes will move ONCE to share its address with the BSS. Then it'll be necessary to load INIT from disk. Therefore we do it right now.
