Style changes. 2015-10-02 14:50:22 +00:00			`# Linker config. to produce a NEC PC-Engine 8K, 16K, or 32K image (.bin)`

Changed the PC-Engine's configuration file, so that the command line can build 8K, 16K, and 32K carts. Adjusted the PCE's document, the start-up code, and the PCE library test makefile. That makefile shows how to post-process the linker's output file. 2018-02-23 21:06:49 +00:00			`__CARTSIZE__: type = weak, value = $2000; # $2000, $4000, or $8000`
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. 2016-03-06 20:26:22 +00:00			`__STACKSIZE__: type = weak, value = $0300; # 3 pages stack`
