From d41de2ea7a65242f5c95e578d99cf46cd23920dd Mon Sep 17 00:00:00 2001 From: "Ronald G. minnich" Date: Tue, 16 Jun 2009 15:02:52 +0000 Subject: These changes implement car in qemu. The implementation is in several ways superior to v3, while lacking its completeness. But, one nice thing: no more included .S or .c files. It's all separate compilation. That should allow our Makefiles to work much better. Note that the current non-CAR implementation is the default and continues to work (tested FILO boot to Linux on both CAR and non-CAR). Index: src/mainboard/emulation/qemu-x86/Config.lb Change this to be sensitive to USE_DCACHE_RAM. All settings etc. that depend on this variable are grouped in one if, and the other parts (romcc etc.) are in the else. This change is a model of how we should be able to do other motherboards. Index: src/mainboard/emulation/qemu-x86/Options.lb add needed options. Index: src/mainboard/emulation/qemu-x86/failover.c remove code inclusion from this not-yet-used file. Index: src/mainboard/emulation/qemu-x86/rom.c This is the entry point for the rom-based code. Called stage1.c in v3. Index: src/lib/Config.lb change initobject to a .o from a .c; this fixed a build problem. Index: src/pc80/serial.c make uart_init non-static. Index: src/pc80/Config.lb add initobject Index: src/arch/i386/init/entry.S Entry point. Unify a bunch of files that were fiddly lttle includes. From v3. Index: src/arch/i386/init/ldscript.ld new file. The goal is to hang all init changes for CAR here, to minimize other changes to any other ldscript. Besides, putting this in init makes sense; entry and car are manage init. Index: src/arch/i386/init/car.S generic i386 car code from v3. Index: src/arch/i386/init/ldscript_fallback_cbfs.lb Fix what looks like a bug: this was not including the init.text section. Index: targets/emulation/qemu-x86/Config.lb push up the console loglevel. qemu is for debugging so we might as well get all the debugging we can. Index: targets/emulation/qemu-x86/Config-car.lb For CAR bullds.
