I am studying the LinuxBios project. I have a question about the RAM code: from
Makefile, it seems that LinuxBios could load codes from FLASH to RAM twice,
first for linuxbios_ram, second for so-called payload. My understanding is
correct or not. However, also from Makefile, it seems that linuxbios is
dependent on LINUXBIOS_RAM_ROM, but doesn't include it. The below is abstracted
from a Makefile for via epia-m based on LinuxBiosV2-2534:
linuxbios: crt0.o $(INIT-OBJECTS) $(LINUXBIOS_APC) $(LINUXBIOS_RAM_ROM)
ldscript.ld
$(CC) -nostdlib -nostartfiles -static -o $@ -T ldscript.ld crt0.o
$(INIT-OBJECTS)
$(CROSS_COMPILE)nm -n linuxbios | sort > linuxbios.map.
So, there is no action on LINUXBIOS_RAM_ROM. Does it mean linuxbios_ram is not
very important. Even without it, the system is also ok?
