[LinuxBIOS] The two load RAM codes.

[Feng, Libo]

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?
