too big seabios (1MB)

Hello,

With debian unstable binutils 2.18 and 2.20 I always get quite big bios.bin.elf
Image. I believe it is because rom.o has alignes for 2**21

Yes this is default align on AMD64.

out/rom.o:     file format elf32-i386
out/rom.o
architecture: i386, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x000fdf9d

Program Header:
    LOAD off    0x000ef000 vaddr 0x000ef000 paddr 0x000ef000 align 2**21
         filesz 0x00011000 memsz 0x00011000 flags r-x

Not sure how to fix it?

I tried adding . = ALIGN(4096) to the linker script but it complains about
truncated relocs.

Rudolf and I fixed this earlier today.  For anyone else running into
this problem, please pull the latest SeaBIOS git.

There is a fix in the git tree that will allow the images to be used.
It's important to note that the bios.bin.elf will still be very large
- the change enables cbfstool to remove the extra pad that some
linkers add.
