Hi, I just tried to build openbios-qemu.elf, but it is a little too big
(1MB + 4 bytes):
Elf file type is EXEC (Executable file)
Entry point 0xfff08000
There are 3 program headers, starting at offset 52
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x000094 0xfff00000 0xfff00000 0x100000 0x100000 RWE 0x4
LOAD 0x100094 0xfffffffc 0xfffffffc 0x00004 0x00004 R E 0x1
GNU_STACK 0x000000 0x00000000 0x00000000 0x00000 0x00000 RWE 0x4
Section to Segment mapping:
Segment Sections...
00 .text.vectors .text .rodata .data .sdata .bss .sbss
01 .romentry
02
In contrast, the openbios-ppc binary in qemu looks like this:
Elf file type is EXEC (Executable file)
Entry point 0xfff08000
There are 2 program headers, starting at offset 52
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x000074 0xfff00000 0xfff00000 0x41044 0x4bc44 RWE 0x4
LOAD 0x0410b8 0xfffffffc 0xfffffffc 0x00004 0x00004 R E 0x1
Section to Segment mapping:
Segment Sections...
00 .text.vectors .text .rodata .data .sdata .bss .sbss.1 .sbss.2 .sbss.3 .sbss.4 .sbss.5 .sbss.6 .sbss.7 .sbss.8
01 .romentry
I'm building with gcc 4.2.3. Any ideas?
