86ef66d977 arm-uboot: Make self-relocatable to allow loading at any address 2016-02-27 13:40:52 +01:00

5bcb7d394c Allow _start == 0 with relocatable images 2016-02-27 13:35:36 +01:00

df21fff504 Provide __bss_start and _end symbols in grub-mkimage. 
For this ensure that all bss sections are merged.

We need this to correctly prelink non-PE relocatable images.

73a9c742fe Encapsulate image layout into a separate structure. 
Currently we pass around a lot of pointer. Instead put all relevant data
into one structure.

dd3969e7ec mkimagexx: Split PE and generic part for relocations. 
As a preparation for U-Boot relocations, split emitting PE-relocations
from parsing source ELF-relocations.

36212460d3 mkimage.c: Split into separate files. 
util/grub-mkimagexx.c is included in a special way into mkimage.c.
Interoperation between defines makes this very tricky. Instead
just have a clean interface and compile util/grub-mkimage*.c separately
from mkimage.c

1018e91dce mkimage: zero fill alignment space 
This did not cause real problem but is good for reproducible builds. I hit
it with recent bootinfoscript that displays embedded config; I was puzzled
by random garbage at the end.

Prezero memory buffer used to assemble core.img. This makes individual
memset redundant. Also ensure buffer is filled with zeroes in several other
places.

Also remove redundant zeroing code where we fill in the whole memory block
anyway.
