Hi there,
I just added new platform (at91) to my BSP and configured at91bootstrap
v3.8.9.
Problem is that PTXDist-2017.10 produces way too large binary:
2099622 at91sam9260ek-dataflashboot-barebox-3.8.9.bin
while correct size is:
2470 at91sam9260ek-dataflashboot-barebox-3.8.9.bin
Problem turned out to be ld-wrapper script or something it calls.
Just replacing ld-wrapper in ptxdist-2017.10.0/scripts/wrapper to point
directly to arm-v5te-linux-gnueabi-ld is enough to solve problem.
Does anyone clue where to look? Call path is:
sysroot-host/lib/wrapper in $PATH where
arm-v5te-linux-gnueabi-ld -> ptxdist-2017.10.0/scripts/wrapper/ld-wrapper
Thank you,
ladis

So, ld-wrapper is adding:

Modifying at91bootstrap's Makefile to do --remove-section=.note.gnu.build-id
fixes it.
Are there other options to fix this?

Well, I'll fix upstream the same way kernel handles this.
Kernel is always right: https://lkml.org/lkml/2011/12/15/162
Another option is to use u-boot way, ie. nicely align a embed
this section into binary, but as every byte matters here, lets
not do this.

You can also add TARGET_BUILD_ID to <PKG>_WRAPPER_BLACKLIST. We do the same
for the kernel.
