[ARM] 4600/1: fix kernel build failure with build-id-supporting binutils
|
|
|
|
Newer versions of binutils support --build-id, which adds an ELF
|
|
note section called ".note.gnu.build-id" to the output. On the ARM
|
|
kernel build, because there is no explicit mention of this section
|
|
in the shipped ld script, this section is placed at vaddr 0x00000000
|
|
(whereas the normal kernel text/data typically starts at vaddr
|
|
0xc0008000), causing the output of objcopy (Image) to produce a 3G+
|
|
file.
|
|
|
|
This patch makes objcopy strip the .note.gnu.build-id section from
|
|
the Image file along with all other note sections, which fixes the
|
|
build.
