Subject: [PATCH] Makefile: (re-)enable A53 errata workaround
|
||
|
|
|
||
|
|
The --fix-cortex-a53-843418 option to the linker was disabled before to
|
||
|
|
also support older toolchains which don't know of this option.
|
||
|
|
To not loose the bugfix for more recent toolchains introduce a feature
|
||
|
|
check, which enables the option if the linker knows about it.
