Subject: [PATCH] fix(build): allow lower address access with gcc-12
|
|
|
|
With gcc-12 any lower address access can trigger a warning/error
|
|
this would be useful in other parts of system but in TF-A
|
|
there are various reasons to access to the lower address ranges,
|
|
example using mmio_read_*/writes_*
|
|
|
|
So setup to allow access to lower addresses while using gcc-12
|
|
