| Subject: [PATCH] Allow access to low addresses with gcc 12 |
| |
| gcc 12 added a warning that triggers on access to low addresses. Add a |
| compile option that allows access to lower addresses. |
| |
| Add the 'cc_option' macro to avoid the compile option when the compiler |
| does not support it. |
| |
| This fixes build with TF-A. TF-A added a similar fix in commit |
| dea23e245fb89. |
| |
| See some more details in |
| https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105523 |
