    uboot-mvebu: backport LibreSSL patches for older version of LibreSSL
    
    If you would like to compile the newest version of U-boot together with the stable
    OpenWrt version, which does not have LibreSSL >= 3.5, which was updated
    in the master branch by commit 5451b03b7ceb2315445c683fe174e28bbdd49c2f
    ("tools/libressl: bump to v3.5.3"), then you need these two patches to
    fix it. They are backported from U-boot repository.
    
    This should be backported to stable OpenWrt versions.

+Subject: [PATCH 2/2] tools: mkimage: fix build with recent LibreSSL
+
+LibreSSL 3.5.0 and later (also shipped as part of OpenBSD 7.1 and
+and later) have an opaque RSA object and do provide the
+RSA_get0_* functions that OpenSSL provides.
