Subject: hw/sd: sd: Skip write protect groups check in sd_erase() for high
capacity cards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 2473dc4022458dcc05ec367ce97edbef29d7e50c
References: bsc#1175144, CVE-2020-17380, bsc#1176681, CVE-2020-25085
References: bsc#1182282, CVE-2021-3409
High capacity cards don't support write protection hence we should
not perform the write protect groups check in sd_erase() for them.
