问题：修复 IMX_SEC_ENCLAVE 和释放后使用依赖项。

Hello

这是对 GitHub 上这个 PR的后续跟进。

提供的补丁似乎最终没有应用，因为 lf-6.18.y 中没有这些补丁。

需要 Kconfig 提交来确保当 NVMEM_IMX_OCOTP_SCU 为 m 时 Enclave 驱动程序不能为 y，从而避免探测延迟。

否则你会看到这样的结果：

在提交的第二个版本中，驱动程序进行了一些重构，我不确定NXP是否已经解决了这个问题。

提交 9703dfecc735（“LF-15802：驱动程序：固件：imx：修复 SE 驱动程序移除”）

SE团队能否确认一下？

此致敬礼

Re: ISSUE: fix dependency for IMX_SEC_ENCLAVE and use-after-free

你好，

我看到这个问题还没有解决，我会和内部软件团队确认一下。

此致敬礼/Saludos，
阿尔多。
