From dd8a29040dec1566c567e5d8c39456bd0f49e01d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 22 Feb 2023 09:34:04 -0700 Subject: [PATCH] sandbox: Tidy up RTC options At present we enable the sandbox RTC driver for all builds. Add a separate Kconfig option to control this, so that it can be disabled in TPL, where it is not needed.
