From: Tom Rini Date: Mon, 15 Jul 2024 11:42:00 +0000 (+0100) Subject: bootstash: Do not provide a default address for all X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=b81e31a1e6c5e0b20537fa8ffba67696dec46d58;p=u-boot.git bootstash: Do not provide a default address for all A valid memory location to stash bootstage information at will be architecture dependent. Move the existing defaults to the main Kconfig file for this option and set 0x0 as the default only for sandbox.
