From: Simon Glass Date: Sun, 1 Sep 2024 22:26:33 +0000 (-0600) Subject: test: mbr: Use RAM for the buffers X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=6cfc777b9695003c4303a9e61194fe2c64af40e3;p=u-boot.git test: mbr: Use RAM for the buffers The normal approach with sandbox is to use a fixed memory address in the RAM, to avoid needing to create a map for transient local variables. Update this test to use this approach.
