From c24e58f599085efa79a61cb62170b6b2164b8ce9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 24 Apr 2022 23:31:04 -0600 Subject: [PATCH] fs: Add a function to set the filesystem type When sandbox is used with hostfs we won't have a block device, but still must set up the filesystem type before any filesystem operation, such as loading a file. Add a function to handle this.
