Subject: fs: Add a function to set the filesystem type
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=c24e58f599085efa79a61cb62170b6b2164b8ce9;p=u-boot.git

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.
