Subject: sandbox: Report host default-filename in native mode
X-Git-Url: http://git.dujemihanovic.xyz/html/static/%7B%7B%20%24.Site.BaseURL%20%7D%7Dposts/index.xml?a=commitdiff_plain;h=7506c1566998d188867423bd184a9dd00a9246c4;p=u-boot.git

sandbox: Report host default-filename in native mode

When the --native flag is given, pretend to be running the host
architecture rather than sandbox.

Allow the same control for PXE too.
