Subject: fastboot: getvar: Add "is-userspace" variable
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=139db354b18014e224068a4f2b3b95e025812b17;p=u-boot.git

fastboot: getvar: Add "is-userspace" variable

As per documentation [1], Android-Q requires for bootloader to provide
"is-userspace" variable. "no" value should be always returned. This
patch implements this fastboot variable.
