Subject: sandbox: Use the reset driver to handle reset
X-Git-Tag: v2015.10-rc1~127
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=5010d98f02d9714f83c507e12ade0c52d214d157;p=u-boot

sandbox: Use the reset driver to handle reset

Move sandbox over to use the reset uclass for reset, instead of a direct
call to do_reset(). This allows us to add tests.
