Subject: common: spl: spl: Remove video driver before u-boot proper
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-logo.png?a=commitdiff_plain;h=7a17e4c6f1019296a12fc68005916f11de6db928;p=u-boot.git

common: spl: spl: Remove video driver before u-boot proper

Add method to remove video driver before loading u-boot proper. When
bootstage changes from SPL to u-boot proper, noo method is called to
remove video driver, and at u-boot proper if video driver is not
enabled, the video driver starts displaying garbage on the screen,
because there is no reserved space for video and the frame buffer gets
u-boot proper data written.
