Subject: [U-Boot] [PATCH 2/2] video: bcm2835: fix various output modes
Date: Tue, 22 Oct 2013 22:27:21 +0200 [thread overview]
Message-ID: <1382473641-20614-2-git-send-email-a.heider@gmail.com> (raw)
Depending on the firmware's video options [1] the active SDTV or
HDTV mode can yield a framebuffer with noncontiguous horizontal lines,
giving a messed up display, for both, u-boot and the loaded kernel.
To always archive the required contiguousness for the used 16bpp, round
the framebuffer width down so its aligned to a width of 16.
