+Subject: [PATCH] bootsplash: Increase heap from 1 MB to 4 MB when bootsplash
+ is enabled
+
+Since commit 1d029b40c9de ("lib/jpeg: Replace decoder with Wuffs'
+implementation"), a relatively large heap allocation is needed to
+decode many JPEGs for use as work area.  The prior decoder did not need
+this, but also had many limitations in the JPEGs it could decode.
+
+A 1024x768 non-progressive JPEG used in Heads needs 1179648 bytes of
+work area; about 1.2 MB.  While the work area will also depend on the
+subsampling of each channel, it's generally proportional to the image
+size.
+
+Increasing the heap size to 4 MB when bootsplash is enabled should be
+enough to decode bootsplashes up to 1920x1080 with some headroom.
