No need this comment because we know _fb_ means frame buffer...

How about to use goni_fb_win[] array so that can be extended easily...

If possible, please keep the align like below...for easily reading...
But...it depends on your taste...:-)

+	.win_mode = {
+		.pixclock	= 1000000000000ULL /
((16+16+2+480)*(28+3+2+800)*55),
+		.left_margin	= 16,
+		.right_margin	= 16,
+		.upper_margin	= 3,
+		.lower_margin	= 28,
+		.hsync_len	= 2,
+		.vsync_len	= 2,
+		.xres		= 480,
+		.yres		= 800,
+		.refresh		= 55,
+	},
+	.max_bpp	= 32,
+	.default_bpp	= 16,

Same...as previous comment.

no need above empty line.
