- * Several Sun color frame buffers use some kind of Brooktree video
- * DAC (e.g., the Bt458, -- in any case, Brooktree make the only
- * decent color frame buffer chips).
- *
- * Color map control on these is a bit funky in a SPARCstation.
- * To update the color map one would normally do byte writes, but
- * the hardware takes longword writes. Since there are three
- * registers for each color map entry (R, then G, then B), we have
- * to set color 1 with a write to address 0 (setting 0's R/G/B and
- * color 1's R) followed by a second write to address 1 (setting
- * color 1's G/B and color 2's R/G). Software must therefore keep
- * a copy of the current map.
- *
- * The colormap address register increments automatically, so the
- * above write is done as:
- *
- * bt->bt_addr = 0;
- * bt->bt_cmap = R0G0B0R1;
- * bt->bt_cmap = G1B1R2G2;
- * ...
- *
- * Yow!
- *
- * Bonus complication: on the cg6, only the top 8 bits of each 32 bit
- * register matter, even though the cg3 takes all the bits from all
- * bytes written to it.
