 /*
- * Generate a CVT standard mode from HDisplay, VDisplay and VRefresh.
- *
- * These calculations are stolen from the CVT calculation spreadsheet written
- * by Graham Loveridge. He seems to be claiming no copyright and there seems to
- * be no license attached to this. He apparently just wants to see his name
- * mentioned.
- *
- * This file can be found at http://www.vesa.org/Public/CVT/CVTd6r1.xls
- *
- * Comments and structure corresponds to the comments and structure of the xls.
- * This should ease importing of future changes to the standard (not very
- * likely though).
- *
- * About margins; i'm sure that they are to be the bit between HDisplay and
- * HBlankStart, HBlankEnd and HTotal, VDisplay and VBlankStart, VBlankEnd and 
- * VTotal, where the overscan colour is shown. FB seems to call _all_ blanking
- * outside sync "margin" for some reason. Since we prefer seeing proper
- * blanking instead of the overscan colour, and since the Crtc* values will
- * probably get altered after us, we will disable margins altogether. With
- * these calculations, Margins will plainly expand H/VDisplay, and we don't
- * want that. -- libv
