I didn't.

Your mailer is confused.  I bcc the u-boot-release mailing list, and I
presume your mailer (or our mail server) sent you that copy of the mail
instead of the "real" one.

The compiler should convert it into an array lookup automatically, but I
can change it if you insist.  Since I don't like writing code that depends
on the values of an enum, the array will look like this:

	static const enum srds_prtcl srds_table[] = {
		[FM1_DTSEC1] = SGMII_FM1_DTSEC1,
		[FM1_DTSEC2] = SGMII_FM1_DTSEC2,
		[FM1_DTSEC3] = SGMII_FM1_DTSEC3,
		[FM1_DTSEC4] = SGMII_FM1_DTSEC4,
		[FM1_DTSEC5] = SGMII_FM1_DTSEC5,
		[FM1_10GEC1] = XAUI_FM1,
		[FM2_DTSEC1] = SGMII_FM2_DTSEC1,
		[FM2_DTSEC2] = SGMII_FM2_DTSEC2,
		[FM2_DTSEC3] = SGMII_FM2_DTSEC3,
		[FM2_DTSEC4] = SGMII_FM2_DTSEC4,
		[FM2_DTSEC5] = SGMII_FM2_DTSEC5,
		[FM2_10GEC1] = XAUI_FM2,
	};

	if ((port < FM1_DTSEC1) || (port > FM2_10GEC1))
		return NONE;
	else
		return srds_table[port];

I'm not sure that's an improvement.
