SSE instructions

[Simon Glass]

Hi Bin,

U-Boot 64-bit on x86 disables sse, but when enabling Truetype I get a
compiler error:

drivers/video/console_truetype.c: In function 'frac':
drivers/video/console_truetype.c:30:15: error: SSE register return
with SSE disabled
30 | static double frac(double val)

Do you know how to enable SSE for 64-bit?

Regards,
Simon
