From 803173a19c998a5223a71a6ae60c9dfa60b7fd44 Mon Sep 17 00:00:00 2001 From: Nicholas Chin Date: Thu, 1 Dec 2022 11:51:04 -0700 Subject: flashrom.8.tmpl: Clarify supported ft2232_spi frequencies The manpage suggests that ft2232_spi chips are only capable of up to 6 MHz SPI clock frequencies, whereas flashrom disables the divide-by-5 prescaler on the 'H' chips allowing up to 30 MHz frequencies. This detail was already present in the comments of ft2232_spi.c.
