From 2189d5f1e8a2fd74ce52906999fd50c8f8330c81 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 14 Nov 2019 12:57:20 -0700 Subject: Move strtomhz() to vsprintf.h At present this function sits in its own file but it does not really justify it. There are similar string functions in vsprintf.h, so move it there. Also add the missing function comment. Use the vsprintf.h include file explicitly where needed.
