From 70f22b667a7d91c68d663c1bf9ef1c0bdcbdd377 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Thu, 21 Jun 2012 15:45:38 -0400 Subject: I2C: Move F1-only errata workarounds out of libmaple/i2c.c. The IRQ priority hack is unnecessary on targets with properly functioning I2C IRQ handlers, so we shouldn't use it unless we have to. Add a mechanism so a series header can provide such a hack if necessary. Have the F1 series header use this mechanism.
