From 95def3cf5d24aebbcdffe6c4fc1a39288cf00b6a Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Mon, 25 Jul 2016 16:26:45 +0530 Subject: [PATCH] i2c: i2c-uclass-compat: avoid any BSS usage As I2C can be used before DRAM initialization for reading EEPROM, avoid using static variables stored in BSS, since BSS is in DRAM, which may not have been initialised yet. Explicitly mark "static global" variables as belonging to the .data section.
