From 469d64539007584241ccd475e81038ea4166f17b Mon Sep 17 00:00:00 2001 From: Cástor Muñoz Date: Thu, 4 Feb 2016 20:12:02 +0100 Subject: iPod Classic: prepare i2c and PMU for bootloader When the bootloader starts only IRAM is available, the first task is to ask the PMU to verify if the iPod has previously been hibernated by OF. Due to memory limitations, the kernel cannot be used on this stage. This patch modifies I2C and PMU low level functions to not to depend on kernel (removes mutexes, and uses HW timer instead of current_tick), actual kernel functions are modified to be 'mutexed' wrappers of the new functions.
