u-boot.git/drivers/serial/serial_arc.c, branch v2017.09 Unnamed repository; edit this file 'description' to name the repository. dm: Rename dev_addr..() functions 2017-06-01T13:03:01+00:00 Simon Glass sjg@chromium.org 2017-05-17T23:18:05+00:00 a821c4af79e4f5ce9b629b20473863397bbe9b10 These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

dm: core: Replace of_offset with accessor 2017-02-08T13:12:14+00:00 Simon Glass sjg@chromium.org 2017-01-17T23:52:55+00:00 e160f7d430f163bc42757aff3bf2bcac0a459f02 At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

And right afetr relocation we zero .bss - effectively cleaing register address set for early console.
