yegorslists at googlemail.com
yegorslists at googlemail.com
Thu Oct 6 03:55:08 PDT 2016
From: Yegor Yefremov <yegorslists at googlemail.com>
OnRISC Baltos devices are based on a am335x SoC and can be booted
either from MMC or NAND.
Signed-off-by: Yegor Yefremov <yegorslists at googlemail.com>

Changes:
v3: - make hw_param a local variable
- implement memory size detection
- remove baltos_mem_init initcall
v2: - remove typedef
- rework invalid EEPROM content handling
- add mmc0 as boot device for MMC boot source
