This patchseries adds full clock and RAM initialization for AR9331-based boards: now barebox can start without any other bootloader's help. This series tested with TP-Link MR3020 (DDR1 RAM) and Black Swift (DDR2 RAM) boards. See also https://github.com/pepe2k/u-boot_mod Future works: * add 'check run from ROM' commit by Oleksij Rempel (do 0xbfc test); * enable more GPIO features (see 'pbl_reg_set (1 << 18), 0xb80600ac'). Changes since v1: * make commit messages more consistent; * add 'Future works' to cover letter.
