[RFC 0/4] MIPS: barebox as a first stage loader on the Black Swift board

[Antony Pavlov]

This patchseries add necessary low level initialization routines for AR9331 SoC.
The patchseries makes possible to use barebox as a first stage loader
on the Black Swift board.

The patchseries is heavily based on Oleksij Rempel's work on barebox for TP-Link MR3020.

TODOs:

  * add UART initialization routune for DEBUG_LL and NMON;
  * add macros for GPIO_FUNCTION_1 register initialization;
  * check macros names linux kernel source compartibility;
  * DT compatible string vendor "smartlx" appears un-documented.
     The site http://www.smartlx.ru/ is suspended.
