Amlogic aml8726-m3 / aml8726-m6 SoC status

[John Wehle]

Here's quick blurb regarding the current status of support for
Amlogic aml8726-m3 and aml8726-m6 SoC.

In my private source tree I've implemented the following:

Done / lightly tested:

  Basic machdep code

  Interrupt controller

  Timer

  Real time clock

  UART

  GPIO

  SD card

  USB

  Watchdog

  Random number generator

  PLL / Clock frequency measurement

Done / untested:

  I2C (using manual mode)

Work in progress:

  Ethernet (it seems like the hardware is actually a DesignWare Core
            so this driver may be useful for supporting other SoC).

  Frame buffer (needs additional code to program the PLLs ...
                works if the PLLs are setup by the firmware)

Currently FreeBSD successfully boots to the login prompt on an aml8726-m6
board using a SD card and a serial console.

Plans:

  Finish the ethernet driver.

  SMP

  Supply a series of patches so the code can be considered for HEAD.

  Test on a aml8726-m3 board.

  Revisit the frame buffer driver.

  Test on an Ainol Elf-2 tablet.

  Look at supporting flash memory.
