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.
