I know that Jon Nettleton from SolidRun achieved some results with PWM controller support in UEFI recently, but I don't know when he's going to share those changes. Btw, he's also mentioned that FreeBSD should support I2C controller (in order to read temperature) known in ACPI as NXP0001. It seems to me that sys/arm/freescale/imx/imx_i2c.c should work, but it expects I2C controller to be described in FDT. If you could modify it to attach imx_i2c driver to the I2C controller on ACPI bus, it might be useful. Regards, Dmitry
