Dear coreboot,
I am trying to finish the port for the Asus F2A85-M Pro (variant of Asus
F2A85-M). After getting the serial console working [1], it can be seen,
that accessing `DMA1_RESET_REG` in `isa_dma_init()` hangs the system [2].
outb(0, DMA1_RESET_REG);
Commenting this out, coreboot runs through and loads the payload.
SeaBIOS has similar code, also hanging the system.
// first reset the DMA controllers
outb(0, PORT_DMA1_MASTER_CLEAR);
I am at a loss. If you have an idea, how to fix it, I am all ears.
Kind regards,
Paul
