Hi, l4 hackers :-)
I'm trying to secure Ethernet on L4 linux using Freescale imx6q.
Referencing other 'imx28.io' file which succeeded in securing Ethernet ,
I'm modifying my 'imx6q.io' file as follows..
NIC => new Deviceo()
.hi-d = "imx6q-fec";
new-res Mmio (0x02188000 .. 0x0218BFFF);
new-res Irq (150);
new-res Irq (151);
DMAMEM => new Deivce()
new-res Mmio_ram (0x80000, 0);
141x => new System_bus()
"imx6q-fec" -> wrap(hw-root.NIC);
"dmamem" => wrap(hw-root, DMAMEM);
What mean 'DMAMEM' ?
And What is the function of which name is 'Mmio_ram()' ?
I know that 'Mmio()' need arguments which are start and end address.
But, I don't know 'Mmio_ram()'.
Please, help me.
If you tell a bit me hints, I'd appreciate it.
