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..
=================== hw-root { NIC => new Deviceo() { .hi-d = "imx6q-fec"; new-res Mmio (0x02188000 .. 0x0218BFFF); new-res Irq (150); new-res Irq (151); }
DMAMEM => new Deivce() { .hid ="dmamem"; 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.
