Belkin RT-3200 / Linksys E8450
|
||||
******************************
|
||||
|
||||
This device is based on a 64 bit Mediatek MT7622 ARM platform,
|
||||
and is "work in progress" in Liminix.
|
||||
|
||||
The factory flash image contains ECC errors that make it incompatible
|
||||
with Liminix: you need to use the `OpenWrt UBI Installer <https://github.com/dangowrt/owrt-ubi-installer>`_ to rewrite the partition layout before
|
||||
you can flash Liminix onto it (or even use it with "tftpboot",
|
||||
if you want the wireless to work).
|
||||
|
||||

||||

|
||||
- b/g/n wireless using MediaTek MT7622BV (MT7615E driver)

Subject: [PATCH] phram: Use memremap() to allow mapping of system RAM
|
||||
|
||||
Using memremap() instead of ioremap() allows mapping a disk image in
|
||||
system RAM that has somehow been reserved. It should fall back
|
||||
to ioremap() where necessary.
|
||||
|
||||
Entirely untested, and I'm not convinced this is a good idea at all.
