rtl838x: add new architecture
This adds support for the RTL838x Architecture.
SoCs of this type are used in managed and un-managed Switches and Routers
with 8-28 ports. Drivers are provided for SoC initialization, GPIOs, Flash,
Ethernet including a DSA switch driver and internal and external PHYs used
with these switches.
Supported SoCs:
RTL8380M
RTL8381M
RTL8382M
The kernel will also boot on the following RTL839x SoCs, however driver
support apart from spi-nor is missing:
RTL8390
RTL8391
RTL8393
The following PHYs are supported:
RTL8214FC (Quad QSGMII multiplexing GMAC and SFP port)
RTL8218B internal: internal PHY of the RTL838x chips
RTL8318b external (QSGMII 8-port GMAC phy)
RTL8382M SerDes for 2 SFP ports
Initialization sequences for the PHYs are provided in the form of
firmware files.
Flash driver supports 3 / 4 byte access
DSA switch driver supports VLANs, port isolation, STP and port mirroring.
The ALLNET ALL-SG8208M is supported as Proof of Concept:
RTL8382M SoC
1 MIPS 4KEc core @ 500MHz
8 Internal PHYs (RTL8218B)
128MB DRAM (Nanya NT5TU128MB)
16MB NOR Flash (MXIC 25L128)
8 GBEthernet ports with one green status LED each (SoC controlled)
1 Power LED (not configurable)
1 SYS LED (configurable)
1 On-Off switch (not configurable)
1 Reset button at the right behind right air-vent (not configurable)
1 Reset button on front panel (configurable)
12V 1A barrel connector
1 serial header with populated standard pin connector and with markings
GND TX RX Vcc(3.3V), connection properties: 115200 8N1
To install, upload the sysupgrade image to the OEM webpage.
