Add some initial board support for the AR934x and the Qualcomm Atheros DB120 development board. The AR934x SoCs are a MIPS74k based system with increased RAM addressing space, some scratch-pad RAM, an improved gige switch PHY and 2x2 or 3x3 on-board dual-band wifi. This support isn't complete by any stretch; it's just enough to bring the board up for others to tinker with. Notably, the MIPS74k support is broken. However it boots enough to echo some basic probe/attach messages, before dying somewhere in the TLB code. Thankyou to Qualcomm Atheros for their continued support of me doing open source work with their hardware. Tested: * AR9344, mips74k
2013-07-21 04:00:48 +00:00
# $FreeBSD$
# This is a placeholder until the hardware support is complete.
Now that all of the on-chip switch and basic platform support is updated, we can now add all the hardware bits for the DB120. * arge0/argemdio0 is hooked up to an AR8327 switch - which there's currently no support for. However, the bootloader on this board does set it up as a basic switch so we can at least _use_ it ourselves. So we should at least configure the arge0 side of things, including the GMAC register. * .. the GMAC config peels off arge0 from the internal switch and exposes it as an RGMII to said AR8327. * arge1/argemdio1 are hooked up to an internal 10/100 switch. So, that also needs configuring. * Add support for the NOR flash layout. * Add support for the wifi (which works, with bugs, but it works.) What's missing! * No GPIO stuff yet! * No sound (I2S) and no NAND flash support yet, sorry! * The normal DB120 has an external AR95xx wifi chip on PCIe but with the actual calibration data in the NOR flash. My DB120 has been modified to let me use the PCIe slot as a normal PCIe slot. I'll add the "default" settings later when I have access to a non-modified one. * Other stuff, like why the wifi unit gets upset and spits out stuck beacons and interrupt storms everywhere. Sigh. Tested: * DB120 board - AR9344 (mips74k SoC) booting off of SPI flash into multi-user mode.

Add the AR8327 bits to the DB120 config file. There's plenty of hints that I haven't yet fleshed out and are hardcoded in arswitch_8327.c. They're listed here (from OpenWRT) for completeness. This is enough to get the thing up, running and pinging. Note that the mdiobus for the on-switch switch changes - the AR8327 probes first, which exposes mdio1, and thus the arge1 mdiobus will probe and attach as mdio2. That is what the AR9344 on-chip switch has to attach to. Tested: * Qualcomm Atheros DB120

Enable use of the PCIe connected wifi on the DB120 (AR9344) board. The on-board NIC is an 3x3 AR9380 with 5GHz only. * enable pci code in AR9344_BASE * enable ath_pci and the firmware loading bits in DB120 * add in the relevant hints in DB120.hints to inform the probe/attach code where the PCIe fixup data is for the onboard chip. This is only relevant for a default development board.
