The i12 tvbox is an A20 based android tvbox, with 1G RAM, 4G nand flash,ap6210 sdio wifi + bt (broadcom BCM43362 sdio wifi + uart attached brcm bt),2USB host ports using USB-A receptacles and a micro-usb receptacle for USB OTG,and 100Mbit ethernet.The PCB is labelled i12-a20 hence I've named the board i12-a20. It is usedin noname allwinner A20 tv-boxes, which are sometimes sold with Q5 orQT840A as product name.Note this patch does NOT enable the ethernet port, as the phy-power iscontroller through a gpio-pin (PH21) and we don't have support for havinga gpio power pin for the phy (yet) in the GMAC driver (nor in the EMAC one).Signed-off-by: Hans de Goede. Struct dwethdev contains fields which are accessed via DMA, so make sure itis aligned to a dma boundary.

NALIGNThis is required at least on ARM.When sending instead of simply invalidating the entire descriptor, flushas little as possible while still respecting ARCHDMAMINALIGN, asrequested by Alexey.Signed-off-by: Ian Campbell Cc: Alexey Brodkin Signed-off-by: Hans de Goede -v2: - collapsed 'net/designware: align cache invalidation on rx' and'net/designware: invalidate entire descriptor in dwethsend' intoone.- roundup sizeof(txrxstatus) to ARCHDMAMINALIGN instead of justinvalidating the entire descriptor. The DMA code in sunximmc.c is broken. Mmctransdatabydma allocates thedma descriptors on the stack, and then exits while the dma transfer is inprogress, so the dma engine is reading stack memory which at that point maybe re-used. So far we've gotten away with this by luck, but recent u-bootchanges have shifted the stack start address by 16 bytes, which combinedwith dma alignment now exposes this problem.Since we end up just busy waiting for the dma engine anyway, this commitfixes things by simply removing the dma code, resulting in smaller bug-freecode.Signed-off-by: Hans de Goede.
Similar to the USB NIC found on OMAP5uEVM, PandaBoard and BeagleBoard-XMboards, the sunxi SoCs have a NIC onboard without an embedded MAC address.Just like the omap used on these boards, the sunxi SoCs do have a unique chipid, in the form of the 128 bit SID register:So mimick the BeagleBoard-XM board code (commit ) and use the chip idto generate a unique fixed MAC address.We check for the SID not being all 0, since some early A20 batchesshipped without having there SID programmed.Note we use specific parts of the 128 bits, since some parts indicate theSoC family / revision, and thus are fixed. The algorithm for this was takenfrom the linux-sunxi.org kernels.Signed-off-by: Jonathan Liu [email protected]: Expanded the commit message with some more infoSigned-off-by: Hans de Goede.
This is a 7' tablet with Allwinner A20 SoC. More details atDRAM settings are the same as in the pre-installed Android firmware.Reliability has been verified by using the lima-memtester tool in twoconfigurations:1.
The default 'dramclock=384MHz, dcdc3=1.250V' settings2. Artificially adjusted 'dramclock=408MHz, dcdc3=1.225V' settings(DRAM clock frequency increased by one step and dcdc3 voltagereduced by one step).No problems have been detected in either of them after several hoursof running tests.Signed-off-by: Siarhei Siamashka.
