From: Stephen Warren Date: Thu, 12 May 2016 19:32:56 +0000 (-0600) Subject: ARM: tegra: add p2771-0000 board support X-Git-Tag: v2016.07-rc1~27^2 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=10a03382f0f8e774e58df7143e1a8ea52903ae1f;p=oweals%2Fu-boot.git ARM: tegra: add p2771-0000 board support P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion headers. Currently, due to U-Boot's level of support for Tegra186, the only features supported by U-Boot are the console UART and the on-board eMMC. Additional features will be added over time. U-Boot has so far been tested by replacing the kernel image on the device with a U-Boot binary. It is anticipated that U-Boot will eventually replace the CCPLEX bootloader binary, as on previous chips. This hasn't yet been tested.
