2018-12-19mips: mt76xx: Flush d-cache in arch_misc_init() to solve d-cache issuesStefan Roese
It has been noticed, that sometimes the d-cache is not in a "clean-state" when U-Boot is running on MT7688. This was detected when using the ethernet driver (which uses d-cache) and a TFTP command does not complete. Flushing the complete d-cache (again?) here seems to fix this issue.

2018-11-18mips: mt76xx: gardena-smart-gateway: Add board_late_init() to set LED def stateStefan Roese
This is needed to set the LEDs automatically to a default state, as configured in the dts. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
2018-11-18mips: mt76xx: Enable watchdog supportStefan Roese
This patch enables and starts the watchdog on the MT7620 platform. Currently the WD timeout is configured to 60 seconds.

2018-11-18mips: mt76xx: lowlevel_init.S: Add missing memory controller reset in DDR initStefan Roese
This fixes an issue which has been noticed on the Gardena board, with the watchdog enabled, where the watdchdog reset (after a system hang) did result in reporting of 2.9 GiB and a hang after this. With this patch applied the memory controller is correctly reset and initialized again even after a watchdog reset.

2018-09-23mips: Add Gardena Smart-Gateway board supportStefan Roese
The Gardena Smart-Gateway boards have a MT7688 SoC with 128 MiB of RAM and 8 MiB of flash (SPI NOR) and additional 128MiB SPI NAND storage. This patch also includes 2 targets. One is the target that can be programmed into the SPI NOR flash and a 2nd target "xxx-ram" is added to support loading and booting via an already running U-Boot version. This allows easy development and testing without the need to flash the image each time.

2018-09-23mips: Add LinkIt Smart 7688 supportStefan Roese
The LinkIt Smart 7688 modules have a MT7688 SoC with 128 MiB of RAM and 32 MiB of flash (SPI NOR). This patch also includes 2 targets. One is the target that can be programmed into the SPI NOR flash and a 2nd target "xxx-ram" is added to support loading and booting via an already running U-Boot version. This allows easy development and testing without the need to flash the image each time.

2018-09-22mips: Add basic MediaTek MT7620/88 supportStefan Roese
This patch adds basic support for the MediaTek MT7620/88 SoCs. Parts of the code is copied from the MediaTek GitHub repository: https://github.com/MediaTek-Labs/linkit-smart-uboot.git The mt7628a.dtsi file is imported from Linux v4.17. Support for the LinkIt Smart 7688 module and the Gardena Smart Gateway both based on the MT7688 will be added in further patches.
