This series will add support for MediaTek MT7621 SoC with two reference boards and related drivers.
The MediaTek MT7621 is a network processor integrating a dual-core dual-threaded MIPS 1004Kc processor running at a normal frequency of 880MHz. This chip can be found in many wireless routers.
This series add all basic drivers which are useful in u-boot, like usb, sdxc, ethernet, spi, nand and serial.
Currently this patch series only supports building the ram-bootable image as it needs the preloader from MediaTek SDK.
Thanks, Weijie
v4 changes: - Add full support for booting from flash
v3 changes: - Rewrite clk driver to follow definitions from upstream kernel - Implement noncached_alloc() for MIPS platform - Update register remap for mtk-eth driver needed by mt7621
v2 changes: - Add a kconfig for max supported ram size - Remove network configs from default config file - Add config file for mt7621-rfb boards
