Subject: [U-Boot] [PATCH 3/6 v3] mips: Add LinkIt Smart 7688 support
Date: Thu, 16 Aug 2018 15:27:30 +0200	[thread overview]
Message-ID: <20180816132733.19408-3-sr@denx.de> (raw)
In-Reply-To: <20180816132733.19408-1-sr@denx.de>

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.

v3:
- Removed dtsi file - its added with patch #1
- Improvements to board_debug_uart_init() as suggested by Daniel
- Added comment to board_early_init()
- Removed DEBUG_UART

v2:
- Kconfig entries added with this patch now
