The Echo R1 is a new open-hardware music player design, based on the STM32H743 microcontroller. Schematics and hardware documentation for it can be found here: - https://github.com/amachronic/echoplayer This is an incomplete port. The bootloader can be loaded using OpenOCD and it can draw to the LCD using SPI. SDRAM is working but hasn't been extensively tested. Change-Id: Ifd2bee15c49868fbc989683d3ca14dce48bf3e18
