aspeed: Add basic ast2500-specific drivers and configurationClock DriverThis driver is ast2500-specific and is not compatible with earlierversions of this chip. The differences are not that big, but they arein somewhat random places, so making it compatible with ast2400 is notworth the effort at the moment.SDRAM MC driverThe driver is very ast2500-specific and is completely incompatiblewith previous versions of the chip.The memory controller is very poorly documented by Aspeed in thedatasheet, with any mention of the whole range of registers missing. Theinitialization procedure has been basically taken from Aspeed SDK, whereit is implemented in assembly. Here it is rewritten in C, with very limitedunderstanding of what exactly it is doing.Reviewed-by: Simon Glass List of files: /rk3399_rockchip-uboot/drivers/clk/aspeed/Makefile
