aspeed: Board init functions and common configs for ast2500 based boardsAdd configuration file with parameters that are very likely to be shared byall ast2500-based boards.Add ast2500-board.c file with the init code that is very likely to beshared by all ast2500-based boards.Reviewed-by: Simon Glass List of files: /rk3399_rockchip-uboot/arch/arm/mach-aspeed/Makefile

14e4b14979574a6b31f4e3037f81d5c66a8ae7b8 - aspeed: Add basic ast2500-specific drivers and configuration

Wed, 18 Jan 2017 21:44:56 +0000

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/arch/arm/mach-aspeed/Makefile

4697abea62a3b02c9c346b94d7eae2e4a1c6cfd0 - aspeed: Add drivers common to all Aspeed SoCs

Wed, 18 Jan 2017 21:44:55 +0000

aspeed: Add drivers common to all Aspeed SoCsAdd support for Watchdog Timer, which is compatible with AST2400 andAST2500 watchdogs. There is no uclass for Watchdog yet, so the driverdoes not follow the driver model. It also uses fixed clock, so no clockdriver is needed.Add support for timer for Aspeed ast2400/ast2500 devices.The driver actually controls several devices, but because all devicesshare the same Control Register, it is somewhat difficult to completelydecouple them. Since only one timer is needed at the moment, this shouldbe OK. The timer uses fixed clock, so does not rely on a clock driver.Add sysreset driver, which uses watchdog timer to do resets and particularwatchdog device to use is hardcoded (0)Reviewed-by: Simon Glass List of files: /rk3399_rockchip-uboot/arch/arm/mach-aspeed/Makefile
