x86: slimbootloader: Set TSC information for tsc_timer

2019-08-09T14:24:02Z

Slim Bootloader already calibrated TSC and provides it to U-Boot. Therefore, U-Boot does not have to re-calibrate TSC. Configuring tsc_base and clock_rate makes x86 tsc_timer driver bypass TSC calibration and use the provided TSC frequency. - Get TSC frequency from performance info hob - Set tsc_base and clock_rate for tsc_timer driver Signed-off-by: Aiden Park Reviewed-by: Bin Meng Tested-by: Bin Meng

x86: Add new slimbootloader CPU type

2019-08-09T14:24:02Z

This slimbootloader CPU type is to enable U-Boot as a payload which runs on top of Slim Bootloader (https://github.com/slimbootloader). The Slim Bootloader is designed with multi-stage architecture for the execution from reset vector to OS booting, and supports QEMU, Apollolake, Whiskeylake and Coffeelake platforms consuming Intel FSP (https://github.com/IntelFsp) for silicon initialization including CAR and memory initialization. The Slim Bootloader generates new HOB (Hand Off Block) which are serial port info, memory map info, performance data info and so on, and passes it to a Payload. U-Boot as a payload will use these HOB information for basic initialization such as serial console. As an initial commit, - Add CONFIG_SYS_SLIMBOOTLOADER to enable slimbootloader CPU type - Add new arch/x86/cpu/slimbootloader directory with minimum codes - Get hob_list pointer from Slim Bootloader Signed-off-by: Aiden Park Reviewed-by: Bin Meng Reviewed-by: Andy Shevchenko Tested-by: Bin Meng
