Makefile: Add initial kconfig support for each platform

2022-08-08T04:03:09Z

We extend the top-level makefile to allow kconfig based configuration for each platform where each platform has it's own set of configs with "defconfig" being the default config. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: utils/serial: support 'reg-offset' property

2022-04-17T08:27:48Z

reg-offset property is used for offset to apply to the mapbase from the start of the registers in 8250 UART. In Linux kernel, it has been handled in 8250 UART driver. dt-bindings: /Documentation/devicetree/bindings/serial/8250.yaml Signed-off-by: Zong Li Reviewed-by: Anup Patel

lib: sbi: Add timer frequency to struct sbi_timer_device

2021-09-26T14:22:10Z

Generic mdelay() and udelay() functions can be provided by the sbi_timer framework if timer frequency is available in the timer instance provided by the platform support or timer driver. This patch adds timer frequency (timer_freq) member in the struct sbi_timer_device for above purpose. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W

lib: utils/timer: Allow separate base addresses for MTIME and MTIMECMP

2021-08-14T03:32:33Z

We extend the ACLINT library to support separate base addresses for MTIME and MTIMECMP registers. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

platform: Replace CLINT library usage with ACLINT library

2021-06-24T04:09:55Z

The ACLINT devices are backward compatible with SiFive CLINT so we replace all CLINT library usage in various platforms with ACLINT library. As a result of this replacement, the CLINT library is not used by any part of OpenSBI hence we remove it. Signed-off-by: Anup Patel Reviewed-by: Bin Meng Reviewed-by: Xiang W
