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

lib: sbi: Simplify system reset platform operations

2021-04-28T11:55:00Z

Instead of having system_reset_check() and system_reset() callbacks in platform operations, it will be much simpler for reset driver to directly register these operations as a device to the sbi_system implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: sbi: Simplify ipi platform operations

2021-04-28T11:33:31Z

Instead of having ipi_send() and ipi_clear() callbacks in platform operations, it will be much simpler for ipi driver to directly register these operations as a device to sbi_ipi implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: sbi: Simplify timer platform operations

2021-04-28T11:30:49Z

Instead of having timer_value(), timer_event_start(), and timer_event_stop() callbacks in platform operations, it will be much simpler for timer driver to directly register these operations as device to the sbi_timer implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis

lib: sbi: Simplify console platform operations

Instead of having console_putc() and console_getc() callbacks in platform operations, it will be much simpler for console driver to directly register these operations as device to the sbi_console implementation. Signed-off-by: Anup Patel Reviewed-by: Alistair Francis Reviewed-by: Xiang W

platform: template: Fix compile error

2021-01-18T09:19:56Z

This clint driver init functions were incorrectly used in template platform which resulted in compile error. This patch fixes clint driver function usage in template platform. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: sbi: Improve system reset platform operations

2020-12-01T11:40:31Z

To implement the SBI SRST extension, we need two platform operations for system reset: 1) system_reset_check() - This operation will check whether given reset type and reason are supported by the platform 2) system_reset() - This operation will do the actual platform system reset and it will not return if reset type and reason are supported by the platform This patch updates system reset related code everywhere as-per above.

firmware: Remove FW_PAYLOAD_FDT_PATH compile-time option

2020-10-18T04:59:59Z

The FW_PAYLOAD_FDT_PATH compile-time option is replaced by FW_FDT_PATH compile-time option which is more flexible and common across all OpenSBI firmwares. This patch removes FW_PAYLOAD_FDT_PATH and updates related documentation to use FW_FDT_PATH. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
