lib: utils/reset: Remove SiFive Test reset driver

2023-07-31T08:39:24Z

The functionality of SiFive Test reset driver is easily available through Syscon reset driver so let us remove the SiFive Test driver. Signed-off-by: Anup Patel

lib: utils: atcsmu: Add Andes System Management Unit support

2023-01-22T12:02:50Z

This patch adds atcsmu support for Andes AE350 platforms. The SMU provides system management capabilities, including clock, reset and power control based on power domain partitions. Signed-off-by: Yu Chien Peter Lin Reviewed-by: Anup Patel

lib: utils/sys: Allow custom HTIF base address for RV32

2023-01-06T12:31:36Z

commit 6dde43584f18 ("lib: utils/sys: Extend HTIF library to allow custom base address") forgot to update do_tohost_fromhost() codes for RV32, which still accesses the HTIF registers using the ELF symbol address directly.

lib: utils/sys: Use kconfig for enabling/disabling drivers

2022-08-08T04:03:31Z

We update system drivers makefile to use kconfig for enabling/disabling drivers. To avoid compile errors, we also enable appropriate system drivers for each platform. Signed-off-by: Anup Patel Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

lib: utils/sys: Extend HTIF library to allow custom base address

2022-01-11T12:47:49Z

Some of RISC-V emulators provide HTIF at fixed base address so for such emulators users have to hard-code HTIF base address in the linker script. To address this problem, we let users optionally provide fixed HTIF base address via platform support (or device tree). Signed-off-by: Anup Patel Reviewed-by: Dong Du Reviewed-by: Atish Patra

lib: sbi: convert reset to list

2021-10-11T04:29:29Z

To support different handlers for different types of resets, we are adding a sbi_list of restart handlers. Instead of sbi_system_reset_set_device we use sbi_system_reset_add_device to reflect the actual meaning. Signed-off-by: Nikita Shubin Reviewed-by: Anup Patel

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

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
