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: 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

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

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

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.

include: sbi_platform: Combine reboot and shutdown into one callback

2020-04-27T09:05:29Z

We can achieve shutdown, cold reboot, and warm reboot using just one sbi_platform callback so we combine system_reboot() and system_shutdown() callbacks into one system_reset() callback. Signed-off-by: Anup Patel Reviewed-by: Atish Patra
