2020-12-01lib: sbi: Improve system reset platform operationsAnup Patel
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.

2020-05-23lib: utils: Allow CLINT functions to be used for multiple CLINTsAnup Patel
We extend CLINT cold init function to have a "struct clint_data *" parameter pointing to CLINT details. This allows platforms to use CLINT functions for multiple CLINT instances. When multiple CLINTs are present, the platform can also provide one of the CLINT as reference CLINT for other CLINTs. This will help CLINTs to sync their time value with reference CLINT using a time_delta computed in warm init function.

2020-05-01lib: utils: Remove redundant clint_ipi_sync() declarationAnup Patel
The clint_ipi_sync() was removed long time back hence we remove redundant declaration from clint.h Signed-off-by: Anup Patel <[email protected]> Reviewed-by: Alistair Francis <[email protected]> Reviewed-by: Atish Patra <[email protected]>
2020-04-27lib: utils: Add SiFive test deviceAnup Patel
This patch factor-out SiFive test device related stuff into it's own source file from qemu/virt platform. In future, we can find SiFive test device address from device tree as well. Signed-off-by: Anup Patel <[email protected]> Reviewed-by: Atish Patra <[email protected]>
2020-04-27include: sbi_platform: Combine reboot and shutdown into one callbackAnup Patel
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 <[email protected]> Reviewed-by: Atish Patra <[email protected]>

2020-01-02lib: utils: Support CLINT with 32bit MMIO access on RV64 systemAnup Patel
It is possible to have a CLINT implementation which supports only 32bit MMIO accesses on RV64 system so this patch extends our CLINT driver such that platform code can specify whether CLINT supports 64bit MMIO access.

2019-06-19platform: Move platform common to lib/utils.Atish Patra
Currently, platform/common contains platform/non-platform specific common minimal drivers and libraries. This is helpful is all platforms are built within opensbi framework. Move them to lib/utils so that any external platform code also can reuse the minimalistic drivers or other common libraries. This patch doesn't introduce any functional changes.
