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 <n.shubin@yadro.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>

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.

2021-06-24platform: Replace CLINT library usage with ACLINT libraryAnup Patel1-7/+16
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.

2020-05-23lib: utils: Allow CLINT functions to be used for multiple CLINTsAnup Patel1-4/+9
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.
