History
Xiang W 03f44e6b82 lib: sbi: Optimize saddr mapping in sbi_dbtr.c 
The original implementation mapped saddr individually for each entry.
The updated code now maps saddr for all entries in a single operation.
This change reduces the number of PMP (Physical Memory Protection)
operations, improving efficiency and performance.
