OK
bool "Support CACHE drivers"helpEnable CACHE drivers in SPL. These drivers can store data so thatfuture requests for that data can be served faster. Enable this optionThe description here "store data so that ..." does not apply to cache drivers
Do you have any suggestions about how to describe it more precisely ?
The descriptions says drivers can store data, but cache driver does not store data at all. I think you enabled it just for boot time performance?
Yes, so the description mention about "served faster", it can represent improve boot time performance widely.
Maybe you think store data is that kind of store data in flash. Cache will store data in it, so CPU can execute more faster.
