Cover letter [PATCH 0/5] ARM: Broadcom Brahma-B15 readahead cache support
Quoted 7 lines · Florian Fainelli

Hi all,

This patch series adds support for the Broadcom Brahma-B15 CPU read-ahead cache which is to be found in several Broadcom SoCs, and mainline brcmstb.

Let me know your thoughts on this, we have tried to minimize both the compile-time and runtime impact for non-Broadcom CPU parts.

Any feedback on this implementation? Thanks!
