Documentation summary for feature / change

This PR enables CONFIG_BCACHE on bcm2711 builds.
CONFIG_BCACHE is enabled on most other boards. There are no reasons it should be enabled on other boards but not Raspberries.

How Has This Been Tested?

I've tested this by compiling the kernel and making sure bcache works on Raspberry Pi 5.

Summary by CodeRabbit

  • New Features
    • Added BCACHE filesystem cache backend as a loadable kernel module. This change makes BCACHE available in both current and edge kernel configurations, allowing it to be loaded dynamically at runtime where supported. Users may see the module available for enabling or loading via standard kernel module management tools.

Walkthrough

Added the kernel configuration symbol CONFIG_BCACHE set to module ("m") in two BCM2711 kernel config files, enabling BCACHE as a loadable kernel module in those defconfigs.

Poem

🐰 I found a config, tidy and neat,
A little module hopping on its feet.
BCACHE tucked in as "m" with cheer,
Ready to cache, springing near! 🥕

Can you check against edge and legacy config too?

Legacy already has this enabled. I've now updated edge config as well.
