openwrt/target/linux/bcm27xx/patches-6.6/950-0990-dts-bcm2712-Add-blpubkey-nvram-node.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0990/1085] dts: bcm2712: Add blpubkey nvram node
The RPi5 firmware also supports exporting the customer
public key stored in flash via device-tree. Define the
node so that the firmware can populate it.
