Already in linux-firmware/oracular since version
20240730.git65c5d9b1-0ubuntu1.
** Description changed:
+ [SRU Justification]
+
+ [Impact]
+
+ Starting from Intel Lunar Lake, the ISH firmware will reside in system
+ root as separated blobs, and the kernel driver is responsible for
+ loading a preferred one based on DMI info.
+
+ [Fix]
+
+ Kernel fixes in linux-next:
+ * aa4674c525e1e hid: intel-ish-hid: Add support for vendor customized
firmware loading
+ * 641361538b68d HID: intel-ish-hid: Use CPU generation string in driver_data
+ * 87de1615194ee Documentation: hid: intel-ish-hid: Add vendor custom firmware
loading
+
+ linux-firmware in upstream tag 20240709:
+ * 33a8b2a7f604 linux-firmware: Add ISH firmware file for Intel Lunar Lake
platform
+
+ [Test Case]
+
+ dmesg dumps:
+ ```
+ intel_ish_ipc 0000:00:12.0: ISH loader: firmware loaded. size:748032

+
+ [Where problems could occur]
+
+ This is to include generic blob provided by Intel for all Lunar Lake
+ platforms. It may not be stable, may not be functional, and may have
+ various problems until the hardware vendor submit their own.
