+
+Upstream GCC uses a libgcc function for saving/restoring registers. This
+makes the code bigger, and upstream kernels need to carry that function
+for every single kernel module. Our GCC is patched to avoid those
+references, so we can drop the extra bloat for modules.

+Subject: misc: owl-loader for delayed Atheros ath9k fixup
+
+Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
+need to be able to initialize the PCIe wifi device. Normally, this is done
+during the early stages of booting linux, because the necessary init code
+is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
+However,this isn't possible for devices which have the init code for the
+Atheros chip stored on NAND in an UBI volume. Hence, this module can be
+used to initialze the chip when the user-space is ready to extract the
+init code.
