The Raidsonic devices do not use a 2048k kernel "Kern" partition like the Storlink reference designs. Instead it uses a 3072k partition to fit a slightly larger kernel. Sadly the current OpenWrt Gemini kernel is still bigger than 3072k so we need to make use of the Ramdisk partition as well. Create a special "copy-kernel" version that can deal with the Raidsonic 3072k kernels. Tested on the Raidsonic IB-4220-B booting kernel v6.12.66. Fix a copy/paste error in the image generation makefile while we are at it. Link: https://github.com/openwrt/openwrt/pull/21686 Signed-off-by: Linus Walleij <linusw@kernel.org>
