gemini: Add copy-kernel utility package This package just contains a small Gemini-only assembler bootstrap loop to copy the kernel from the two fragments (previously zImage at 0x01600000 and initramdisk at 0x00800000) into one big zImage of up to 8 MB at 0x00400000. It will be built on demand from the Gemini image Makefile. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> 2019-07-17 17:23:31 +00:00			`#`
