This patch extends Linux RISC-V build system to build and install: Image - Flat uncompressed kernel image Image.gz - Flat and GZip compressed kernel image Quiet a few bootloaders (such as Uboot, UEFI, etc) are capable of booting flat and compressed kernel images. In case of Uboot, booting Image or Image.gz is achieved using bootm command. The flat and uncompressed kernel image (i.e. Image) is very useful in pre-silicon developent and testing because we can create back-door HEX files for RAM on FPGAs from Image.
