2020-07-30riscv: Allow building with kcov coverageTobias Klauser
Add ARCH_HAS_KCOV and HAVE_GCC_PLUGINS to the riscv Kconfig. Also disable instrumentation of some early boot code and vdso. Boot-tested on QEMU's riscv64 virt machine.

2019-12-08riscv: Fix build dependency for loaderOlof Johansson
The Makefile addition for the flat image loader missed an obj prefix. For most parallel builds this worked out fine, but with -j1 the dependency wasn't fulfilled and thus fails: arch/riscv/boot/loader.S: Assembler messages: arch/riscv/boot/loader.S:7: Error: file not found: arch/riscv/boot/Image Fixes: 405fe7aa0dba ("riscv: provide a flat image loader") Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Olof Johansson <olof@lixom.net> Reviewed-by: Anup Patel <anup@brainfault.org> Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>

2019-11-17riscv: provide a flat image loaderChristoph Hellwig
This allows just loading the kernel at a pre-set address without qemu going bonkers trying to map the ELF file. Contains a contribution from Aurabindo Jayamohanan to reuse the PAGE_OFFSET definition.

2019-11-12RISC-V: Add multiple compression image format.Atish Patra
Currently, there is only support for .gz compression type for generating kernel Image. Add support for other compression methods(lzma, lz4, lzo, bzip2) that helps in generating a even smaller kernel image. Image.gz will still be the default compressed image.

2018-11-20RISC-V: Build flat and compressed kernel imagesAnup Patel
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.
