riscv: Fix build dependency for loader

2019-12-09T04:19:30+00:00

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

riscv: provide a flat image loader

2019-11-17T23:17:39+00:00

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.

RISC-V: Add multiple compression image format.

2019-11-12T20:04:52+00:00

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.

riscv: dts: HiFive Unleashed: add default chosen/stdout-path

2019-10-14T19:30:30+00:00

Add a default "stdout-path" to the kernel DTS file, as is present in many
of the board DTS files elsewhere in the kernel tree. With this line
present, earlyconsole can be enabled by simply passing "earlycon" on the
kernel command line.  No specific device details are necessary, since the
kernel will use the stdout-path as the default.
