With this patch, the board/<name>/arch property file can have multiple
lines where each line denotes an instruction-set architecture supported
for the board.
Issue #4019Fixes#4034
This patch simplifies the packaging of the base-hw kernel for a given
board, in particular when the board support is hosted as an external
repository such as genode-world. Regardless of where the board-support
is hosted, the content.mk file becomes as simple as:
include $(GENODE_DIR)/repos/base-hw/recipes/src/base-hw_content.inc
The board name is automatically inferred from the path of the src
recipe. The architecture is determined from board/<name>/arch files,
following the pattern of the image_link_address. The attempt to build a
base-hw-<board> binary archive for the wrong architecture is now
gracefully handled by skipping all targets (using the REQUIRES
mechanism).
Besides the improved convenience, the patch results in depot archives
that are much closer tailored to the actual board by omitting files for
architectures that are not used by the board. E.g., the src/base-hw-pc
archive does not contain any ARM-related content.
The patch also restores the package builds for core/bootstrap object
files as a follow-up fix of "base: remove SPEC variables of boards",
which happened to left 'BOARD' undefined in the src archives.
Fixes#4019
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
This patch adds support for booting base-hw kernel on qemu-arm virt
machines. The arm_virt machine has 2GB of RAM, 2 Cortex A15 cores and
uses GICv2 interrupt controller. The arm_64_virt machine also has 2GB of
RAM, but has 4 Cortex A53 cores and uses GICv3. Both machines use PSCI
to boot additional CPU cores.
