Avoid use of REP_DIR in *.mk files to simplify the use of these files as
templates for a board hosted in a separate repository.
Use REP_INC_DIR for searching headers, thereby considering headers
hosted in an external repository.
Issue #3168
* 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
To access the ARM Trusted Firmware from the platform driver
fill the new `managing_system` call of the PD session with life resp.
do a SMC call on behalf of the client.
Fix#3816
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.
Fixes#3673
