Until now, Genode referenced a fork of the outdated elfloader-tool
to enable bootstrapping of sel4 on ARM platforms. Because the
elfloader is inherently dependent on the used platforms newer
ARM versions supported by the kernel could not be loaded by the
outdated elfloader. This commit uses a fresh fork of the nowadays
used sel4_tools repository.
Ref #3251
* In base-foc/recipes/src/ replace base-foc with base-foc-pc
* To base-foc/recipes/src add base-foc-arndale, base-foc-pbxa9
* Ensure that the correct base-foc recipe is choosen by the run module
'boot_dir/foc'
* To base-hw/recipes/src add base-hw-arndale, base-hw-imx53_qsb,
base-hw-imx53_qsb_tz, base-hw-odroid_xu, base-hw-panda, base-hw-rpi,
base-hw-wand_quad
* Ensure that the correct base-hw recipe is choosen by the run module
'boot_dir/hw'
This commit changes the semantic of run_boot_dir to link a core
binary with debug symbols only when the designated library is in place.
Follow-up fix refering to issues #2339 and #2700
* introduce new syscall (core-only) to create privileged threads
* take the privilege level of the thread into account
when doing a context switch
* map kernel segment as accessable for privileged code only
Ref #2091
* introduces central memory map for core/kernel
* on 32-bit platforms the kernel/core starts at 0x80000000
* on 64-bit platforms the kernel/core starts at 0xffffffc000000000
* mark kernel/core mappings as global ones (tagged TLB)
* move the exception vector to begin of core's binary,
thereby bootstrap knows from where to map it appropriately
* do not map boot modules into core anymore
* constrain core's virtual heap memory area
* differentiate in between user's and core's main thread's UTCB,
which now resides inside the kernel segment
Ref #2091
relocation is required, to avoid overlapping phdr in the elf binaries, but
sel4 will fail to boot if bender relocates the images at the end of physical
memory. Limit the physical relocation address to a fixed 256M value, so that
sel4 will work.
Issue #2451
