| * rsa: let rsa_of_read_key() return a fully allocated keySascha Hauer2019-10-151-4/+6
| | | | | | | | | | | | | | | | | | | | Until now rsa_of_read_key() took a pointer to a key and filled the struct rsa_public_key members with allocated values. So far we have never freed these values. Change rsa_of_read_key() to always return a fully allocated key and provide rsa_key_free() to free it. Let the FIT image code free the key after usage.

| * command: Use array of pointers to commandsSascha Hauer2019-10-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to store the commands as a linker array. One problem with this is that on X86_64 for unknown reasons the linker uses a different struct alignment than the compiler, so when we use the linker to compose the array and the compiler to iterate over it we have to play tricks with manually adjusting the alignment. The other problem is that we declare the commands as const (and also put it in .rodata), but in fact we do not treat it as const: we put the commands onto a list which modifies the struct list_head list member of struct command. With this patch we no longer put the command themselves into an array, but instead create an array of pointers to the commands. This inherently solves the second issue as well.

When the root file system is read-only systemd cannot persist the machine id. In case multiple redundant slots are used the machine id will vary. When not handled explicitly the machine id will also change during system updates. It is possible to pass a machine id to the kernel which will be used by systemd (systemd.machine_id=). If global.bootm.provide_machine_id (or nv.bootm.provide_machine_id) is true then provide the machine id from global.machine_id as systemd.machine_id= parameter to the Kernel. Note that global.machine_id must be set, either by the machine_id_set_bootarg late init call or by setting it manually with nv.machine_id if necessary.

It is then available as global.machine_id. It can be overwritten with nv.machine_id if necessary. Passing the machine id to the kernel is done in a separate patch. Note: if multiple sources provide hashable device-specific information (via machine_id_set_hashable()) the information provided by the last call prior to the late initcall set_machine_id() is used to generate the machine id from. Thus when updating barebox the machine id might change. Signed-off-by: Bastian Krause <bst@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Fix this, by restricting the menu to the non-multi-image configurations, i.e. CONFIG_ARCH_* symbols become specific to non-multi-image. The multi-image configurations on the other hand directly select the CONFIG_SOC_* symbol they require. Existing CONFIG_ARCH_* usage is adjusted to align with the new usage. Eventually, we would want to have a at91_multi_defconfig along with this, but for now leave existing configs as is.
