xen: Limit execution to EL1 only

2023-04-25T19:31:28Z

Xen core_init() is calling HVC which should be called from EL1 level that's why do Xen initialization only when U-Boot runs in EL1. Signed-off-by: Michal Simek

xen: Fix Kconfig dependencies

2023-04-25T19:31:28Z

XEN config can be enabled by other platforms (even it doesn't need to make sense) that's why fix dependencies. XEN (xenbus.c) requires sscanf (also pvblock needs it). And PVBLOCK is inside drivers/xen folder which requires XEN to be enabled. Signed-off-by: Michal Simek Reviewed-by: Heinrich Schuchardt

Correct SPL uses of XEN_SERIAL

2023-02-10T12:41:41Z

This converts 4 usages of this option to the non-SPL form, since there is no SPL_XEN_SERIAL defined in Kconfig Signed-off-by: Simon Glass

xen: pvblock: Use uclass_probe_all

dm: core: Switch uclass_foreach_dev_probe to use simple iterator

2022-10-18T03:17:12Z

The return value is not used for anythig, and in a later patch the behavior of the _err iterator will change in an incompatible way. Signed-off-by: Michal Suchanek Reviewed-by: Simon Glass Update pvblock_probe() to avoid using internal var: Signed-off-by: Simon Glass

blk: Rename if_type to uclass_id

2022-09-25T14:30:05Z

Use the word 'uclass' instead of 'if_type' to complete the conversion. Signed-off-by: Simon Glass

blk: Switch over to using uclass IDs

2022-09-16T15:05:16Z

We currently have an if_type (interface type) and a uclass id. These are closely related and we don't need to have both. Drop the if_type values and use the uclass ones instead. Maintain the existing, subtle, one-way conversion between UCLASS_USB and UCLASS_MASS_STORAGE for now, and add a comment. Signed-off-by: Simon Glass

blk: Select SPL_LEGACY_BLOCK automatically

2022-09-16T15:05:16Z

Selecting this option can be handled in the Kconfig option itself, as it is with BLK. Update this an drop the various 'select' clauses. Signed-off-by: Simon Glass

blk: Rename HAVE_BLOCK_DEVICE

2022-09-16T15:05:16Z

This option is fact really related to SPL. For U-Boot proper we always use driver model for block devices, so CONFIG_BLK is enabled if block devices are in use. It is only for SPL that we have two cases: - SPL_BLK is enabled, in which case we use driver model and blk-uclass.c - SPL_BLK is not enabled, in which case (if we need block devices) we must use blk_legacy.c Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is different enough from BLK and SPL_BLK that there should be no confusion. Signed-off-by: Simon Glass

drivers: xen: events: fix build issues with disabled Xen HVC

2022-08-04T17:59:59Z

Some setups do not use Xen hypervisor console for logging, e.g. they use emulated PL011 hardware or shared peripherals (real UART). In such cases Xen HVC will be disabled on a build time and will cause issues in current driver implementation. This commit fixes build issues in Xen event channel driver, caused by absense of console event channel, that is not available when console config is disabled. Now console related code will be removed when Xen HVC is turned off. Signed-off-by: Dmytro Firsov Reviewed-by: Anastasiia Lukianenko Reviewed-by: Anastasiia Lukianenko > Signed-off-by: Dmytro Firsov >
