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.

drivers: xen: unmap Enlighten page before jumping to Linux

2022-07-25T18:57:27Z

This commit fixes issue with usage of Xen hypervisor shared info page. Previously U-boot did not unmap it at the end of OS boot process. Xen did not prevent guest from this. So, it worked, but caused wierd issues - one memory page, that was returned by memalign in U-boot for Enlighten mapping was not unmaped by Xen (shared_info values was not removed from there) and returned to allocator. During the Linux boot, it uses shared_info page as regular RAM page, which leads to hypervisor shared info corruption. So, to fix this issue, as discussed on the xen-devel mailing list, the code should: 1) Unmap the page 2) Populate the area with memory using XENMEM_populate_physmap This patch adds page unmapping via XENMEM_remove_from_physmap, fills hole in address space where page was mapped via XENMEM_populate_physmap and return this address to memory allocator for freeing.
