nvme: Enable PCI bus mastering

2023-05-11T02:25:29Z

U-Boot sets up devices ready for use, but coreboot does not. Enable this so that NVMe works OK from coreboot. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

bootstd: Add a new pre-scan priority for bootdevs

2023-01-23T23:11:41Z

We need extensions to be set up before we start trying to boot any of the bootdevs. Add a new priority before all the others for tht sort of thing. Also add a 'none' option, so that the first one is not 0. While we are here, comment enum bootdev_prio_t fully and expand the test for the 'bootdev hunt' command. Signed-off-by: Simon Glass

bootstd: Add an NVMe bootdev

2023-01-23T23:11:40Z

Add a bootdev for NVMe so that these devices can be used with standard boot. 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

blk: Enable CONFIG_BLK for all media

2022-09-16T15:05:00Z

Enable this option on all boards which support block devices. Drop the related depencies on BLK since these are not needed anymore. Disable BLOCK_CACHE on M5253DEMO as this causes a build error. Signed-off-by: Simon Glass

nvme: Fix multipage prp-list

2022-09-15T13:55:30Z

The nvme driver falsely assumed that the last entry on a page of the prp-list always points to the next page of the prp-list. This potentially can lead to the illegal creation of pages on the prp-list with only a single entry. This change now ensures that splitting the prp-list into multiple pages, behaves now as required by the NVME-Spec. Related to this, also the size of the memory allocation is adjusted accordingly.

nvme: Do a clean NVMe shutdown

2022-08-26T19:00:05Z

The brute-force controller disable method can end up racing controller initialization and causing a crash when we shut down Apple ANS2 NVMe controllers. Do a proper controlled shutdown, which does block until things are quiesced properly. This is nicer in general for all controllers.
