2022-11-07dm: blk: Add probe in blk_first_device/blk_next_deviceMichal Suchanek
The description claims that the device is probed but it isn't. Add the device_probe() call. Also consolidate the iteration into one function. Fixes: 8a5cbc065d ("dm: blk: Use uclass_find_first/next_device() in blk_first/next_device()") Signed-off-by: Michal Suchanek <[email protected]>
2022-11-07dm: sandbox: Switch over to using the new host uclassSimon Glass
Update the sandbox implementation to use UCLASS_HOST and adjust all the pieces to continue to work: - Update the 'host' command to use the new API - Replace various uses of UCLASS_ROOT with UCLASS_HOST - Disable test_eficonfig since it doesn't work (this should have a unit test to allow this to be debugged) - Update the blk test to use the new API - Drop the old header file Unfortunately it does not seem to be possible to split this change up further.

2022-11-07dm: sandbox: Create a block driverSimon Glass
Create a block driver for the new HOST uclass. This handles attaching and detaching host files. For now the uclass is not used but this will be plumbed in with future patches. Signed-off-by: Simon Glass <[email protected]>
2022-11-07dm: sandbox: Create a new HOST uclassSimon Glass
Sandbox supports block devices which can access files on the host machine. At present there is no uclass for this. The devices are attached to the root devic. The block-device type is therefore set to UCLASS_ROOT which is confusing. Block devices should be attached to a 'media' device instead, something which handles access to the actual media and provides the block driver for the block device. Create a new uclass to handle this. It supports two operations, to attach and detach a file on the host machine. For now this is not fully plumbed in. Signed-off-by: Simon Glass <[email protected]>
2022-11-07dm: blk: Tidy up obtaining a block device from its parentSimon Glass
This function now finds its block-device child by looking for a child device of the correct uclass (UCLASS_BLK). It cannot produce a device of any other type, so drop the superfluous check. Provide a version which does not probe the device, since that is often needed when setting up the device's platdata. Also fix up the function's comment. Signed-off-by: Simon Glass <[email protected]>
2022-11-07dm: test: Clear the block cache after running a testSimon Glass
Some tests access data in block devices and so cause the cache to fill up. This results in memory being allocated. Some tests check the malloc usage at the beginning and then again at the end, to ensure there is no memory leak caused by the test. The block cache makes this difficult, since the any test may cause entries to be allocated or even freed, if the cache becomes full. It is simpler to clear the block cache after each test. This ensures that it will not introduce noise in tests which check malloc usage. Add the logic to clear the cache, using the existing blkcache_invalidate() function. Drop the duplicate code at the same time. Signed-off-by: Simon Glass <[email protected]>

2022-10-31dm: blk: mmc: Tidy up some Makefile rules for SPLSimon Glass
Use the correct SPL_TPL_ variable so that these features can be enabled in TPL and VPL as needed. Disable it by default in TPL to avoid any code-size increase. No boards are actually using it since the Makefile rules don't allow including drivers/block/ with TPL_DM enabled. It can be manually enabled as needed.

2022-10-31dm: blk: Add udevice functionsSimon Glass
At present we have functions called blk_dread(), etc., which take a struct blk_desc * to refer to the block device. Add some functions which use udevice instead, since this is more in keeping with how driver model is supposed to work. Update one of the tests to use this. Note that it would be nice to update the functions in disk-uclass.c to use these new functions. However they are not quite the same. For example, disk_blk_read() adds the partition offset to 'start' when calling the cache read/fill functions, but does not with part_blk_read(), which does the addition itself. So as designed the code is duplicated. Signed-off-by: Simon Glass <[email protected]>
2022-10-17dm: blk: Do not use uclass_next_device_errMichal Suchanek
blk_first_device_err/blk_next_device_err uses uclass_first_device_err/uclass_next_device_err for device iteration. Although the function names superficially match the return value from uclass_first_device_err/uclass_next_device_err is never used meaningfully, and uclass_first_device/uclass_next_device works equally well for this purpose. In the following patch the semantic of uclass_first_device_err/uclass_next_device_err will be changed to be based on uclass_first_device_check/uclass_next_device_check breaking this sole user that uses uclass_next_device_err for iteration.

2022-09-16blk: Switch over to using uclass IDsSimon Glass
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 <[email protected]>
2022-09-16blk: Rewrite if_type to name functionsSimon Glass
These are currently using a simple array lookup in one direction, and relying on if_type being sequential. With the move to uclass IDs this needs to change. Update the code to prepare for the new way. This patch is intended to introduce no functional change. The returning of "(none)" from blk_get_if_type_name() is handling a case that should not happen in either case. Signed-off-by: Simon Glass <[email protected]>

2022-09-16blk: Hide the BLK and SPL_LEGACY_BLOCK optionsSimon Glass
We don't want boards to be able to change these. They can be handled as dependencies of options that need them, such as SPL_MMC. There is no point in enabling the block interface without any storage devices to create a block device. Hide both options from the 'menuconfig' display and deny their use in defconfig files.

2022-09-16blk: Rename HAVE_BLOCK_DEVICESimon Glass
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 <[email protected]>

2022-09-16blk: Use a function for whether block devices are availableSimon Glass
At present we use HAVE_BLOCK_DEVICE to indicate when block devices are available. This is a very strange option, since it partially duplicates the BLK option used by driver model. It also covers both U-Boot proper and SPL, even though one might have block devices and another not. As a first step towards correcting this, create a new inline function called blk_enabled() which indicates if block devices are available. This cannot be used in Makefiles, or #if clauses, but can be used in C code. A function is useful because we cannot use CONFIG_IS_ENABLED(BLK) to decide if block devices are needed, since we must consider the legacy block interface, enabled by HAVE_BLOCK_DEVICE Update a few places where it can be used and drop some unnecessary #if checks around some functions in disk/part.c - rely on the compiler's dead-code elimination instead.

2022-04-25Merge branch '2022-04-25-initial-implementation-of-stdboot'Tom Rini
To quote the author: The bootflow feature provide a built-in way for U-Boot to automatically boot an Operating System without custom scripting and other customisation. This is called 'standard boot' since it provides a standard way for U-Boot to boot a distro, without scripting. It introduces the following concepts: - bootdev - a device which can hold a distro - bootmeth - a method to scan a bootdev to find bootflows (owned by U-Boot) - bootflow - a description of how to boot (owned by the distro) This series provides an implementation of these, enabled to scan for bootflows from MMC, USB and Ethernet. It supports the existing distro boot as well as the EFI loader flow (bootefi/bootmgr). It works similiarly to the existing script-based approach, but is native to U-Boot. With this we can boot on a Raspberry Pi 3 with just one command: bootflow scan -lb which means to scan, listing (-l) each bootflow and trying to boot each one (-b). The final patch shows this. With a standard way to identify boot devices, booting become easier. It also should be possible to support U-Boot scripts, for backwards compatibility only. ...

2021-12-09efi: Add a media/block driver for EFI block devicesSimon Glass
Add a block driver which handles read/write for EFI block devices. This driver actually already exists ('efi_block') but is not really suitable for use as a real U-Boot driver: - The operations do not provide a udevice - The code is designed for running as part of EFI loader, so uses EFI_PRINT() and EFI_CALL(). - The bind method probes the device, which is not permitted - It uses 'EFI' as its parent device The new driver is more 'normal', just requiring its platform data be set up in advance.

2021-07-18usb: Enforce DM_USB migration for USB_HOST devices.Tom Rini
As the deadline for migration to DM_USB, when using a USB host controller has now gone two years past the deadline, enforce migration. This is done by: - Ensuring that all host controller options (other than the very legacy old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and OF_CONTROL. - Remove other parts of Kconfig logic that had platforms pick DM_USB. - To keep Kconfig happy, have some select statements test for USB_HOST as well. - Re-order some Kconfig entries and menus so that we can cleanly pick host or gadget roles. For the various HCD options that have platform glue options, group them together and update dependencies in some cases. - As SPL_DM_USB is not required, on platforms that had not yet enabled it, disable it.
