blk: blkmap: Add basic infrastructure

2023-04-05T14:54:47Z

blkmaps are loosely modeled on Linux's device mapper subsystem. The basic idea is that you can create virtual block devices whose blocks can be backed by a plethora of sources that are user configurable. This change just adds the basic infrastructure for creating and removing blkmap devices. Subsequent changes will extend this to add support for actual mappings.

dm: blk: mmc: Tidy up some Makefile rules for SPL

2022-10-31T15:02:44Z

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.

blk: Hide the BLK and SPL_LEGACY_BLOCK options

2022-09-16T15:05:16Z

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.

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

efi: Add a media/block driver for EFI block devices

2021-12-09T19:43:25Z

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.
