2022-09-25sandbox: Convert to use driver model for SCSISimon Glass
At present sandbox is producing a warning about SCSI migration. Drop the legacy code and replace it with a new implementation. Also drop the SATA command, which does not work with driver model. Signed-off-by: Simon Glass <[email protected]>
2022-09-25sandbox: scsi: Move request-handling code to scsi_emulSimon Glass
Move this code into the emulator file so it can be used by multiple drivers. Signed-off-by: Simon Glass <[email protected]>
2022-09-25blk: Rename if_type to uclass_idSimon Glass
Use the word 'uclass' instead of 'if_type' to complete the conversion. Signed-off-by: Simon Glass <[email protected]>
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: Select SPL_LEGACY_BLOCK automaticallySimon Glass
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 <[email protected]>
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: Enable CONFIG_BLK for all mediaSimon Glass
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 <[email protected]>
2022-04-09scsi: call device_probe() after scanningAKASHI Takahiro
Every time a scsi bus/port is scanned and a new block device is detected, we want to call device_probe() as it will give us a chance to run additional post-processings for some purposes. In particular, support for creating partitions on a device will be added. Signed-off-by: AKASHI Takahiro <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2022-02-09Convert CONFIG_SCSI_AHCI_PLAT et al to KconfigSimon Glass
This converts the following to Kconfig: CONFIG_SCSI_AHCI_PLAT CONFIG_SYS_SCSI_MAX_SCSI_ID CONFIG_SYS_SCSI_MAX_LUN CONFIG_SYS_SATA_MAX_DEVICE Drop CONFIG_SCSI for everything except the sandbox build. We only need one build for tests. Signed-off-by: Simon Glass <[email protected]> Reviewed-by: Stefan Roese <[email protected]>
2022-02-09scsi: Drop CONFIG_SYS_SCSI_MAX_DEVICESimon Glass
This is defined based on two other CONFIGs for all boards except sandbox and durian. For sandbox the value does not matter. For durian the value seems excessive. Drop the option completely, to simplify configuration and reduce the number of things we need to convert to Kconfig.

Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <[email protected]>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <[email protected]>

2019-10-23scsi: Add dma direction member to command structureFaiz Abbas

2018-11-14blk: Call part_init() in the post_probe() methodBin Meng
part_init() is currently called in every DM BLK driver, either in its bind() or probe() method. However we can use the BLK uclass driver's post_probe() method to do it automatically. Update all DM BLK drivers to adopt this change. Signed-off-by: Bin Meng <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2018-09-10Remove <inttypes.h> includes and PRI* usages in printf() entirelyMasahiro Yamada
In int-ll64.h, we always use the following typedefs: typedef unsigned int u32; typedef unsigned long uintptr_t; typedef unsigned long long u64; This does not need to match to the compiler's <inttypes.h>. Do not include it. The use of PRI* makes the code super-ugly. You can simply use "l" for printing uintptr_t, "ll" for u64, and no modifier for u32. Signed-off-by: Masahiro Yamada <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <[email protected]>

2017-09-11blk: dm: make blk_create_device() take a number of block instead of a sizeJean-Jacques Hiblot
There is an overflow problem when taking the size instead of the number of blocks in blk_create_device(). This results in a wrong device size: the device apparent size is its real size modulo 4GB. Using the number of blocks instead of the device size fixes the problem and is more coherent with the internals of the block layer.

2017-08-01dm: mmc: Allow disabling driver model in SPLSimon Glass
At present if U-Boot proper uses driver model for MMC, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By default these follow their non-SPL versions, but this can be changed by boards which need it.

2017-07-11dm: scsi: Add operations for SCSI devicesSimon Glass
The SCSI uclass currently has no operations. It just uses the global SCSI functions.

2017-07-11dm: scsi: Add a device pointer to scan_exec(), scsi_bus_reset()Simon Glass

2017-07-11dm: ahci: Unwind the confusing init codeSimon Glass
Two AHCI drivers use SCSI with CONFIG_DM_SCSI. The SCSI uclass calls scsi_low_level_init() which is implemented by ahci.c. If CONFIG_SCSI_AHCI_PLAT is defined it does one thing and if it is not it does something else. We don't need to call through scsi_low_level_init() to get the init completed. Instead, adjust the two drivers to call into AHCI directly. Drop the post-probe init in the SCSI uclass. This means that driver model doesn't need to use scsi_low_level_init(). It is a legacy function and driver model should use a driver's probe() method instead. While we are here, add a comment to the top of the file explaining what ahci.c does.
