2020-08-07dm: Rename DM test flags to make them more genericSimon Glass
The test flags used by driver model are currently not available to other tests. Rather than creating two sets of flags, make these flags generic by changing the DM_ prefix to UT_ and moving them to the test.h header. This will allow adding other test flags without confusion.

2020-08-03dm: core: Drop header files from dm/test.hSimon Glass
These header file should not be included in other header files. Remove them and add to each individual file. Add test/test.h to test/ui.h since that is a reasonable place. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-11-14test: dm: blk: Correct blk_base test caseBin Meng
The blk_base test case creates a USB mass storage block device with the Sandbox host block device as its parent. This does not make any sense and causes potential issue, for example if the test case tries to read/write anything on the USB mass storage block device it will definitely fail as its parent is not on USB bus at all. Correct the test case by creating another Sandbox host block device instead of the USB mass storage one and adjust the case accordingly.

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 <trini@konsulko.com>
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.

2017-06-09dm: blk: Add a way to obtain a block device from its parentSimon Glass
Many devices support a child block device (e.g. MMC, USB). Add a convenient way to get this device given the parent device. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2017-06-01dm: blk: Improve block device claimingSimon Glass
The intention with block devices is that the device number (devnum field in its descriptor) matches the alias of its parent device. For example, with: aliases { mmc0 = "/sdhci@700b0600"; mmc1 = "/sdhci@700b0400"; } we expect that the block devices for mmc0 and mmc1 would have device numbers of 0 and 1 respectively. Unfortunately this does not currently always happen. If there is another MMC device earlier in the driver model data structures its block device will be created first. It will therefore get device number 0 and mmc0 will therefore miss out. In this case the MMC device will have sequence number 0 but its block device will not. To avoid this, allow a device to request a device number and bump any existing device number that is using it. This all happens during the binding phase so it is safe to change these numbers around. This allows device numbers to match the aliases in all circumstances. Add a test to verify the behaviour. Signed-off-by: Simon Glass <sjg@chromium.org>

Sometimes it is useful to be able to find a block device without also probing it. Add a function for this as well as the associated test. Signed-off-by: Simon Glass <sjg@chromium.org>
