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>

2017-09-15fs: add fs_readdir()Rob Clark
Needed to support efi file protocol. The fallback.efi loader wants to be able to read the contents of the /EFI directory to find an OS to boot. Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other fs APIs, this is stateful (ie. state is held in the FS_DIR "directory stream"), to avoid re-traversing of the directory structure at each step. The directory stream must be released with closedir() when it is no longer needed.

2016-03-14dm: part: Convert partition API use to linker listsSimon Glass
We can use linker lists instead of explicitly declaring each function. This makes the code shorter by avoiding switch() statements and lots of header file declarations. While this does clean up the code it introduces a few code issues with SPL. SPL never needs to print partition information since this all happens from commands. SPL mostly doesn't need to obtain information about a partition either, except in a few cases. Add these cases so that the code will be dropped from each partition driver when not needed. This avoids code bloat. I think this is still a win, since it is not a bad thing to be explicit about which features are used in SPL. But others may like to weigh in.

2016-01-13mmc: store hwpart in the block deviceStephen Warren
This will allow us to have multiple block device structs each referring to the same eMMC device, yet different HW partitions. For now, there is still a single block device per eMMC device. As before, this block device always accesses whichever HW partition was most recently selected. Clients wishing to make use of multiple block devices referring to different HW partitions can simply take a copy of this block device once it points at the correct HW partition, and use each one as they wish. This feature will be used by the next patch. In the future, perhaps get_device() could be enhanced to return a dynamically allocated block device struct, to avoid the client needing to copy it in order to maintain multiple block devices. However, this would require all users to be updated to free those block device structs at some point, which is rather a large change. Most callers of mmc_switch_part() wish to permanently switch the default MMC block device's HW partition. Enhance mmc_switch_part() so that it does this. This removes the need for callers to do this. However, common/env_mmc.c needs to save and restore the current HW partition. Make it do this more explicitly. Replace use of mmc_switch_part() with mmc_select_hwpart() in order to remove duplicate code that skips the call if that HW partition is already selected.
