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>

|
|
*
|
|
* The boot ROM in these SoCs breaks the PARTITION_CONFIG [179] of
|
|
* Extended CSD register; when switching to the Boot Partition 1, the
|
|
* Boot ROM should issue the SWITCH command (CMD6) with Set Bits for
|
|
* the Access Bits, but in fact it uses Write Byte for the Access Bits.
|
|
* As a result, the BOOT_PARTITION_ENABLE field of the PARTITION_CONFIG
|
|
* is lost. This bug was fixed for PH1-Pro5 and later SoCs.
|
|
*
|
|
* Fixup mmc->part_config here because it is used to determine the
|
|
* partition which the U-Boot image is read from.
