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>

# This script tests U-Boot's FAT filesystem code's ability to read non-
|
|
# contiguous files.
|
|
|
|
# When porting the ff.c FAT parsing code into U-Boot, it was found that ff.c
|
|
# always reads files cluster-by-cluster, which results in poor performance.
|
|
# This was solved by adding a patch to ff.c to coalesce reads of adjacent
|
|
# clusters. Since this patch needed to correctly handle non-contiguous files,
|
|
# this test was written to validate that.
|
|
#
|
|
# To execute the test, simply run it from the U-Boot source root directory:
|
|
#
|
|
# cd u-boot
|
|
# ./test/fs/fat-noncontig-test.sh
|
|
#
|
|
# The test will create a FAT filesystem image, record the CRC of a randomly
|
|
# generated file in the image, build U-Boot sandbox, invoke U-Boot sandbox to
|
|
# read the file and validate that the CRCs match. Expected output is shown
|
|
# below. The important part of the log is the penultimate line that contains
|
|
# either "PASS" or "FAILURE".
