# 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".
