+Subject: [PATCH] nvmem: u-boot-env: align endianness of crc32 values
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch fixes crc32 error on Big-Endianness system by conversion of
+calculated crc32 value.
+
+Little-Endianness system:
+
+  obtained crc32: Little
+calculated crc32: Little
+
+Big-Endianness system:
+
+  obtained crc32: Little
+calculated crc32: Big
+
+log (APRESIA ApresiaLightGS120GT-SS, RTL8382M, Big-Endianness):
+
+[    8.570000] u_boot_env 18001200.spi:flash@0:partitions:partition@c0000: Invalid calculated CRC32: 0x88cd6f09 (expected: 0x096fcd88)
+[    8.580000] u_boot_env: probe of 18001200.spi:flash@0:partitions:partition@c0000 failed with error -22

+Fixes: f955dc1445069 ("nvmem: add driver handling U-Boot environment variables")
