 Subject: [PATCH] env/fat.c: allow loading from a FAT partition on the MMC boot
  device
 
 I don't want to have to specify the device; only the partition.
 
+This allows me to use the same image on internal eMMC or SD card for
+Banana Pi R2, and it finds its own environment either way.
+
 Signed-off-by: David Woodhouse <dwmw2@infradead.org>
+[trini: Add #if/#else/#endif logic around CONFIG_SYS_MMC_ENV_DEV usage,
+        whitespace changes]
