[PCS440EP] - Show on the DIAG LEDs, if the SHA1 check failed
- now the Flash ST M29W040B is supported (not tested) - fix the "led" command - fix compile error, if BUILD_DIR is used Signed-off-by: Heiko Schocher <hs@denx.de>

+SHA1 usage:
+-----------
+
+In the U-Boot Image for the pcs440ep board is a SHA1 checksum integrated.
+This SHA1 sum is used, to check, if the U-Boot Image in Flash is not
+corrupted.
+
+The following command is available:
+
+=> help sha1
+sha1 address len [addr] calculate the SHA1 sum [save at addr]
+ -p calculate the SHA1 sum from the U-Boot image in flash and print
+ -c check the U-Boot image in flash
+
+"sha1 -p"
+ calculates and prints the SHA1 sum, from the Image stored in Flash
+
+"sha1 -c"
+ check, if the SHA1 sum from the Image stored in Flash is correct
+
+
+It is possible to calculate a SHA1 checksum from a memoryrange with:
+
+"sha1 address len"
+
+If you want to store a new Image in Flash for the pcs440ep board,
+which has no SHA1 sum, you can do the following:
+
+a) cp the new Image on a position in RAM (here 0x300000)
+ (for this example we use the Image from Flash, stored at 0xfffa0000 and
+ 0x60000 Bytes long)
+
+"cp.b fffa0000 300000 60000"
+
+b) Initialize the SHA1 sum in the Image with 0x00
+ The SHA1 sum is stored in Flash at:
+ CFG_MONITOR_BASE + CFG_MONITOR_LEN + SHA1_SUM_POS
+ for the pcs440ep Flash: 0xfffa0000 + 0x60000 + -0x20
+ = 0xffffffe0
+ for the example in RAM: 0x300000 + 0x60000 + -0x20
+ = 0x35ffe0
+
+ note: a SHA1 checksum is 20 bytes long.
+
+"mw.b 35ffe0 0 14"
+
+c) now calculate the SHA1 sum from the memoryrange and write
+ the calculated checksum at the right place:
+
+"sha1 300000 60000 35ffe0"
+
+Now you have a U-Boot-Image for the pcs440ep board with the correct SHA1 sum.
+
+If you do a "./MAKEALL pcs440ep" or a "make all" to get the U-Boot image,
+the correct SHA1 sum will be automagically included in the U-Boot image.
