PATCH v4 1/1 Update U-Boot's build timestamp on every compile

Use the GNU 'date' command to auto-generate a new U-Boot timestamp on every compile.

Signed-off-by Peter Tyser <[email protected]>

---
Changes since v1:
* Split up U_BOOT_DATE define (date and time) into U_BOOT_DATE (day, month, year) and U_BOOT_TIME (time of day) defines
* Updated all architetures/boards

Changes since v2:
* Placed U_BOOT_DATE and U_BOOT_TIME defines in
timestamp_autogenerated.h.
* Added include/timestamp.h

Changes since v3:
* rebased on TOT
* removed 2 whitespace violations

This means any file that uses CONFIG_CDP_VERSION will need to include timestamp.h, which it didn't before. You added the includes where needed?

I was following the lead of version.h, which has the same issue you spotted. I'll fix both in the next rev.

This means any file that uses CONFIG_CDP_VERSION will need to include timestamp.h, which it didn't before. You added the includes where needed?

Yes, it is only used in net.c which was updated with:
+#if defined(CONFIG_CDP_VERSION)
+#include <timestamp.h>
+#endif

Thanks for the comments Trent. I'll resubmit v5 shortly. Peter
