   RedBoot for Starter-Kit V (STK5)
   Ka-Ro Electronics GmbH
 
+  The RedBoot source code is available via git from:
+  git://git.karo-electronics.de/karo-tx-redboot.git
+  in the 'master' branch
+
   ===========================================================
+ v1.5.8 (2014-08-08)
+  git tag: KARO-TX51-2014-08-08
+  Changes:
+    TX51:
+      - explicitly program the padctl settings for SDRAM and NAND from
+        the DCD to ensure correct settings after soft reset.
+      - reduce DSE values for SDRAM and NAND control lines for better
+        error margins in NAND detection and SDRAM stress test.
+      - Revert the change of the NFC clock frequency from the previous
+        release, as this is not necessary any more with the improved
+        pad settings.
+
+ v1.5.7 (2014-07-01)
+  git tag: KARO-TX53-2014-04-09
+  Changes:
+    TX51:
+      - reduce the NFC clock frequency to 16MHz to prevent NAND chip
+        detection errors at cold temperatures with the Toshiba
+        TC58NYG0S3EBAI4 flash chips
+    TX53:
+      - adjust core voltage according to selected frequency upon boot
+      - remove bogus DDR3 Write leveling calibration that is not
+        required due to the PCB layout and does not work with the
+        NT5CB128M16FP-DII chips
+
+    TX27:
+      - committed the missing source code changes for v1.5.5 that were
+        only committed to the legacy CVS repository but missing in git.
+
+ v1.5.6 (2013-08-19)
+  Changes:
+    TX53:
+      - updated SDRAM initialization to work with NT5CB128M16 mask
+        revision 'F' (see: TX53-PCN-2013-08.pdf)
+
+ v1.5.5 (2012-09-25)
+  Changes:
+    TX27:
+      - workaround for MPLL restart problem in i.MX27 date code 1230
+        and newer (see /Documentation/TX27PCN2012-09.pdf).
+      - wait after enabling wdt clock in HAL_PLATFORM_RESET() to
+        prevent possible hang in 'reset' command.
+      - fix trampoline code change for archs that use the default
+        CYGARC_HAL_MMU_OFF macro.
