# IXP4XX_PATCHES - full list of patches to apply, to add files
# generate a patch against /dev/null
-# IXP4XX_SUFFIX - the suffix to add after 'zImage-' in the
-# deploy/images directory, should identify the machines the
-# kernel will run on, ixp4xx[lb] for generic kernels (le or
-# be). Controls the package architecture of the ipk.
-# IXP4XX_MACHID - if set the kernel will be forced to use this
-# machine id and be forced to LE on LE systems - please always
-# remember to override IXP4XX_SUFFIX if this is done, the kernel
-# will simply not work on other machines.
-# IXP4XX_LEFIXUP - if set prepend the LE fixup code to the kernel
-# and byte swap (quad word) the whole kernel image for a BE
-# boot loader
-#
-# If you set CMDLINE_ROOT you should *also* change IXP4XX_SUFFIX
-# because the resultant kernel may not work on other systems.

+A more robust test for swapped RedBoot FIS directory partitions. This
+changes the test to check the flash_base value for the FIS directory,
+since we know where the FIS directory base is we can work out whether
+the flash address stored in the directory itself is byte swapped under
+most circumstances. If the value is 0 the directory is at the start
+of the flash and the test fails. In this case the fallback is to use
+the original test made slightly more robust.
