[U-Boot] Getting "Unable to save the rest of sector (196608)" when I turn on Redundant env with CFG_ENV_ADDR_REDUND

[Brian Hutchinson]

Sorry for top post.  This is the third message of the thread being
re-sent in plain text.  I'll also add that the test case below also
hangs on trying to bootm a kernel in flash just as it did in the nfs
boot case of the shown below.
