[Skiboot] [PATCH v8] pflash option to retrieve PNOR partition flags
Michael Tritz
mtritz at us.ibm.com
Thu Jul 13 06:31:49 AEST 2017
This commit extends pflash with an option to retrieve and print
information for a particular partition, including the content from
"pflash -i" and a verbose list of set miscellaneous flags. -i option
is also updated to print a short list of flags in addition to the
ECC flag, with one character per flag. A test of the new option is
included in libflash/test.
V8: Make check target now depends on having built pflash. Updated
the path to pflash in the test script. Test script runs now.
V7: Fixed whitespace error and changed permissions on test script
V6: Reverted change to has_ecc() to avoid breaking libffs
