Subject: vc/amd/agesa/f15tn: add 933 MHz to
GfxMemClockFrequencyDefinitionTable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fix is required to avoid the division-by-zero error described at
https://mail.coreboot.org/pipermail/coreboot/2014-March/077418.html
while trying to run the DDR3 memory at 1866 MT/s (933 MHz).
With this fix in place, ASUS A88XM-E boots fine with RAM at 1866 MT/s.
