2016-04-14mb/asus/kgpe-d16|kcma-d8: Do not assign IRQ to LPC HW monitorTimothy Pearson
On specific revisions of the ASUS KGPE-D16 (> 1.03G) there is a high (< 1:10) chance of lockup from spurious HW monitor IRQs during LPC configuration. This was originally erroneously identified as a bug within the SP5100 southbridge due to serial console buffering moving the hang slightly before HW monitor setup. It is currently unknown how changing the CBFS layout / code size was able to alter the frequency of the lockup occuring; this odd characteristic made debugging extremely difficult, and it also indicates testing across multiple PCB revisions will be neded to verify that the bug has been completely resolved. It is highly likely that the KCMA-D8 is also affected. As there does not seem to be a reason to keep the HW monitor IRQ enabled, simply disable it on both mainboards. This configuration has passed burn-on power cycle testing with no lockups noted. All other tests noted a lockup in under 25 power cycles or so, with failure typically occuring in under 5 power cycles; the affected Rev. 1.04 KGPE-D16 has cycled 25 times times using this patch with only one failure finally noted. This final failure may have in fact been related to SP5100 Erratum 18 as the frequency is more in line with the errata document guidelines.

2016-02-05mainboard/asus/kcma-d8: Copy ASUS KGPE-D16 for initial support workTimothy Pearson
Also updated KGPE-D16 strings to KCMA-D8 throughout the copy to work around Jenkins failures caused by an unmodified clone.
