[coreboot] blobs: is there a reason for intel microcode version 20150121?

I am empirical/practical guy, mit wenig Zeit (zu viele Dinge zu tun), dann
ich sole super schnell Denken machen (taking some German practice as well,
I must, it is bad).

I see some of earlier MCU packet downloads, so these are the following:

As we all in Coreboot now see (attn: Martin, Patrick, Ron, Stefan), the
latest and greatest you pointed to should be taken and implemented. It
is, (Mein
Gott), ~ 4,5x size
of old currently used (20150121), so, my best guess, action is here needed
on behalf of above mentioned people (to enrich Coreboot MCU database).

NOPE! I did/do not suggest that (it is, maybe, language limitation, I feel
all the time in German). I suggest to add the 4th I/F (*dump_cpuids*) in
the update-microcodes.sh_

Then, the following file I got from it on 20150121 (attached to this email

Furthermore, since you are targeting Haswell, luckily enough, my HP
EliteBook 840 G1 is based upon i3-4300U Haswell. What do I have here?


[user at localhost microcode]$ uname -r
[user at localhost microcode]$ dmesg | grep i5
*[    0.100550] smpboot: CPU0: Intel(R) Core(TM) i5-4300U CPU @ 1.90GHz
(family: 0x6, model: 0x45, stepping: 0x1)*
[user at localhost microcode]$

This is CPUID 0x40651 (I know this by heart, no questions asked)! ;-)

Now, if you search the file on 40651 I have created and attached on this
email, you'll get the following:

Model: 40651(4065x)  Microcode: microcode-m7240651_0000001c.h (copied)

I guess, for one, who is smart, I gave even redundant info. ;-)

Good Luck,
Zoran Stojsavljevic

PS. Please, google what MCU is (Micro Code Unit and purpose of it), I am
too lazy to write about it!
