Re: [edk2-devel] [edk2-platforms] Intel/MinPlatformPkg: resolve MmUnblockMemoryLib

[Kun Qin]

Hi Zhiguang,

I have already sent this patch series to resolve dependencies in 
edk2-platform (although the change is slightly different):
https://edk2.groups.io/g/devel/message/72645

Specifically:
https://edk2.groups.io/g/devel/message/72646

Could you please let me know if the change above resolves the dependency 
issue for you?

The patch series have 2 other patches not being reviewed yet. I plan to 
send out another round tomorrow to include reviewed-by tags. But please 
let me know if you prefer your change below to check in first, I will 
just drop my patch #1 when sending v2.

Thanks,
Kun

Hi Kun,
Your patch is ok for me. Please keep this change in your patch series.

Hi All, 
Please ignore this patch since the same solution is already included in Kun's patch serials.
