Increase TPL to TPL_NOTIFY to allow for use if caller is > TPL_CALLBACK.
This allows services like variable services that run at TPL_NOTIFY to
be hosted on ScsiDisks (i.e. UFS)
Aligns with the eMMC driver that also uses a higher TPL.
This change was made in 3b1d8241d0dac25c5e678c364fa2754ac1731060
Resuming this PATCH to see if there are any additional thoughts on this.
In response to the query about DXE/BDS services we have some internal
connection logic that runs in DXE to connect the devices that are needed for
arch services that have to be connected prior the end of dxe.
Thanks,
Jeff

Hello Mike, Liming and Star,
Do you have suggestions for the below question raised from Jeff Brasen:
" The core of the issue I am trying to solve it support variable services on a
UFS device. When the UFS blockIO is invoked from variable services it is not
allowed (which does
Jeff's statement about the TPLs in variable and PCD drivers seems correct, not
sure the impact to change them. No good idea from me about the TPL change in
ScsiDisk. 😊
Side question: Variable service is an arch service which should be ready at DXE
phase, ScsiDisk is a driver model driver which
