[PATCH 0/1] enable Intel Alderlake RST VMD configuration

["Oldřich Jedlička" <oldium.pro@gmail.com>]

Hi,

I was testing RAID 0 on my Dell Precision 3570 with Intel i7-1255U
Alderlake processor. The mdadm tool did not work initially (the
RAID was not recognised), but I was able to get the RAID working when
I simply set IMSM_NO_PLATFORM=1. Then I tracked the issue down to UEFI
variables and discovered that the platform newly uses the 'RstVmdV'
name. This exactly same variable was used in recent patch series called
"mdadm-CI for-jes/20220728", so I updated the code to recognise the new
variable name also for VMD controller case. I then verified the change
by first running it in a debugger and then by putting it to initrd on
Fedora 36 (kernel 5.17). The startup was fine, the RAID 0 was correctly
setup.

I based my work on top of "mdadm-CI for-jes/20220728" patch series,
it is required in order to apply the patch.

Regards,
Oldrich.
