memcontrol clear -b 0x... -l 0x....
Where the argument to -b is the first address listed from memcontrol
list, and the -l argument is the second address in the list.
E.g. for my ranges:
0xd0000000/0x10000000 BIOS uncacheable set-by-firmware active
0xe0000000/0x20000000 BIOS uncacheable set-by-firmware active
memcontrol clear -b 0xd0000000 -l 0x10000000
memcontrol clear -b 0xe0000000 -l 0x20000000
No adverse reaction so far...
