The tlbimvaa operation (invalidate unified TLB by MVA, all address
space identifiers) is only available on armv7 processors that support
Multiprocessing Extensions. When used on processors that do not support
the extensions it causes an "undefined instruction" exception.
This patch changes the MMU table entry filling code to use the tlbimva
(invalidate unified TLB entry by MVA and address space identifier)
operation for invalidating TLB entries, which is supported on all armv7
processors.
As address space identifiers are not used in TLB entries in coreboot
(all entries are set as global), these two operations can safely be
used interchangeably. The ASID value supplied to the operation is not
checked for global TLB entries.
More information as well as the data formats for the tlbimvaa and
tlbimva operations are detailed in the "ARM Architecture Reference
Manual ARMv7-A" edition, issue "C.c" page B4-1747.
