// Write-Through support *not* available
// Write-Back support available.
// Read allocation support available.
// Write allocation support available.
//Note: You should use the Shareable attribute carefully.
//For cores without coherency logic (such as SCU) marking a region as shareable forces the processor to not cache that region regardless of the inner cache settings.
//Cortex-A versions of RTX use LDREX/STREX instructions relying on Local monitors. Local monitors will be used only when the region gets cached, regions that are not cached will use the Global Monitor.
//Some Cortex-A implementations do not include Global Monitors, so wrongly setting the attribute Shareable may cause STREX to fail.
//Recall: When the Shareable attribute is applied to a memory region that is not Write-Back, Normal memory, data held in this region is treated as Non-cacheable.
//When SMP bit = 0, Inner WB/WA Cacheable Shareable attributes are treated as Non-cacheable.
//When SMP bit = 1, Inner WB/WA Cacheable Shareable attributes are treated as Cacheable.
//Following MMU configuration is expected
//SCTLR.AFE == 1 (Simplified access permissions model - AP[2:1] define access permissions, AP[0] is an access flag)
//SCTLR.TRE == 0 (TEX remap disabled, so memory type and attributes are described directly by bits in the descriptor)
//Domain 0 is always the Client domain
//Descriptors should place all memory in domain 0
