[edk2-devel] [PATCH v3 1/8] DynamicTablesPkg: AML Code generation for memory ranges

PierreGondois pierre.gondois at arm.com
Thu Nov 18 17:42:40 UTC 2021


From: Pierre Gondois <Pierre.Gondois at arm.com>

Add helper functions to generate AML Resource Data describing memory
ranges. Memory ranges can be one, double or four words long. They
can be of 'normal', IO or bus number memory type. The following
APIs are exposed:
 - AmlCodeGenRdDWordIo ()
 - AmlCodeGenRdDWordMemory ()
 - AmlCodeGenRdWordBusNumber ()
 - AmlCodeGenRdQWordMemory ()
