The current ITS driver works fine as long as normal memory and GICR regions are located within the lower 48bit (>=0 && <2^48) physical address space. Some of the registers GICR_PEND/PROP, GICR_VPEND/VPROP and GITS_CBASER are handled properly but not all when configuring the hardware with 52bit physical address. This patch does the following changes to support 52bit PA. -Handle 52bit PA in GITS_BASERn. -Fix ITT_addr width to 52bits, bits[51:8]. -Fix RDbase width to 52bits, bits[51:16]. -Fix VPT_addr width to 52bits, bits[51:16]. Definition of the GITS_BASERn register when ITS PageSize is 64KB: -Bits[47:16] of the register provide bits[47:16] of the table PA. -Bits[15:12] of the register provide bits[51:48] of the table PA. -Bits[15:00] of the base physical address are 0.
