+description = """We used differential testing to compared the instruction consistency (ARMv7) between QEMU and raspberry pi 2B in system level and some inconsistency in system regisiter was detected.
+
+1. CCSIDR--Cache Size ID Registers
+
+   **Inconsistency**
+
+   - CCSIDR in QEMU: 0x701fe00a--Associativity: 2, Number of sets:256
+
+   - CCSIDR in  Raspi2B: 0x700fe01a--Associativity: 4, Number of sets:128
+
+   **Tested Instruction sample**
+
+   - MRC_T1A1_A 11101110001100000000111100010000 0xee300f10
+
+   According to ARMv7 Manual B4.1.19 encoding, the NumSets and Associativity are set different bewteen QEMU when emulating raspi2b and raspi2b.
+
+   The CCSIDR is set in the function`cortex_a7_initfn(Object *obj)` in target/arm/cpu_tcg.c for cortex_a7. 
+
+2. DBGDRAR--Debug ROM Address Register
+
+   **Inconsistency**
+
+   - DBGDRAR in QEMU: 0x0 --Invalid
+
+   - DBGDRAR in  Raspi2B: 0x40020003--Valid
+
+   According to ARMv7 Manual C11.11.16 encoding, the DBGDRAR in qemu is invalid.
+
+   **Tested Instruction sample**
+
+   - MRC_T1A1_A 11101110000100010001111000010000 0xee111e10"""
