Add cputype definitions for Cortex-A520AE. The definition can be found in Cortex-A520AE TRM, https://developer.arm.com/documentation/107726/0001/ as part of MIDR_EL1 bit descriptions. This is going to be used in the bbml3 support list. Signed-off-by: Linu Cherian <redacted> --- arch/arm64/include/asm/cputype.h | 2 ++ 1 file changed, 2 insertions(+)
