The values of CP15BEN, nTWI & nTWE bits in SCTLR_EL1 are architecturally unknown if EL3 is AARCH64 whereas they reset to 1 if EL3 is AArch32. This might be a compatibility break for legacy AArch32 normal world software if these bits are not set to 1 when EL3 is AArch64. This patch enables the CP15BEN, nTWI and nTWE bits in the SCTLR_EL1 if the lower non-secure EL is AArch32. This unifies the SCTLR settings for lower non-secure EL in AArch32 mode for both AArch64 and AArch32 builds of Trusted Firmware.
