ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the size of translation tables by increasing the maximum permitted value of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and VSTCR_EL2. This feature is supported in AArch64 state only. This patch adds support for this feature to both versions of the translation tables library. It also removes the static build time checks for virtual address space size checks to runtime assertions.
