161 * This function checks whether selected EL provided as an argument
162 * is using the AArch32 ISA. This information might be unavailable
163 * at the current EL status: it hence returns a pair of boolean values:
164 * a first boolean, true if information is available (known),
165 * and a second one, true if EL is using AArch32, false for AArch64.
