[edk2] [platforms: PATCH v2 04/12] Marvell/Armada: Use 4k/64k aligned sections for DXE/DXE-rt modules
Posted by Marcin Wojtas 7 years, 2 months ago
From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

Enable strict memory protection at boot time and under the OS, by using
4 KB section alignment for DXE_DRIVER, UEFI_DRIVER and UEFI_APPLICATION
modules, and 64 KB alignment for DXE_RUNTIME_DRIVER modules. Note that
the latter is mandated by the UEFI spec.
