[edk2] [platforms: PATCH 2/8] Marvell/Armada: Increase preallocated memory region size
Posted by Marcin Wojtas 7 years, 2 months ago
From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

In order to prevent fragmentation of the UEFI memory map, increase the
sizes of the preallocated regions. Note that this does not increase the
memory footprint of UEFI, it just modifies it allocation policy to keep
similar region types together.
