From ead1274b7f9578e346b3cdcb3d9e2002ef8f0e75 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20Br=C3=BCns?= Date: Sun, 9 Oct 2016 22:17:18 +0200 Subject: efi_loader: Move efi_allocate_pool implementation to efi_memory.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We currently handle efi_allocate_pool() in our boot time service file. In the following patch, pool allocation will receive additional internal semantics that we should preserve inside efi_memory.c instead. As foundation for those changes, split the function into an externally facing efi_allocate_pool_ext() for use by payloads and an internal helper efi_allocate_pool() in efi_memory.c that handles the actual allocation. While at it, change the magic 0xfff / 12 constants to the more obvious EFI_PAGE_MASK/SHIFT defines.
