libpayload arm64: Remove dependency on coreboot tables for dma areas
Libpayload should be able to setup its own dma areas and not depend on coreboot tables for passing this information. This patch and next allow libpayload to setup dma areas while performing mmu_init BUG=chrome-os-partner:31634 BRANCH=None TEST=Compiles successfully and dma areas are setup properly with the mmu init patch Change-Id: I5f6fd19a957c7626a2bbe6b826c8987e64ed248f Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 4f3552b8d3439a8b12d1e0b15ef67dcb14b8c96a Original-Change-Id: I44d9f394fa349abd7182c4ba10f1eaefd6e4fdaa Original-Signed-off-by: Furquan Shaikh <furquan@google.com> Original-Reviewed-on: https://chromium-review.googlesource.com/216822 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Original-Tested-by: Furquan Shaikh <furquan@chromium.org> Original-Commit-Queue: Furquan Shaikh <furquan@chromium.org> Reviewed-on: http://review.coreboot.org/8789 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
