From 2ef2b01e07c02db339f34004445734a2dbdd80e1 Mon Sep 17 00:00:00 2001 From: AJFISH Date: Sun, 6 Dec 2009 01:57:05 +0000 Subject: Adding support for BeagleBoard. ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers. EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell. BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9518 6f19259b-4bc3-4df7-8a09-765794883524 --- .../PrePiExtractGuidedSectionLib.c | 247 +++++++++++++++++++++ .../PrePiExtractGuidedSectionLib.inf | 24 ++ 2 files changed, 271 insertions(+) create mode 100644 EmbeddedPkg/Library/PrePiExtractGuidedSectionLib/PrePiExtractGuidedSectionLib.c create mode 100644 EmbeddedPkg/Library/PrePiExtractGuidedSectionLib/PrePiExtractGuidedSectionLib.inf (limited to 'EmbeddedPkg/Library/PrePiExtractGuidedSectionLib') diff --git a/EmbeddedPkg/Library/PrePiExtractGuidedSectionLib/PrePiExtractGuidedSectionLib.c b/EmbeddedPkg/Library/PrePiExtractGuidedSectionLib/PrePiExtractGuidedSectionLib.c new file mode 100644 index 0000000000..b635fa0d9e --- /dev/null +++ b/EmbeddedPkg/Library/PrePiExtractGuidedSectionLib/PrePiExtractGuidedSectionLib.c @@ -0,0 +1,247 @@ +/** @file + + Copyright (c) 2008-2009, Apple Inc.
