The DTB binary can be embedded in the firmware image by adding the following to the platform .fdf file: FILE FREEFORM = 25462CDA-221F-47DF-AC1D-259CFAA4E326 { SECTION RAW = SomePkg/path/to/foo.dtb } Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel --- v2: fixup various errors and rough edges pointed out by Laszlo EmbeddedPkg/EmbeddedPkg.dec | 6 + EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformDxe.inf | 65 ++++++ EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformDxe.h | 31 +++ EmbeddedPkg/Include/Guid/DtPlatformDefaultDtbFile.h | 23 +++ EmbeddedPkg/Include/Guid/DtPlatformFormSet.h | 23 +++ EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformHii.vfr | 51 +++++ EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformDxe.c | 216 ++++++++++++++++++++ EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformHii.uni | 27 +++ 8 files changed, 442 insertions(+) diff --git a/EmbeddedPkg/EmbeddedPkg.dec b/EmbeddedPkg/EmbeddedPkg.dec index 29736fb4a71d..871fc5ff4016 100644 --- a/EmbeddedPkg/EmbeddedPkg.dec +++ b/EmbeddedPkg/EmbeddedPkg.dec @@ -62,6 +62,12 @@ [Guids.common] ## Include/Guid/PlatformHasDeviceTree.h gEdkiiPlatformHasDeviceTreeGuid = { 0x7ebb920d, 0x1aaf, 0x46d9, { 0xb2, 0xaf, 0x54, 0x1e, 0x1d, 0xce, 0x14, 0x8b } } + # HII form set GUID for DtPlatformDxe driver + gDtPlatformFormSetGuid = { 0x2b7a240d, 0xd5ad, 0x4fd6, { 0xbe, 0x1c, 0xdf, 0xa4, 0x41, 0x5f, 0x55, 0x26 } } + + # File GUID for default DTB image embedded in the firmware volume + gDtPlatformDefaultDtbFileGuid = { 0x25462cda, 0x221f, 0x47df, { 0xac, 0x1d, 0x25, 0x9c, 0xfa, 0xa4, 0xe3, 0x26 } } + [Protocols.common] gHardwareInterruptProtocolGuid = { 0x2890B3EA, 0x053D, 0x1643, { 0xAD, 0x0C, 0xD6, 0x48, 0x08, 0xDA, 0x3F, 0xF1 } } gEfiDebugSupportPeriodicCallbackProtocolGuid = { 0x9546e07c, 0x2cbb, 0x4c88, { 0x98, 0x6c, 0xcd, 0x34, 0x10, 0x86, 0xf0, 0x44 } } diff --git a/EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformDxe.inf b/EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformDxe.inf new file mode 100644 index 000000000000..aa1d3abb4012 --- /dev/null +++ b/EmbeddedPkg/Drivers/DtPlatformDxe/DtPlatformDxe.inf @@ -0,0 +1,65 @@ +## @file +# +# Copyright (c) 2017, Linaro, Ltd.
