2015-07-14ArmPkg/BdsLib: Remove Linux loader from BdsLibOlivier Martin
This change removes the embedded Linux Loder from BdsLib. BdsLib becomes OS agnostic. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Olivier Martin <Olivier.Martin@arm.com> Reviewed-by: Ronald Cron <Ronald.Cron@arm.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@17969 6f19259b-4bc3-4df7-8a09-765794883524
2014-12-12ArmPkg/BdsLib: Update the size of the Device Tree before booting LinuxOlivier Martin
The memory reserved to load the device tree is over-allocated when UEFI loads the blob to update the device tree with additional information such as the command line, the initrd, etc. This change ensures the total size declared by the device tree matches the actual data (and not the over-allocated size value).

2014-07-15ArmPkg/BdsLib: Removed PSCI discoverability from the Linux loaderOlivier Martin
Some platforms might decide to not support PSCI in their FDT-aware Linux system even if their firmware supports it. It is the responsibility of the platform engineer to provide the appropriate FDT. The PCD gArmTokenSpaceGuid.PcdArmPsciSupport is not required anymore.

2013-11-28ArmPkg/BdsLib: Fixed the alignment of the relocated Device TreeOlivier Martin
When the Device Tree was loaded above the 32bit address space the operation: *RelocatedFdt = ALIGN ((UINT64)*RelocatedFdt, (UINT32)FdtAlignment); was returning an incorrect address.

2013-06-27ArmPkg/BdsLib: Fixed manipulation of the Memory Map returned by GetMemoryMap()Olivier Martin
The UEFI specification mandates that software uses the DescriptorSize returned by the GetMemoryMap() function to find the start of each EFI_MEMORY_DESCRIPTOR in the MemoryMap array. This allows for future expansion of the EFI_MEMORY_DESCRIPTOR.

* Fix name of 'device_type' and 'migrate' properties. * Fix 'reg' property. It is supposed to contain the CPU MPIDR of the CPU being described. * Fix byte ordering of data in 'psci' node. * Fix some problems regarding the size of data.
