2014-08-04ArmPkg/ArmSmcLib: Fixed SMC helper functionsOlivier Martin
The SMC helper functions were buggy as they were assuming that the values in x1-x7 registers were preserved across an SMC call, which is not the case. This patch fixes this issue. It also simplifies the code by providing only 1 version of the SMC helper function. We used to have 4 versions depending on the number of arguments. The problem with this approach was that the number of arguments also dictated the number of return values, which is completely unrelated. E.g. you can have an SMC call that takes 1 argument but returns 4 values.

2014-05-08ArmPkg/BdsLib: Fix booting with partial pathsMark Salter
Boot entries created by efibootmgr may contain a partial device path to the EFI application to boot. These entries begin with a partition device path whereas entries created via ARM Boot Manager contain a full path to the EFI application. The ARM BDS code will fill in the missing parts of this partial device path as it does for removeable device paths. This allows the application to be loaded and started. However, the current code passes the original partial device path to gBS->LoadImage() and thus LoadImage is unable to find a DeviceHandle for the path. This means the application being booted cannot find the boot device from the Loaded Image Protocol structure. In the case of grub, this prevents the grub config file from being found. This patch fixes this by making sure the full path is propagated back to the caller of gBS->LoadImage() so that a proper DeviceHandle gets passed to the application being booted.

2014-04-23ArmPkg/CpuDxe: Restore AArch64 system registers before returning from exceptionoliviermartin
Current EDK2 source code does actually trigger nested interrupted (even if the PI spec says interrupt should not be nested). This issue has highlighted the lack of restoring ELR_EL2/ELR_EL1 register.

2014-04-02ArmPkg: Fixed GetEnvironmentVariable() when the UEFI Variable did not existOlivier Martin
The function was allocating a buffer for the read value from the UEFI Variable. But it was returning the pointer of the default value when the variable was not present. It could cause error when the default value and the returned value were free when these addresses were the same (double FreePool on the same address).
