2014-11-11ArmPkg: Ensured the stack is always quad-word alignedOlivier Martin1-4/+4
From the AArch64 Procedure Call Standard (ARM IHI 0055B): 5.2.2.1 Universal stack constraints At all times the following basic constraints must hold: - SP mod 16 = 0. The stack must be quad-word aligned.

2014-08-04ArmPkg/ArmSmcLib: Fixed SMC helper functionsOlivier Martin1-55/+18
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.
