* ArmPkg: move RVCT PLATFORM_FLAGS override into ArmHvcLib/ArmSmcLibArd Biesheuvel2017-11-161-0/+3
| | | | | | | | | | | | | Currently, each ARM platform built with RVCT that uses ArmHvcLib or ArmSmcLib needs to specify a CPU target that implements both the security and virtualization extensions, so that the assembler does not choke on the 'hvc' and 'smc' instructions in ArmHvcLib/ArmSvcLib. Let's move these overrides into the module .INFs so we can lift this requirement at the platform side.

* ArmPkg: copy/paste fixes in ARM ArmHvcLib/ArmSmcLibLeif Lindholm2017-04-131-1/+1
| | | | | | | | | | | | | ARM ArmHvcLib looks like it was created from copy of ArmSmcLib which looks like it was created from a copy of the AArch64 version. Both of these files include AsmMacroIoLibV8.h instead of AsmMacroIoLib.h, although since they only use macros that are identical between the two, there was no functional issue caused by this.

* ArmPkg: Ensured the stack is always quad-word alignedOlivier Martin2014-11-111-4/+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.

* ArmPkg/ArmSmcLib: Fixed SMC helper functionsOlivier Martin2014-08-043-157/+74
| | | | | | | | | | | | | | | | | | | | 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.
