ArmVirtPkg/PrePi: remove mSystemMemoryEnd

2016-10-24T14:57:25+00:00

Recording the top of SEC visible system memory in a global variable is
not necessary, and violates the constraints of the SEC/PEI environment,
given that it may execute from NOR flash. So remove it.

ArmVirtPkg: clean up assembly source files

2016-08-11T10:29:31+00:00

This updates all assembly source files under ArmVirtPkg to mark
exported functions as ASM_FUNC(), which puts them in a separate
section, allowing the linker to prune code that is left unused.

At the same time, clean up the code to get rid of LoadConstantToReg()
instances involving symbol references, each of which emits an absolute
literal, and hence and entry in the PE/COFF .reloc table.

ArmVirt/PrePi: make jump to CEntryPoint relative

2016-08-11T10:29:31+00:00

The ArmVirtPkg platforms that use PrePi have no notion of boot remapped
aliases, so we can simply jump to CEntryPoint() directly rather than
via an absolute reference.

ArmVirtPkg/PrePi: use correct callee saved regs

2016-08-10T11:15:15+00:00

Both the ARM and the AARCH64 versions of the PrePi code (shared between
ArmVirtQemuKernel and ArmVirtXen) 'preserve' values across a function
call using registers that are not in fact callee saved. So fix that.

ArmVirtPkg/PrePi: remove global variable allocation from lowlevel init

2015-11-27T17:06:48+00:00

Now that we dropped all ArmPlatformGlobalVariableLib dependencies,
there is no longer a need to allocate and clear out the global
variable region in the PrePi init code. So remove it.

ArmVirtPkg: use correct ASM decoration for non-function global symbols

2015-07-07T14:34:52+00:00

This fixes the declaration and definition of mSystemMemoryEnd so that it
is correctly annotated as a non-function symbol. Also adds the ASM_PFX
prefix, which is empty on AARCH64 but should be included for correctness.

ArmVirtPkg: adapt ArmVirtXen build to system memory end global variable

2015-07-06T22:09:02+00:00

This fixes the ArmVirtXen build that was broken by r17835, which adds
a global variable mSystemMemoryEnd which is shared between a module
and a library it depends on.

Add the same global variable to the relocatable PrePi used by ArmVirtXen.
