Arm/AARCH64 Platforms: Update AsmMacroLib.h Includes

2024-09-16T19:13:32+00:00

edk2 PR https://github.com/tianocore/edk2/pull/6048 moves AsmMacroIoLib.h and AsmMacroIoLibV8.h to MdePkg and renames them to Arm/AsmMacroLib.h and AArch64/AsmMacroLib.h, respectively. This updates all edk2-platforms in one go, as this is a breaking change and no functional change.

Platform/ARM: Fix uninitialized variable in RunAxf

2020-04-06T09:49:34+00:00

RunAxf is a shell command used for running an Axf file. The ShellDynCmdRunAxfHandler() loads an ELF file or one processed by the Flashloader. It calls the appropriate loaders to load the file in memory and to obtain the entry point address. The first argument to RunAxfPivot() is the entry point address for the image to execute. The patch https://github.com/tianocore/edk2-platforms/commit/996047695a06167a918b07b22fcd0fbd0def5da6 changes set/way cache maintenance operations to by-VA operation. This patch however introduced an error: 'variable StartElf is not initialized'. Since, StartElf is the first argument to RunAxfPivot(), which is expected to be the entry point address; RunAxfPivot() would end up branching to an invalid address resulting in a crash. Therefore, initialize StartElf to the entry point address before calling RunAxfPivot(). Signed-off-by: Sami Mujawar Reviewed-by: Ard Biesheuvel

Platform/ARM/ArmShellCmdRunAxf: switch to by-VA cache maintenance

2020-03-06T16:53:28+00:00

Currently, the 'runaxf' shell command that exists only on ARM's own development platforms deals with the caches in an unsafe manner, as it relies on set/way maintenance to ensure that the ELF image it has put into memory, as well as the running image itself is visible in memory after the MMU and caches are disabled. So let's switch to by-VA maintenance for the currently running image, as well as the ELF image, and use a helper in assembly to ensure that we are not relying on the stack between the disabling of the MMU and the invocation of the ELF image.

Platform/ARM: import BootMonFs and ArmShellCmdRunAxf from EDK2

2017-12-08T16:17:20+00:00

BootMonFs and ArmShellCmdRunAxf are only used on development boards manufactured by ARM itself, so let's keep it under Platform/ARM where it belongs. Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Ard Biesheuvel Reviewed-by: Leif Lindholm
