ARM: add debug ".edata_real" symbol

2017-11-02T00:10:28Z

Add an additional symbol to the decompressor image, which will allow future debugging of non-bootable problems similar to the one encountered with the EFI stub. Signed-off-by: Russell King

ARM: add additional table to compressed kernel

2017-10-03T12:27:07Z

Add an additional extendable table to the compressed kernel so that we can provide further information to boot loaders regarding the properties of the image contained within. This is necessary for correct behaviour of kexec. Tested-by: Tony Lindgren Tested-by: Keerthy Signed-off-by: Russell King

arm/efi: Split zImage code and data into separate PE/COFF sections

2017-08-21T07:43:51Z

To prevent unintended modifications to the kernel text (malicious or otherwise) while running the EFI stub, describe the kernel image as two separate sections: a .text section with read-execute permissions, covering .text, .rodata, .piggytext and the GOT sections (which the stub does not care about anyway), and a .data section with read-write permissions, covering .data and .bss. This relies on the firmware to actually take the section permission flags into account, but this is something that is currently being implemented in EDK2, which means we will likely start seeing it in the wild between one and two years from now.

ARM: add UEFI stub support

2015-12-14T09:38:21Z

This patch adds EFI stub support for the ARM Linux kernel. The EFI stub operates similarly to the x86 and arm64 stubs: it is a shim between the EFI firmware and the normal zImage entry point, and sets up the environment that the zImage is expecting. This includes optionally loading the initrd and device tree from the system partition based on the kernel command line.

ARM: simplify generation of compressed vmlinux.lds file

2014-07-01T14:01:51Z

As we are now using the C preprocessor, we do not need to use sed to edit constants in this file, and then pass the resulting file through the C preprocessor. Instead, rely solely on the C preprocessor to rewrite TEXT_START and BSS_ADDR. Acked-by: Nicolas Pitre Signed-off-by: Russell King
