[PATCH 09/10] commands/file: use definitions from arm/linux.h

[PATCH 03/10] make GRUB_LINUX_MAGIC_SIGNATURE architecture-specific

Rename GRUB_LINUX_MAGIC_SIGNATURE GRUB_LINUX_I386_MAGIC_SIGNATURE, to be usable in code that supports more than one image type. Signed-off-by: Leif Lindholm --- grub-core/commands/file.c| 4 ++-- grub-core/loader/i386/linux.c| 2 +-

[PATCH 08/10] arm: make linux.h safe to include for non-native builds

(for machine arm/efi) and (for machine arm/coreboot) will not always resolve (and will likely not be valid to) if pulled in when building non-native commands, such as host tools or the "file" command. So explicitly include them with their expanded pathnames. Signed-off-by: Leif Lindholm

[PATCH 01/10] arm64/efi: move EFI_PAGE definitions to efi/memory.h

The EFI page definitions and macros are generic and should not be confined to arm64 headers - so move to efi/memory.h. Also add EFI_PAGE_SIZE macro. Update loader sources to reflect new header location. Signed-off-by: Leif Lindholm --- grub-core/loader/arm64/linux.c

[PATCH 02/10] Make arch-specific linux.h include guards architecture unique

Replace uses of GRUB_LINUX_MACHINE_HEADER and GRUB_LINUX_CPU_HEADER with GRUB__LINUX_HEADER include guards to prevent issues when including more than one of them. Signed-off-by: Leif Lindholm --- include/grub/arm/linux.h | 6 +++--- include/grub/arm64/linux.h | 6

[PATCH 00/10] various cleanup

So, sorry I dropped the ball on this last year. This series contains what I would hope to be non-contentious cleanup in preparation for the functional changes (/fixes) for the arm64 linux loader and its reuse in the arm-efi port. 1/10 Simply moves the EFI_PAGE definition to . 2-7/10 Cleans

[PATCH] chainloader: patch in BPB's sectors_per_track and num_heads

These fields must reflect the ROM-BIOS's geometry for CHS-based loaders to correctly load their next stage. Most loaders do not query the ROM-BIOS (Int13.08), relying on the BPB fields to hold the correct values already. Tested with lDebug booted in qemu via grub2's FreeDOS direct loading
