Chance since v4: PATCH 14/14 new patch, add documentation about aarch64 qemu virt Change since v3: PATCH 2/14 remove hunk belonging to PATCH 3/14 PATCH 3/14 create a lib/ for common code and lib32/ lib64/ PATCH 4/14 add setupc_64, for now setup_c() only memset bss PATCH 12/14 use default memory layout, chance TEXT_BASE address to let malloc space below Change since v2: PATCH 1/14 add PHYS_ADDR_T_64BIT config PATCH 3/14 remove modules.c and clean atags functions in armlinux.c, and fix also parameters passed to linux kernel. PATCH 12/14 move lowlevel file from mach-qemu/ to boards/ (like others boards) split dram and flash init increase dram/flash size PATCH 13/14 new patch, in case of armv8, swab need to be done on 32-bit wide register otherwise swapping the value: "0xAAAABBBB" will become "0xAAAABBBB00000000" and see as a null value in uint32_t variable. PATCH 14/14 new patch, add define to handle arm64 uimage format Change since v1: PATCH 2/12: remove hunk which belongs to patch adding mach-qemu PATCH 3/12: remove unused files PATCH 4/12: create lowlevel64 PATCH 11/12: create pgtables64 (nothing in common with the arm32 version) PATCH 12/12: rename "mach-virt" => "mach-qemu" rename board "qemu_virt64" remove board env files Hello, This patch series introduces a basic support for arm64. The arm64 code is merged in the current arch/arm directory. I try to be iterative in the merge process, and find correct solutions to handle both architecture at some places. I test the patch series by compiling arm64 virt machine and arm32 vexpress-a9 and test it in qemu, everything seems to work.
