This happens to be true of all our M-profile boards at the moment, but it isn't guaranteed to always be so: M-profile CPUs can be configured (via init-svtor and init-nsvtor, which match equivalent hardware configuration signals) to have the initial vector table at any address, not just zero. (For instance the Teeny board has the boot ROM at address 0x0200_0000.) Add a base address argument to armv7m_load_kernel(), so that callers now pass in both base address and size. All the current callers pass 0, so this is not a behaviour change. Signed-off-by: Peter Maydell Reviewed-by: Richard Henderson Reviewed-by: Philippe Mathieu-Daudé --- I thought about having armv7m_load_kernel() be "clever" and ask the CPU what init-svtor/init-nsvtor were set to, but that seems like it might have unanticipated consequences. "Just pass the base address" is simpler and is how A-profile does it (though for A-profile it's the loader_start field in struct arm_boot_info rather than an extra argument). --- include/hw/arm/boot.h | 5 ++++- hw/arm/armv7m.c | 5 +++-- hw/arm/aspeed.c | 1 + hw/arm/microbit.c | 2 +- hw/arm/mps2-tz.c | 2 +- hw/arm/mps2.c | 2 +- hw/arm/msf2-som.c | 2 +- hw/arm/musca.c | 3 ++- hw/arm/netduino2.c | 2 +- hw/arm/netduinoplus2.c | 2 +- hw/arm/stellaris.c | 2 +- hw/arm/stm32vldiscovery.c | 2 +- 12 files changed, 18 insertions(+), 12 deletions(-) diff --git a/include/hw/arm/boot.h b/include/hw/arm/boot.h index c7ebae156ec..f18cc3064ff 100644 --- a/include/hw/arm/boot.h +++ b/include/hw/arm/boot.h @@ -25,13 +25,16 @@ typedef enum { * armv7m_load_kernel: * @cpu: CPU * @kernel_filename: file to load + * @mem_base: base address to load image at (should be where the + * CPU expects to find its vector table on reset) * @mem_size: mem_size: maximum image size to load * * Load the guest image for an ARMv7M system.
