PATCH v3 1/2 linux: add option to explicitly specify the kernel image name

For example the upcoming qemu-xtensa patch is using this feature, where the target is called "zImage", but the resulting kernel name is "Image.elf".

---
Changes v2 -> v3:
- improve subject (suggested by Thomas P.)
- LINUX_IMAGE_NAME defaults to LINUX_TARGET_NAME (suggested by Yann)
- improve help text (suggested by Yann)
Changes v1 -> v2:
- add comment about default value (suggested by Arnout)
- reorder default value for LINUX_TARGET_NAME (suggested by Arnout)

Thanks, I've applied this patch and the one adding the qemu xtensa defconfig. However, regarding this second one, I'd really like to see a followup patch adding a way of downloading the toolchain overlay file, instead of having it inside Buildroot.

Thanks,

Thomas

PATCH v3 1/2 linux: add option to explicitlyspecify the kernel image name : breaks kernel build !

Hi

If BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM is not set then LINUX_TARGET_NAME is undefined.

LINUX_TARGET_NAME is used on lines 266 (linux/linux.mk) and 341 to build the kernel.

Regards Johan

PATCH v3 1/2 linux: add option to explicitlyspecify the kernel image name : breaks kernel build !

Dear Sagaert Johan,

Quoted 4 lines · Sagaert Johan

If BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM is not set then LINUX_TARGET_NAME is undefined.

LINUX_TARGET_NAME is used on lines 266 (linux/linux.mk) and 341 to build the kernel.

Thanks for reporting this problem! It has been fixed in commit
http://git.buildroot.net/buildroot/commit/?id=f8f3073b18895bbf6938a5c310f6e6134f8bd6cb.
