The TI vendor kernel's dma-heap.h carries DMA_HEAP_IOCTL_EXPORT in

have the custom changes.Copy it straight from the kernel's staged
source tree (STAGING_KERNEL_DIR) into a separate /usr/include/ti/linux
path instead, for userspace code that needs it.

Why do you need this dependency for do_configure? Moreover, since you don't
have do_configure nor do_compile, you might want to mark them as "noexec"
Thanks for catching this, will fix in v4. do_install() is where the
vendor tree dependency needs to be,not in do_configure(),will drop it
and mark it as a noexec.I see the cpsw9g-eth-fw_git.bb uses the same
method.
+do_install[depends] += "virtual/kernel:do_shared_workdir"
How do you ensure that virtual/kernel is the TI vendor kernel? If it's not,
you'll be copying the original unmodified header into the ti/linux location.
okay so virtual/kernel can resolve to linux-ti-mainline or linux-bb.org
or anything set by BSP_KERNEL_PROVIDER defined in per machine conf ? I
don't have a complete understanding of how these are organized in our
Yocto project layers. Let me check how to restrict to only the TI vendor
kernel where this header file change is patched.
Regards,
Hari
