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"


+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.


Should this just be part of the linux-ti-staging recipes? That way we can correctly only include it in the versions that have this file?
