Modify the linux kernel but not working about build

[fengyuanyu1]

@jforissier Thanks for your quick reply. It works.

1. build optee project
2. modify the source code in /linux
3. in /build, make -f qemu_v8.mk linux
4. in /build, make -f qemu_v8.mk run-only.

That's mostly good except that the linux kernel is now post-processed to produce uImage (to be loaded by U-Boot). So the "make linux" target does not do enough. Please try the following patch:

diff --git a/qemu_v8.mk b/qemu_v8.mk
index 92702e0..324f8cf 100644
--- a/qemu_v8.mk
+++ b/qemu_v8.mk
@@ -394,6 +394,8 @@ $(KERNEL_UIMAGE): u-boot linux | $(BINARIES_PATH)

...and do the following sequence instead:

1. build optee project
2. modify the source code in /linux
3. in /build, make uImage
4. in /build, make run-only.
