As an side question - is there an issue with defaulting to using zImage
instead of uImage for Yocto/u-boot?
No, I also think we should switch to zImage format. We only need to
update the script to call 'bootz' instead of 'bootm'.
I think this is a great idea but I believe we ought to make this for
all boards so we have it uniform across the boards; otherwise we'll
have a mix and it makes the support harder.
Considering we'd target this for 1.6, what would be the conversion plan?
Who could be responsible for each board for converting/testing?
Not sure, my thought was to leave it to the board maintainers. Unless I'm
mistaken (which is a possibility), for some reason uImage does not work when
booting with the 3.10.X kernels. It that is the case then we either need to
figure out the problem with uImages or others will be forced to use zImage anyway.
Here are the steps I've considered:
A) Send two patches to meta-freescale for meta-fsl-arm-extra to make the
conversion:
1) bbappend for u-boot to patch the include/configs/<board>.h file to use
and boot from zImage
2) Patch conf/machine/include/<board>.inc to set KERNEL_IMAGETYPE to zImage
B) Test the current stable kernels with these settings
c) Upstream the U-boot patch to u-boot-imx
