Was planning to add the rule once more boards get added.

You might have missed to configure the environment u-boot variable to disable higher address space switch. 'setenv mem_lpae 0'. Also ensure to update the boot loaders since the default ones comes with EVM are long back outdated.

Also ensure to update hmm, that might do it. Will try after upgrading u-boot to latest release.

Currently, even when building keystone only kernel builds, DTB won't get build because we lack a Makefile rule to get it compiled. This patch adds that rule so mainline kernel users have a chance to use up-to-date DTB on keystone 2 platforms. Signed-off-by: Felipe Balbi <balbi@ti.com> --- note that I just tried this on top of linux-next (commit 69d5cdda16b3c9767b82d80b07edb9bb056448e3) and, even though dtb builds fine, I still couldn't get keystone_defconfig uImage to boot fine. It's probably my LOADADDR which is wrong. Santosh, what's the LOADADDR I should be using for keystone boots ? arch/arm/boot/dts/Makefile | 1 + 1 file changed, 1 insertion(+)
