This is already set up in crt0.S. We don't need a new structure and don't really want one in the 'data' section of the image, since it will be empty and crt0.S's changes will be ignored. As an interim measure, remove it only if CONFIG_DM is not defined. This allows us to press ahead with driver model in SPL and allow the stragglers to catch up. Signed-off-by: Simon Glass <sjg@chromium.org> --- Changes in v4: - Squash the gdata revert patch into this one - Allow gdata to survive unless CONFIG_DM is defined, for now Changes in v3: None Changes in v2: - Remove gdata definition from ARM spl header file also arch/arm/include/asm/spl.h | 2 ++ arch/arm/lib/spl.c | 4 ++++ 2 files changed, 6 insertions(+)
