The original patch of this series was sent in September 2019 but unfortunately caused build problems on some boards, since they don't comply with the of-platdata rules.
With of-platdata, the idea is to compile the device tree into C structures to save space and avoid needing to use libfdt. But some boards use of-platdata while also using libfdt in a few areas, thus defeating the purpose of of-platdata.
This series includes the original two patches
http://patchwork.ozlabs.org/patch/1167420/ http://patchwork.ozlabs.org/patch/1167367/
as well as a few other patches to fix the build errors. Overall this reduces code size and provides better error messages when unavailable functions are used.
Board maintainers should still take a look at the result, adjusting the of-platdata support as needed.
Note: This series was resent a year ago but not applied. Since then, some boards have ended up using drivers in SPL which require OF_CONTROL, but SPL_OF_CONTROL is not enabled. So now we have two problems. This series fixes that one also.
The problems will keep getting worse if people are not aware that something is wrong. Therefore I think this patch series should be applied ASAP.
Changes in v6: - Add new patch for atheros - Add new patch for SPI flash - Rebase to master
Changes in v5: - Drop rockchip patches as those boards have been fixed
Changes in v4: - Add new patch for rockchip build errors - Add new patch for omap MMC build errors - Add new patch for rockchip chromebook build errors - Pull out patches into a new series - Add new patches to handle build failures
Changes in v3: - Fix eth_dev_get_mac_address() call dev_read...() only when available
Simon Glass (5): omap: mmc: Avoid using libfdt with of-platdata net: atheros: Add a check for OF_CONTROL spi: Add checks for OF_CONTROL spl: Allow SPL/TPL to use of-platdata without libfdt dm: core: Don't include ofnode functions with of-platdata
