This leads to failures to build such as: +(neu6a-io-rk3588) drivers/core/ofnode.c: In function 'ofnode_to_fdt': +(neu6a-io-rk3588) drivers/core/ofnode.c:176:21: error: assignment discards 'const' qualifie from pointer target type [-Werror=discarded-qualifiers] +(neu6a-io-rk3588) 176 | fdt = gd->fdt_blob; +(neu6a-io-rk3588) | ^ +(neu6a-io-rk3588) cc1: all warnings being treated as errors -- Tom
