From: Rasmus Villemoes Date: Mon, 20 Jun 2022 08:53:20 +0000 (+0200) Subject: imx8: use ROM API wrappers in spl_imx_romapi.c X-Git-Url: http://git.dujemihanovic.xyz/repo?a=commitdiff_plain;h=f8001fdd2ca79712b5d1d5202f29d4ee1110f420;p=u-boot.git imx8: use ROM API wrappers in spl_imx_romapi.c Simplify the use of the ROM API by using the wrappers that take care of saving/restoring gd and computing the xor value. This makes the generated code smaller and the C code easier to read.
