I just want to say I am very happy to see this work happening.

I can confirm this saves 39K in the IMX8M SPL. Tested-by: Tim Harvey <tharvey@gateworks.com> #imx8mm-venice #imx8mn-venice #imx8mp-venice Best Regards, Tim
From: Peng Fan <peng.fan@nxp.com> binman symbol is a good feature, but only used on X86 for now. This patchset is to use it for i.MX8M platform. The current imx8m ddr phy firmware consumes lots of space, because we pad them to the largest 32KB and 16KB for IMEM and DMEM. With this patchset we use binman symbols to get firmware location and size, we could save near 36KB with i.MX8MP-EVK. Please help check and test Note: with this patchset, nxp downstream imx-mkimage will not work. Later patches will follow up to address.
