[PATCH] arm: mach-imx: Makefile: Extend u-boot-nand.imx padding
From: Hiago De Franco Extend the padding process of u-boot-nand.imx target by adding 10k bytes of zeros to the end of the binary using the 'dd' command. The existing padding method did not generate a functional binary, as discussed in more detail in this thread [1]. Instead, we adopt the end-padding calculation method documented in 'board/doc/colibri_imx7.rst' as a reference, which is relevant for iMX7 with NAND storage. Adding 10k bytes of zeros provides an approximate value that makes the proper padding for these NAND devices.
