From 7ef5b1e7ed040683ff551f0234c471ce0d76828c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 20 Jul 2018 21:47:18 +0900 Subject: [PATCH] ARM: uniphier: enable distro boot Switch to the distro boot for UniPhier platform. - Remove the environment vairalbes used to load images from raw block devices. - Keep the command to download images via tftp. This will be useful to boot the kernel when no valid kernel image is ready yet in the file system. - Use root.cpio.gz instead of root.cpio.uboot because we always know the file size of the init ramdisk; it is loaded via either a file system or network. - Rename fit_addr_r to kernel_addr_r, which the distro command checks to get the load address of FIT image.
