From 7a4b6964b54d5067181db803f68c7472a9d07efa Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Tue, 21 Apr 2020 09:28:47 +0200 Subject: mips: mtmips: add SPL support This patch adds SPL support for mtmips platform. The lowlevel architecture is split into SPL and the rest parts are built into a memory loadable u-boot image. Optional SPL_DM and OF_CONTROL are also supported. The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are not enabled and the memory bootable u-boot (u-boot.img) is generated automatically so there is not need to add a separate config for it. A lzma compressed payload (u-boot-lzma.img) is also generated and it will be combined with u-boot-spl.bin to form the unified ROM bootable binary u-boot-mtmips.bin. A spl loader is added to support uncompress the payload.
