From 7aa5b5ece9c1800f18d7f4404b77a62ee9278b8f Mon Sep 17 00:00:00 2001 From: Yu-Ping Wu Date: Thu, 4 Feb 2021 16:24:21 +0800 Subject: soc/mediatek/mt8192: Use LZ4 compression for MCUs For MT8192 MCUs, replace LZMA compression with LZ4 to speed up boot process. The loading (plus decompression) time of mcupm.bin and sspm.bin is consistently reduced by 8ms, respectively.
