From 09739f8ba5f4f6e4d7a4c3312a8471c06e99a8f1 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens <hauke@hauke-m.de> Date: Mon, 18 Aug 2014 21:00:55 +0000 Subject: [PATCH] brcm47xx: image: build alternative TRX using less optimized LZMA MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is a group of devices that lzma-loader doesn't work with. They simply hang at "Starting program at 0x80001000" which is really hard to debug and we didn't find any solution for this for years. Broadcom doesn't use lzma-loader on these devices anyway. They decided to drop lzma-loader and use less optimal LZMA compression that can be handled by CFE itself (it doesn't use dictionary). So support these devices we will need kernel compressed with different parameters and trx without a loader.
