The crypto engine in Armada 370 SoCs is currently broken. It can be checked installing the required packages for testing openssl with hw acceleration: opkg install openssl-util opkg install kmod-cryptodev opkg install libopenssl-devcrypto After configuring /etc/ssl/openssl.cnf to let openssl use the crypto engine for digest operations, and performing some checksums.. md5sum 10M-file.bin openssl md5 10M-file.bin ...we can see they don't match. There might be an alignment or size constraint issue caused by the idle-sram area. Use the whole crypto sram and disable the idle-sram area to fix it. Also disable the idle support by adding the broken-idle property to prevent accessing the disabled idle-sram. We don't care about disabling the idle support since it is already broken in Armada 370 causing a huge performance loss because it disables permanently the L2 cache. This was reported in the Openwrt forum and elsewhere by Debian users with different board models. Signed-off-by: Daniel González Cabanelas <dgcbueu@gmail.com>
