mvebu: armada 370: dts: fix the crypto engine
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.
