[OpenWrt-Devel] [PATCH 1/3] mpc85xx: revert enabling the crypto acceleration driver in the kernel

[Achim Gottinger]

Since the commit 
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=c00e5a4f09115ec976fac7dc380f576ef6a24fab 
strongswan is broken on WDR4900v1.
An bug report can be seen here: 
https://bugs.openwrt.org/index.php?do=details&task_id=1262.
To get strongswan working again i made an patch which reverts the 
changes from above commit.
According to this thread https://community.nxp.com/thread/338432 there 
is no hardware crypto extension on the  WDR4900, which explains the 
errors i get when i try to load the caamrng module. And why strongswan 
does not work.
So I assume these patches will not break anything on this router.
I also added kernel 4-14 support to mpc85xx (patch 2/3) and updated the 
crypto-hw-caam module to work with kernel versions 4.9 and 4.14 (patch 
3/3).
