Subject: ARM: l2c: prima2: remove cache size override
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c95680e6f56d6bc345a7907c4d4bd985e875f2a7;p=linux-beck.git

ARM: l2c: prima2: remove cache size override

The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP.  Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to
the L2 cache code.  Remove them so we can find out which really need
this.
