Subject: ARM: i.MX: initialize l2x0 at early_init time
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4bb9361def1b1af55874859d8981525ff2b6977;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ARM: i.MX: initialize l2x0 at early_init time

This can make the l2 cache work at early time which
will benefit the boot up time.

Tested on i.mx31pdk board, test result shows:

Before: arch_initcall(mxc_init_l2x0);

[    0.558755] console [ttymxc0] enabled

After: early_initcall(mxc_init_l2x0);

[    0.555716] console [ttymxc0] enabled
