Re: [PATCH 65/97] ARM: l2c: prima2: convert to generic l2c initialisation

From: Barry Song <hidden>
Date: 2014-05-22 12:14:37
Also in: linux-arm-kernel

2014-04-29 3:31 GMT+08:00 Russell King [off-list ref]:
Along with this change, we can delete l2x0.c from prima2.

Signed-off-by: Russell King <rmk+kernel-lFZ/pmaqli7XmaaqVzeoHQ@public.gmane.org>
if the information you want is l2c_aux_val, l2c_aux_mask for prima2 platform.

it is (0, 0xfdffffff), you can cleary know that from the v1 i sent on
April 15, which was much earlier than your this patch:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/247423.html

and you gave many comments on that, and you read the (0, 0xFDFFFFFUL)
and disliked the upper letter.

but you just complained that i didn't provide any information to you
and you felt "frustrated".

i think that man who should fell frustrated is me not you. i feel very
frustrated for the moment.
