Subject: [PATCH 0/2] Minor fixes for CCMs
Date: Thu, 22 Dec 2016 17:09:08 +0300 [thread overview]
Message-ID: <1482415750-5471-1-git-send-email-abrodkin@synopsys.com> (raw)
It turned out current implementation of CCM support doesn't work at all.
There're 2 isseus:
* Data/code which is supposed to be in DCCM or ICCM accordingly gets
merged in common .data and .text sections so CCMs won't be used
* Kerenl will panic on early boot because comparison of CCM sizes
is implemented incorrectly
This short series fixes both issues above so CCMs are usable again.
And both patches indeed should be back-ported to stable kernels.
