Subject: [PATCH 1/4] MIPS: introduce ram0 regions register function
Date: Sat, 26 Jan 2013 20:52:37 +0400 [thread overview]
Message-ID: <1359219160-18500-2-git-send-email-antonynpavlov@gmail.com> (raw)
In-Reply-To: <1359219160-18500-1-git-send-email-antonynpavlov@gmail.com>
On MIPS there are two segments in CPU address space that
can be used for untranslated memory access: KSEG0 and KSEG1.
KSEG0 is used for cached access and KSEG1 is used for
uncached one.
The instroduced mips_add_ram0() function registers two
address regions for memory access: one in KSEG0 and
the other one in KSEG1.
