Subject: [U-Boot] [PATCH 01/28] change_bit routine defined
Date: Wed, 14 Jul 2010 10:39:37 +0530 [thread overview]
Message-ID: <1279084204-3263-2-git-send-email-vipin.kumar@st.com> (raw)
In-Reply-To: <1279084204-3263-1-git-send-email-vipin.kumar@st.com>
From: Vipin KUMAR <vipin.kumar@st.com>
change_bit routine is left implementation dependent until now.
This routine is now defined for arm platforms in asm-arm/bitops.h
The Flexible Static memory controller driver, placed in
mtd/nand/fsmc_nand.c needs this routine. FSMC is a memory controller
peripheral from ST. The new driver implements the NAND interface part
of the peripheral.
