Subject: [U-Boot] [PATCH] mx6: Avoid writing to read-only bits in imximage.cfg
Date: Tue, 12 Jun 2012 20:20:33 +0530	[thread overview]
Message-ID: <4FD75739.90007@gmail.com> (raw)

If in case this is valid according to the latest datasheet, ignore this patch.

According to REV C manual, the register IOMUXC_IOMUXC_GPR4 has
bits 4 and 5 read-only and the value is always set as zero.
So write '0' to these bits instead of writing '1'.
