Title:
linaro u-boot: get_sdr_cs_offset() ignores CS1STARTLOW field
Status in Linaro U-Boot:
Fix Released
Bug description:
http://git.linaro.org/gitweb?p=boot/u-boot-linaro-
next.git;a=blob;f=arch/arm/cpu/armv7/omap3/sdrc.c;h=8905224439b5e7d07204c2b5b2b4f180c5599ce8;hb=HEAD#l94
arch/arm/cpu/armv7/omap3/sdrc.c:get_sdr_cs_offset() does this:
offset = readl(&sdrc_base->cs_cfg);
offset = (offset & 15) << 27 | (offset & 0x30) >> 17;
which is clearly shifting the offset&0x30 field off the right hand
side of the value so it is effectively ignored. Looking at the
OMAP35xx TRM (which defines bits [9:8] as CS1STARTLOW, lower address
bits a1:a0, and [3:0] as CS1STARTHIGH, upper address bits a5:a4:a3:a2)
I think that this should read "<< 17".
This doesn't have any visible effect on the h/w I have access to
(beagleboard) because CS1STARTLOW is zero anyway. I found it by code
inspection while trying to track down a different problem in qemu.
