[U-Boot] [PATCH v2] MX51: mx51evk: Use struct to access SRSR register instead of offset

Use struct to access SRSR register instead of offset. While at it mask the 7 bits of SRSR for correctness.
Signed-off-by: Fabio Estevam fabio.estevam@freescale.com --- Changes since v1: - Use readl to read the srsr register - Mask the lower 7 bits of the SRSR register for getting the correct result.

Hi Fabio,
Use struct to access SRSR register instead of offset. While at it mask the 7 bits of SRSR for correctness.

The SRSR is a MX51 register and thus not board specific. Can we please move this reset cause detection into common mx51 code so other boards will profit from it also?
Thanks Detlev
