Subject: [U-Boot] PATCH-add "0X" hexadecimal prefix to simple_strtoul
Message-ID: <4D51716D.3060002@motorola.com>

Added support to simple_strtoul to support the standard 0X hex notation. This issue
was causing operational bug in U-boot console commands where "0X" hex numbers were being
misinterpreted as decimal.
