When building u-boot with the latest Linaro toolchain, such as gcc-linaro-4.9, u-boot will hang at PCIE init on LS1021A platform. The issue is reported on http://comments.gmane.org/gmane.linux.linaro.toolchain/5163.
As volatile is missing when reading SCTLR register and SCTLR is set according to the value read from SCTLR, it causes CR_M bit is not set. Then MMU is not enabled, the access to VA for PCIE fails.
This patch will add the missing volatile for reading SCTLR register.
