This commit is necessary to be able to re-use the pinctrl code in early SPL to properly configure pins. The problem is that those "static" structures (without explicit initialization) are placed in the SDRAM area, which corresponds to u-boot proper (not even SPL). Hence, when one wants to configure pins before relocation via DTS/DM, the board hangs (imx6q SoC powered one) as only OCRAM area is available (0x009xxxxx). This commit prevents from this issue by moving the imx6_pinctrl_soc_info structure to data section (from BSS). Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Peng Fan <peng.fan@nxp.com>
