From: Peng Fan <peng....@nxp.com>
U-Boot device tree is padded just after U-Boot proper. After the whole
stuff loaded to DRAM space, the device tree area is conflict with BSS
region before U-Boot relocation. So any write to BSS area before
reloc_fdt will corrupt the device tree. Without the fix, there is
issue that “binman_init failed:-2” on i.MX8MP-EVK board.
Move the variable to data section to fix the issue
