KS2 ddr3 initialization uses ddr3_size global variable before u-boot relocation. Even if the variable is not being used after relocation, writing to it corrupts relocation table. This patch removes the global ddr3_size variable and uses local one instead. Signed-off-by: Vitaly Andrianov <vitalya@ti.com> Tested-by: Nishanth Menon <nm@ti.com>
