omap: sram: fix is_sram_locked check
For OMAP24xx/34xx/44xx: omap_type() returns the correct type: OMAP2_DEVICE_TYPE_TEST OMAP2_DEVICE_TYPE_EMU OMAP2_DEVICE_TYPE_SEC OMAP2_DEVICE_TYPE_GP OMAP2_DEVICE_TYPE_BAD In current implementation there are two problems: Problem 1: For 34xx, the current if check will never return true. Problem 2: For 24xx the correct type check should be with omap_type() function Verified by checking the TRM 24xx for CONTROL_STATUS register bits Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
