Some omaps are producing imprecise external aborts because we are wrongly trying to init SRAM for device tree based booting. Only omap3 is still using the legacy SRAM code, so we need to make it omap3 specific. Otherwise we can get errors like this on at least dm814x: Unhandled fault: imprecise external abort (0xc06) at 0xc08b156c ... (omap_rev) from [<c08b12e0>] (omap_sram_init+0xf8/0x3e0) (omap_sram_init) from [<c08aca0c>] (omap_sdrc_init+0x10/0xb0) (omap_sdrc_init) from [<c08b581c>] (pdata_quirks_init+0x18/0x44) (pdata_quirks_init) from [<c08b5478>] (omap_generic_init+0x10/0x1c) (omap_generic_init) from [<c08a57e0>] (customize_machine+0x1c/0x40) (customize_machine) from [<c00098a4>] (do_one_initcall+0x80/0x1dc) (do_one_initcall) from [<c08a2ec4>] (kernel_init_freeable+0x218/0x2e8) (kernel_init_freeable) from [<c063a554>] (kernel_init+0x8/0xec) (kernel_init) from [<c000f890>] (ret_from_fork+0x14/0x24) Let's fix the issue by making sure omap_sdrc_init only gets called for omap3. To do that, we need to have compatible "ti,omap3" in the dts files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like we're supposed to. Signed-off-by: Tony Lindgren <tony@atomide.com>
