- /* Store the boot device in omap4_boot_device */
- ldr r2, [r0, #BOOT_DEVICE_OFFSET] @ r1<- value of boot device
- and r2, #BOOT_DEVICE_MASK
- ldr r3, =omap4_boot_device
- str r2, [r3] @ omap4_boot_device<- r1
Why don't you use stadard global data here?
SPL has access to .data right from the beginning. Besides this is too early. global data is not initialized yet.
Please keep in mind that this is a special situation then. The code will not work as intended for example when running form NOR flash.
Best regards,
