o Disable interrupts while not running U-Boot code. We clobber registers that the U-Boot interrupt handlers assume to be fixed as per the U-Boot register usage. At this time this only applies to r14. U-Boot uses r2 now for what they used r29 for. After we restore r14 in preparation of doing the syscall, we re-enable interrupts. When we return from the syscall, we disable interrupts and restore the callee-saved r14. |
