8 prompt "Run U-Boot in 32/64-bit mode"
11 U-Boot can be built as a 32-bit binary which runs in 32-bit mode
12 even on 64-bit machines. In this case SPL is not used, and U-Boot
13 runs directly from the reset vector (via 16-bit start-up).
15 Alternatively it can be run as a 64-bit binary, thus requiring a
16 64-bit machine. In this case SPL runs in 32-bit mode (via 16-bit
17 start-up) then jumps to U-Boot in 64-bit mode.
19 For now, 32-bit mode is recommended, as 64-bit is still
