| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this delay, write/read is failing. Looks like, the WIP always remain set and hence a timeout occurs leading to the error. Without this patch, device does not get probed also. Here is the log.

* | arc: fix relocation for big-endian targetAlexey Brodkin2014-02-21-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of little-endian ARC700 instructions (which may include target address) are encoded as middle-endian. That's why it's required to swap bytes after read and ten right before write back. But in case of big-endian ARC700 instructions are encoded as a plain big-endian. Thus no need for byte swapping.

* | serial/serial_arc: switch from {read|write}l to {read|write}b accessorsAlexey Brodkin2014-02-21-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This is required for proper functionality on big-endian targets. Memory-mapped registres of ARC UART are not 32-bit words but 8-bit bytes so on little-endian target either acessor (_l or _b) works fine. On big-endian only _b accessors works as expected.
