Re: [U-Boot] [PATCH] dm: serial: Initialize serial console only when it wasn't already configured

It may happen that the MXC serial IP block is performing some ongoing transmission (started at e.g. board_init()) when the "initr_serial" is called.

As a result the serial port IP block is reset, so transmitted data is corrupted:

I2C: ready DRAM: 1 GiB jSS('HH��SL_SDHC: 04 rev 0x0

This patch prevents from this situation, by avoiding re-initialization of serial IP block (and execution of the same code twice).

I2C: ready DRAM: 1 GiB ID: unit type 0x4 rev 0x0

This patch is a follow up of following discussions: http://patchwork.ozlabs.org/patch/820824/ http://patchwork.ozlabs.org/patch/830957/
