board_r: workaround deleted output line and garbage charsColibri_iMX7_LinuxImageV2.7Beta1_20170112Colibri_iMX6_LinuxImageV2.7Beta1_20170112Colibri_VF_LinuxImageV2.7Beta1_20170112Colibri_T30_LinuxImageV2.7Beta1_20170112Colibri_T20_LinuxImageV2.7Beta1_20170112Apalis_iMX6_LinuxImageV2.7Beta1_20170112Apalis_TK1_LinuxImageV2.7Beta1_20170112Apalis_T30_LinuxImageV2.7Beta1_20170112
When booting we see:
DRAM: 256 MiB
<strange characters>FSL_SDHC: 0, FSL_SDHC: 1
auto-detected panel vga-rgb
The should be:
DRAM: 256 MiB
PMIC: device id: 0x10, revision id: 0x11, programmed
MMC: FSL_SDHC: 0, FSL_SDHC: 1
auto-detected panel vga-rgb
This seems to be caused by the call to initr_serial which
in our configuration goes into drivers/serial/serial-uclass.c
serial_initialize().
Printing an empty line helps. The empty line gets deleted and
no strange characters appear.
