Commit d774442c60756a8dd5d75de85574120ce375bd72 extended struct serial_device but didn't add appropriate initialization in all serial drivers. This results in bricking a huge number of boards.

This patch adds needed initialization in serial drivers.

Reported-by: Wolfgang Denk wd@denx.de Signed-off-by: Anatolij Gustschin agust@denx.de --- This patch is based on u-boot-mpc5xxx master.

Extend mpc512x serial driver to support multiple PSC ports.

Subsequent patches for PDM360NG board support make use of this functionality by defining CONFIG_SERIAL_MULTI in the board config file. Additionally the used PSC devices are specified by defining e.g. CONFIG_SYS_PSC1, CONFIG_SYS_PSC4 and CONFIG_SYS_PSC6.

Support for PSC devices other than 1, 3, 4 and 6 is not added by this patch because these aren't used currently. In the future it can be easily added using DECLARE_PSC_SERIAL_FUNCTIONS(N) and INIT_PSC_SERIAL_STRUCTURE(N) macros in cpu/mpc512x/serial.c. Additionally you have to add code for registering added devices in serial_initialise() in common/serial.c.

Signed-off-by: Anatolij Gustschin agust@denx.de --- v3 -> v4: - rebased to apply on reworked directory structure - moved addition of the uninit() entry in serial_device to the first patch of this new series
