OMAP2/3 board-*.c files: read bootloader configuration earlier
Most board-*.c files read configuration data from the bootloader in their .init_machine() function. This needs to happen earlier, at some point before omap2_init_common_hw() is called. This is because a future patch will use the bootloader serial console port information to enable the UART clocks earlier, immediately after omap2_clk_init(). This is in turn necessary since otherwise clock tree usecounts on clocks like dpll4_m2x2_ck will be bogus, which can cause the currently-active console UART clock to be disabled during boot.
