U-Boot README recommends initializing SDRAM in board_init_f(). DA850 was doing it as part of board_init_r() (through call to spl_board_init() which calls arch_cpu_init() which calls da850_ddr_setup())
This worked fine till commit 15b8c7505819 ("davinci: da850evm/omapl138-lcdk: Move BSS to SDRAM because SRAM is full") moved BSS to SDRAM.
Functions like mmc_initialize() called in board_init_r() assume BSS is available. Since SDRAM was not initialized when arch/arm/lib/crt0.S tried to initialize BSS to 0, BSS is not initialized correctly.
Fix this by simply calling arch_cpu_init() from board_init_f(). Also move preloader_console_init() there to help debug issues with board_init_r().
With this spl_board_init() is no longer needed, we remove it.
Tested using MMC/SD boot on OMAP-L138 LCDK board.
