Source code for bootloader?

I'm inspecting the bootloader app in OMAPL138_StarterWare_1_10_04_01. There's no CCS project for the EVMOMAPL137, so I'm looking at the one for lcdkOMAPL138.  Browsing through the code, there's no source for either of these functions, just library for them:

    /* Spi Initialization */
    BlPlatformSPISetup();
    BlSPIConfigure();

Is it available?  If so, could you post?

Thanks.
