Nit: That's wrapped really narrow. Any chance of wrapping to more like 
72-74 characters?

Conceptually this change looks fine. Rather than using nested ifs, why 
not write "if a and b:" and so avoid adding an extra indent level? I'd 
also introduce some variables to shorten the text a bit:

bcfg = u_boot_console.config.buildconfig
if bcfg.get('config_spl', 'n') == 'y' and
         bcfg.get('config_spl_serial_support', 'n') == 'y':
     ...

or:

bcfg = u_boot_console.config.buildconfig
config_spl = bcfg.get('config_spl', 'n') == 'y'
config_spl_serial_support = bcfg.get('config_spl_serial_support',
     'n') == 'y'
if config_spl and config_spl_serial_support:
     ...
