Any firmware implications when changing BF537 package?

I am looking at replacing a 208 ball ADSP-BF537BBCZ-5BV with a 182 ball ADSP-BF537BBCZ-5AV.  As far as I can tell, there should be no need for any firmware changes to support the different package.  I don't see anywhere in the configuration files were you have to specify the package.  I am using uClinux and u-boot.  Can anyone confirm that?
