Vdds_ddr decoupling caps am3358

[larbi....@gmail.com]

I see difference between last schematic of beaglebone black and am3358 starter kit board concerning vdds_ddr decoupling cap. Am3358 sk board has 21 decoupling cap and beaglebone black uses 9 decoupling caps. The am3358 datasheet specifies tu use min 20 decoupling caps. Why this difference?

BeagleBone came first. 

Smaller board size.

Lower cost

And it works.
