Allwinner isn't the only vendor guilty of that. Ever try finding a datasheet for any Broadcom or Qualcomm part? I'm not defending the practice. I wish all SO

Allwinner isn't the only vendor guilty of that. Ever try finding a datasheet for any Broadcom or Qualcomm part? I'm not defending the practice. I wish all SOC vendors would give full access to any/all documentation. They can still have a policy of "no support unless you sign a contract to buy X number of parts."
