Smp8634 certificate stuff
From t-hack.com - Hack X300T / X301T
The 8 bit CertificateType undicates the certificate type
Cert Types
0: cpuBootloader(zboot), cpuzone 1: cpucode, cpuzone, used to sign cpukernels and applications 2: xtask1, xpuzone, used to develop and release SDK DRM implementations 3: video microcode, protected risczone, used by Sigma Designs only 4: audio microcode, protected risczone, used by Sigma Designs only 5: transport demuxmicrocode, protected risczone, used by Sigma only 6: irqhandler running on xpu, xpuzone, used by Sigma Designs only 7: xtask2, xpuzone, used for Sigma Designs DRM implementations. 8: xtask3, xpuzone 9: xtask4, xpuzone 0xff: xosupdate
The Certificate 0< ID < 2048 is a ID which uniquely identifies each Certificate issued by Sigma Designs
