 272  * The TL-WDR4900 v1 uses the NXP (Freescale) P1014 SoC which is closely
 273  * related to the P1010.
 274  *
 275  * NXP QP1010FS.pdf "QorIQ P1010 and P1014 Communications Processors"
 276  * datasheet states that the P1014 does not include the accelerated crypto
 277  * module (CAAM/SEC4) which is present in the P1010.
 278  *
 279  * NXP Appliation Note AN4938 Rev. 2 implies that some P1014 may contain the
 280  * SEC4 module, but states that SoCs with System Version Register values
 281  * 0x80F10110 or 0x80F10120 do not have the security feature.
 282  *
 283  * All v1.3 TL-WDR4900 tested have SVR == 0x80F10110 which AN4938 describes
 284  * as: core rev 1.0, "P1014 (without security)".
 285  *
 286  * The SVR value is reported by uboot on the serial console.
