Each register definition contains the register's offset, and for parameterized registers, the stride (distance between consecutive instances of the register). Finally, it includes an all-caps printable register name. In these files, each IPA version defines an array of IPA register definition pointers, with unsupported registers defined with a null pointer. The array is indexed by the ipa_reg_id enumerated type. At initialization time, the appropriate register definition array to use is selected based on the IPA version, and assigned to a new "regs" field in the IPA structure. Extend ipa_reg_valid() so it fails if a valid register is not defined. This patch simply puts this infrastructure in place; the next will use it.

The checks are not expensive, so just build them always. This completes the removal of all CONFIG_VALIDATE/CONFIG_VALIDATION IPA code.

All pointers used to display these attribute values (i.e., IPA pointer and endpoint pointers) will have been initialized by the time IPA probe has completed, so they may be safely dereferenced.

Starting with IPA v4.5, a few of the memory regions have a different number of "canary" values; update comments in the where the region identifers are defined to accurately reflect that. I'll note three differences in SDX55 versus the other two existing platforms (SDM845 and SC7180): - SDX55 uses a 32-bit Linux kernel - SDX55 has four interconnects rather than three - SDX55 uses IPA v4.5, which uses inline checksum offload Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.
