+ bool "Enable CN63XXP1 errata workarounds"
+ default "n"
+ help
+ The CN63XXP1 chip requires build time workarounds to
+ function reliably, select this option to enable them. These
+ workarounds will cause a slight decrease in performance on
+ non-CN63XXP1 hardware, so it is recommended to select "n"
+ unless it is known the workarounds are needed.

+ int "Number of L1 cache lines reserved for CVMSEG memory"
+ range 0 54
+ default 1
+ help
+ CVMSEG LM is a segment that accesses portions of the dcache as a
+ local memory; the larger CVMSEG is, the smaller the cache is.
+ This selects the size of CVMSEG LM, which is in cache blocks. The
+ legally range is from zero to 54 cache blocks (i.e. CVMSEG LM is
+ between zero and 6192 bytes).
