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

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