Subject: [PATCH 1017/1024] riscv: errata: Add StarFive JH7100 errata
|
|
|
|
This not really an errata, but since the JH7100 was made before
|
|
the standard Zicbom extension it needs the DMA_GLOBAL_POOL and
|
|
RISCV_NONSTANDARD_CACHE_OPS enabled to work correctly.

|
|
+ The StarFive JH7100 was a test chip for the JH7110 and has
|
|
+ caches that are non-coherent with respect to peripheral DMAs.
|
|
+ It was designed before the Zicbom extension so needs non-standard
|
|
+ cache operations through the SiFive cache controller.
|
|
+
|
|
+ Say "Y" if you want to support the BeagleV Starlight and/or
|
|
+ StarFive VisionFive V1 boards.
