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
