Subject: [PATCH 1023/1024] riscv: errata: Make ERRATA_STARFIVE_JH7100 depend
on !DMA_DIRECT_REMAP
Similar to the Renesas RZ/Five[1] the JH7100 SoC needs the non-portable
CONFIG_DMA_GLOBAL_POOL enabled which is incompatible with DMA_DIRECT_REMAP
selected by RISCV_ISA_ZICBOM.
[1]: commit 31b2daea0764 ("soc: renesas: Make RZ/Five depend on !DMA_DIRECT_REMAP")
Link: https://lore.kernel.org/all/24942b4d-d16a-463f-b39a-f9dfcb89d742@infradead.org/
