Subject: [PATCH] riscv: errata: Make ERRATA_STARFIVE_JH7100 depend on !DMA_DIRECT_REMAP
Date: Fri, 15 Dec 2023 20:09:09 +0100 [thread overview]
Message-ID: <20231215190909.3722757-1-emil.renner.berthing@canonical.com> (raw)
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/
Fixes: 64fc984a8a54 ("riscv: errata: Add StarFive JH7100 errata")
