From 31f914c5544ba4fd4f5a4b8cfc09a7657354adcc Mon Sep 17 00:00:00 2001 From: Nina Wu Date: Thu, 21 Jan 2021 14:38:23 +0800 Subject: soc/mediatek/mt8192: devapc: Add domain remap setting MT8192 devapc supports remapping domains. There may be different domain bit for different subsys. For example, domain bit in INFRA is 4-bit, while in MMSYS, domain bit is 2-bit. For INFRA master to access MM registers, the domain bit will change from 4 to 2 and need to be remapped. In this patch we have remapped: 1. TINYSYS (3-bit to 4-bit) - domain 3 to domain 3 - others to domain 15 2. MMSYS slave (4-bit to 2-bit) - domain X to domain X, for X = 0 ~ 3 - others to domain 0 Change-Id: Id10a4c0bdf141cc76a386159896c861d0dc302aa Signed-off-by: Nina Wu Reviewed-on: https://review.coreboot.org/c/coreboot/+/49790 Tested-by: build bot (Jenkins) Reviewed-by: Yu-Ping Wu --- src/soc/mediatek/mt8192/include/soc/devapc.h | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'src/soc/mediatek/mt8192/include') diff --git a/src/soc/mediatek/mt8192/include/soc/devapc.h b/src/soc/mediatek/mt8192/include/soc/devapc.h index f227aaadd3..7ba6d46477 100644 --- a/src/soc/mediatek/mt8192/include/soc/devapc.h +++ b/src/soc/mediatek/mt8192/include/soc/devapc.h @@ -11,6 +11,10 @@ void dapc_init(void); #define DEVAPC_AO_MAX 6 enum devapc_ao_offset { + DOM_REMAP_0_0 = 0x800, + DOM_REMAP_1_0 = 0x810, + DOM_REMAP_1_1 = 0x814, + DOM_REMAP_2_0 = 0x820, MAS_DOM_0 = 0x0900, MAS_DOM_1 = 0x0904, MAS_SEC_0 = 0x0A00, @@ -48,5 +52,19 @@ enum master_domain { MAS_DOMAIN_MAX, }; +/* Domain Remap */ +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_0, 3, 0) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_1, 7, 4) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_2, 11, 8) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_3, 15, 12) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_4, 19, 16) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_5, 23, 20) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_6, 27, 24) +DEFINE_BITFIELD(FOUR_BIT_DOM_REMAP_7, 31, 28) + +DEFINE_BITFIELD(TWO_BIT_DOM_REMAP_0, 1, 0) +DEFINE_BITFIELD(TWO_BIT_DOM_REMAP_1, 3, 2) +DEFINE_BITFIELD(TWO_BIT_DOM_REMAP_2, 5, 4) +DEFINE_BITFIELD(TWO_BIT_DOM_REMAP_3, 7, 6) #endif /* SOC_MEDIATEK_MT8192_DEVAPC_H */ -- cgit v1.2.3
