Wire up the BLOB-free TPL DRAM init for RK3576: Kconfig (arch/arm/mach-rockchip/Kconfig): Add 11 imply lines to ROCKCHIP_RK3576 to pull in the necessary TPL subsystems: TPL_CLK, TPL_DM, TPL_OF_CONTROL, TPL_OF_PLATDATA, TPL_RAM, TPL_REGMAP, TPL_ROCKCHIP_COMMON_BOARD, TPL_SERIAL, TPL_SYSCON, TPL_TINY_MEMSET, ROCKCHIP_SDRAM_COMMON.
Kconfig (arch/arm/mach-rockchip/rk3576/Kconfig): Set TPL_TEXT_BASE = 0x3ff82000. This is the start of the SRAM region available for TPL between the boost stub (0x3ff81000) and the SPL load address (0x3ffc0000), giving ~248 KB. Kconfig (drivers/ram/rockchip/Kconfig): Add RAM_ROCKCHIP_LPDDR5 config option, required for RK3576 boards with LPDDR5 memory. defconfig (configs/sige5-rk3576_defconfig): - Disable ROCKCHIP_EXTERNAL_TPL (use our open-source TPL instead) - Enable CONFIG_TPL=y - Enable CONFIG_RAM_ROCKCHIP_LPDDR5=y for the Sige5 board Signed-off-by: Johan Axelsson <[email protected]> --- arch/arm/mach-rockchip/Kconfig | 11 +++++++++++ arch/arm/mach-rockchip/rk3576/Kconfig | 3 +++ configs/sige5-rk3576_defconfig | 3 +++ drivers/ram/rockchip/Kconfig | 7 +++++++ 4 files changed, 24 insertions(+) diff --git a/arch/arm/mach-rockchip/Kconfig b/arch/arm/mach-rockchip/Kconfig index 108713488af..3f76bf7a92a 100644 --- a/arch/arm/mach-rockchip/Kconfig +++ b/arch/arm/mach-rockchip/Kconfig @@ -488,6 +488,17 @@ config ROCKCHIP_RK3576 imply SPL_REGMAP imply SPL_SERIAL imply SPL_SYSCON + imply ROCKCHIP_SDRAM_COMMON + imply TPL_CLK + imply TPL_DM + imply TPL_OF_CONTROL + imply TPL_OF_PLATDATA + imply TPL_RAM + imply TPL_REGMAP + imply TPL_ROCKCHIP_COMMON_BOARD + imply TPL_SERIAL + imply TPL_SYSCON + imply TPL_TINY_MEMSET imply ENV_RELOC_GD_ENV_ADDR imply SYSRESET help diff --git a/arch/arm/mach-rockchip/rk3576/Kconfig b/arch/arm/mach-rockchip/rk3576/Kconfig index f347caf8904..58f1eb9fcd6 100644 --- a/arch/arm/mach-rockchip/rk3576/Kconfig +++ b/arch/arm/mach-rockchip/rk3576/Kconfig @@ -1,5 +1,8 @@ if ROCKCHIP_RK3576 +config TPL_TEXT_BASE + default 0x3ff82000 + config TARGET_ROC_PC_RK3576 bool "Firefly ROC-RK3576-PC" help diff --git a/configs/sige5-rk3576_defconfig b/configs/sige5-rk3576_defconfig index be46f63798b..38148ccab09 100644 --- a/configs/sige5-rk3576_defconfig +++ b/configs/sige5-rk3576_defconfig @@ -4,6 +4,9 @@ CONFIG_COUNTER_FREQUENCY=24000000 CONFIG_ARCH_ROCKCHIP=y CONFIG_DEFAULT_DEVICE_TREE="rockchip/rk3576-armsom-sige5" CONFIG_ROCKCHIP_RK3576=y +# CONFIG_ROCKCHIP_EXTERNAL_TPL is not set +CONFIG_TPL=y +CONFIG_RAM_ROCKCHIP_LPDDR5=y CONFIG_SYS_LOAD_ADDR=0x40c00800 CONFIG_DEBUG_UART_BASE=0x2AD40000 CONFIG_DEBUG_UART_CLOCK=24000000 diff --git a/drivers/ram/rockchip/Kconfig b/drivers/ram/rockchip/Kconfig index d707d09c1c8..51740ed1d12 100644 --- a/drivers/ram/rockchip/Kconfig +++ b/drivers/ram/rockchip/Kconfig @@ -48,4 +48,11 @@ config RAM_ROCKCHIP_LPDDR4 This enables LPDDR4 sdram code support for the platforms based on Rockchip SoCs. +config RAM_ROCKCHIP_LPDDR5 + bool "LPDDR5 support for Rockchip SoCs" + help + This enables LPDDR5 sdram code support for the platforms based + on Rockchip SoCs.
