Hello,
This series is to:
Add support for Inline ECC in DDR for AM64X, AM62X, AM62AX, AM62PX, J721S2 and J784S4 devices.
(1/8) Enable ECC priming with BIST engine (2/8) Add a function to store base address and size of RAM's banks in a 64-bit device private data (3/8) Setup the ECC region start and range (4/8) Enable ECC 1-bit error, 2-bit error and multiple-bit error interrupts (5/8) Add CONFIG_K3_INLINE_ECC (6/8) Set NR_DRAM_BANKS to 2 (7/8) Pull Redundant DDR functions to a common location and Fixup DDR size when ECC is enabled (8/8) Add ss_cfg reg entry
Changes since v3: Pull redundant DDR functions to arch/arm/mach-k3/*
v3: https://lore.kernel.org/all/20240523050430.455201-1-s-k6@ti.com/
Changes since v2: Removed 'default n' in Kconfig as that is default setting
v2: https://lore.kernel.org/u-boot/20240510084707.1903133-1-s-k6@ti.com/
Changes since v1: Add support for J7* devices.
v1: https://lore.kernel.org/u-boot/20240131060213.1128024-1-s-k6@ti.com/
Test Results: https://gist.github.com/santhosh21/25937355aa2c134a64fa76480ac6a4a2
Thanks and Regards, Santhosh.
