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 v1: Add support for J7* devices.
v1: https://lore.kernel.org/u-boot/20240131060213.1128024-1-s-k6@ti.com/T/#m19d3...
Test Results: https://gist.github.com/santhosh21/53c6f285640c4b6dfb3420d84975d12a
This series contains changes that grab the memory node from the DTS to set/modify DRAM bank sizes. A kernel patch has been sent [1] setting the required nodes to be available at bootloader stage. This patch series can be merged only after the DTS changes have been reflected in U-Boot either via OF_UPSTREAM (for devices that have moved to it) or via a sync to U-Boot patch.

Thanks and Regards, Santhosh.
