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/#m19d34d1ebc2802ad80e2412265e7858c98b0510f

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.
