[PATCH v4 0/8] Inline ECC Series

[Santhosh Kumar K]

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/

Thanks and Regards,
Santhosh.
