Hello,
This series is to:
Add support for Inline ECC in DDR for AM64X, AM62X, AM62AX, AM62PX,
J721S2 and J784S4 devices.
(1/9) Add ss_cfg reg entry
(2/9) Enable ECC priming with BIST engine
(3/9) Add a function to store base address and size of RAM's banks
in a 64-bit device private data
(4/9) Setup the ECC region start and range
(5/9) Enable ECC 1-bit error, 2-bit error and multiple-bit
error interrupts
(6/9) Add CONFIG_K3_INLINE_ECC
(7/9) Remove 'ti,ecc-enable' flag
(8/9) Set default NR_DRAM_BANKS to 2
(9/9) Pull Redundant DDR functions to a common location and Fixup
DDR size when ECC is enabled
Changes since v4:
1. Make dram_init and dram_init_banksize weak at mach-k3/ and define at
board/ti/
2. Remove 'ti,ecc-enable' flag
3. Minor changes like patch order change (8/8 in v4 to 1/9 in v5),
use 'u64'
v4: https://lore.kernel.org/u-boot/20241021044024.835846-1-s...@ti.com/
Changes since v3:
Pull redundant DDR functions to arch/arm/mach-k3/*
v3: https://lore.kernel.org/all/20240523050430.455201-1-s...@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...@ti.com/
Changes since v1:
Add support for J7* devices.
v1: https://lore.kernel.org/u-boot/20240131060213.1128024-1-s...@ti.com/
