2022-03-10ram: aspeed: Rework kconfig optionsJoel Stanley
Ensure the ASPEED related options are grouped together under the RAM option when enabling support. This also makes some minor grammar corrections and renames options so they present cleanly in menuconfig. There should be no functional change to the configuration or binary.

Multiple DDR subsystems In Multi DDR subystems with interleaving support, the following needs to configured, - interleaving granular size and region - EMIFs to be enabled - EMIFs with ecc to be enabled - EMIF separated or interleaved - number of cycles of unsuccessful EMIF arbitration to wait before arbitrating for a different EMIF port, by default set to 3 Add support for configuring all the above by using a MSMC device Signed-off-by: Aswath Govindraju <[email protected]>

2021-11-30ram: stm32mp1: compute DDR size from DDRCTL registersPatrick Delaunay
Compute the DDR size from DDR controller register (mstr and addrmap) in U-Boot proper as the DDR information are useful only for SPL but not for U-Boot proper, for example with TFABOOT. This patch simplify U-Boot DT when several DDR size are supported and support of next SOC in STM32MP family.

2021-11-30stm32mp1: ram: remove tuning supportPatrick Delaunay
Remove the DDR interactive command tuning, as the support of a predefined DDR PHY tuning is removed for STM32MP1 driver in SPL and in TF-A and the result of this tuning will be never used. Moreover this SW tuning procedure can failed on some hardware configuration (to many BIST errors and no convergence); it will be no more supported in the next delivery of the DDR utilities included in the CubeMX tool of STMicroelectronics.

2021-11-30stm32mp1: ram: remove the support of calibration resultPatrick Delaunay
The support of a predefined DDR PHY tuning result is removed for STM32MP1 driver because it is not needed at the supported frequency when built-in calibration is executed. The calibration parameters were provided in the device tree by the optional node "st,phy-cal", activated in ddr helper file by the compilation flag DDR_PHY_CAL_SKIP and filled with values generated by the CubeMX DDR utilities. This patch - updates the binding file to remove "st,phy-cal" support - updates the device trees and remove the associated defines - simplifies the STM32MP1 DDR driver and remove the support of the optional parameter "st,phy-cal" After this patch, the built-in calibration is always executed and the calibration registers are moved in the phy dynamic part; that allows manual tests.

Add the read data eye training = training for optimal read valid placement (RVTRN) when the built-in calibration is executed for LPDDR2 and LPDDR3. This training is supported on the PUBL integrated in the STM32MP15x DDR subsystem and it is not required for DDR3.

2021-11-10stm32mp15: replace CONFIG_TFABOOT when it is possiblePatrick Delaunay
In some part of STM32MP15 support the CONFIG_TFABOOT can be replaced by other config: CONFIG_ARMV7_PSCI and CONFIG_ARM_SMCCC. This patch also simplifies the code in cpu.c, stm32mp1_ram.c and clk_stml32mp1.c as execution of U-Boot in sysram (boot without SPL and without TFA) is not supported: the associated initialization code is present only in SPL. This cleanup patch is a preliminary step to support SPL load of OP-TEE in secure world, with SPL in secure world and U-Boot in no-secure world.
