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.

2021-11-30stm32mp1: ram: add read valid training supportPatrick Delaunay
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.

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <[email protected]>

The SRAM on the PX30 is not big enough to hold multiple DDR configs so it needs to be selected during build. So far simply the DDR3 config was always selected and getting DDR4 or LPDDR2/3 initialized would require a code modification. So add Kconfig options similar to RK3399 to allow selecting the DDR4 and LPDDR2/3 options instead, while DDR3 stays the default as before.
