ARM: imx: Update DRAM timings with inline ECC on DH i.MX8MP DHCOM SoM

2023-12-16T10:45:07Z

Import DRAM timings generated by the DDR tool 3.31 which introduce assorted tweaks to the DRAM controller settings. Furthermore, enable DBI to improve noise resilience of the DRAM bus by reducing the number of bit changes on the bus. Reduce the DRAM rate to 3600 MTps to remove all remaining correctable errors reported by EDAC . It is not entirely clear why the slightly faster setting does produce sporadic correctable errors, while this one does not, but this could be related to simpler PLL setting at 3600 MTps. Enable inline ECC which is necessary to detect ECC errors and collect statistics by the EDAC driver in Linux. This reduces the DRAM size by 64 MiB for each 512 MiB of DRAM, so for a 4 GiB device the available DRAM size becomes 3.5 GiB and for 2 GiB device the available DRAM size becomes 1.8 GiB.

ARM: imx: Force DRAM regulators into FPWM mode on DH i.MX8MP DHCOM SoM

2023-12-16T10:45:02Z

In case the Buck5 and Buck6 regulators which supply DRAM Vdd1 and Vdd2/Vddq respectively operate in automatic PWM/PFM mode, the DRAM EDAC detects more correctable errors than if the regulators operate in forced PWM only mode. Force DRAM regulators to forced PWM mode only to stop tempting the DRAM. Signed-off-by: Marek Vasut

arm64: dts: imx8mp: Add DT overlay describing i.MX8MP DHCOM SoM rev.100

2023-10-16T14:25:10Z

The current imx8mp-dhcom-som.dtsi describes production rev.200 SoM, add DT overlay which reinstates rev.100 SoM description to permit prototype rev.100 SoMs to be used until they get phased out. Signed-off-by: Marek Vasut

arm64: dts: imx8mp: Switch to DT overlays for i.MX8MP DHCOM SoM

2023-10-16T14:25:10Z

Add DT overlays to support additional DH i.MX8MP DHCOM SoM 660-100 population options with 1x or 2x RMII PHY mounted on PDK2 or PDK3 carrier boards. Use SPL DTO support to apply matching SoM specific DTO to cater for the SoM differences. Remove ad-hoc patching of control DT from fdtdec_board_setup(). Signed-off-by: Marek Vasut

treewide: rework linker symbol declarations in sections header

2023-08-09T13:21:42Z

1. Convert all linker symbols to char[] type so that we can get the corresponding address by calling array name 'var' or its address '&var'. In this way, we can avoid some potential issues[1]. 2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has not been referenced by any source code. 3. Move '__data_end' to the arch x86's own sections header as it's only used by x86 arch. 4. Remove some duplicate declared linker symbols. Now we use the standard header file to declare them. [1] This patch fixes the boot failure on MIPS target.
