From: iuncuim <iunc...@gmail.com> At the moment, the driver only supports DDR3 and LPDDR3 memory. Add support for a new type DRAM. These changes have been successfully tested by me with orangepi zero3 4GB (DRAM: Rayson RS1G32LO4D2BDS-53BT). This patch should be applied after this: https://lore.kernel.org/all/20231014170236.16211-1-andre.przyw...@arm.com/
Changes from v3: * added LPDDR4 part for mctl_phy_read_training() * added the new part in mctl_phy_configure_odt() as LPDDR4 specific to avoid possible problems with existing devices https://lore.kernel.org/u-boot/20231104062248.32938-1-iunc...@gmail.com/ Changes from v2: * added default value for TPR6 parameter * added panic for unsupported DRAM types in switch/case conditions * added new line at the end of the timings file, changed the description * added a few small missing parts obtained from boot0 https://lore.kernel.org/u-boot/20231016053441.3197087-2-iunc...@gmail.com/ Changes from v1: * replaced the phy_init array with one compatible with opizero3 * added DRAM TPR6 parameter * adaptation to new mctl_phy_configure_odt() * added timings for the board orangepi zero3 4GB https://lore.kernel.org/u-boot/20230729111331.173768-2-iunc...@gmail.com/ Signed-off-by: Mikhail Kalashnikov <iunc...@gmail.com> iuncuim (1): sunxi: H616: add LPDDR4 support .../include/asm/arch-sunxi/dram_sun50i_h616.h | 2 + arch/arm/mach-sunxi/Kconfig | 17 ++ arch/arm/mach-sunxi/dram_sun50i_h616.c | 218 ++++++++++++++---- arch/arm/mach-sunxi/dram_timings/Makefile | 1 + .../dram_timings/h616_lpddr4_2133.c | 95 ++++++++ 5 files changed, 294 insertions(+), 39 deletions(-) create mode 100644 arch/arm/mach-sunxi/dram_timings/h616_lpddr4_2133.c -- 2.42.0
