2019-05-23ARM: dts: stm32mp1: DDR config v1.44Patrick Delaunay
Update DDR configuration with the latest update: - PUBL_regs: DXnGCR[0]= according to ddr_width to disable Byte lane 2/3 in 16bit - fix LPDDR2/3 timing_calc to step RL/WL in relaxed timings mode - remove LPDDR3 RL3 (optional) support vs MR0[7] because MR0[7] can't be read instead always apply worse RL/WL for LPDDR3 when freq < 166MHz) - change MR3 to 48ohm drive for LPDDR2/3 - change default ZPROG[7:4] = 0x1 for LPDDR2/3 , '0' is not allowed even when ODT not used - use DQSTRN for LPDDR2/3 (it was not set in PIR) - LPDDR3: set dqsge/dwsgx gate extension to 2,2 like LPDDR2 -DDRCTRL.dfitmg0: + for LPDDR3 tphy_wrlat = WL (as LPDDR2) + improvement for relaxed mode vs RL/Wl at corner case. For example @533MHz RL/WL (relaxed) = 9/5 for LPDDR2/3 and correction to MR2 accordingly - DDR_PCFGQOS1_1: port1 timeout relaxed from 0x00 to 0x40, for LTDC. - DDR_PCFGWQOS0_0: change vpr level from 11 to 12 in order to include the CPU on the variable priority queue. - DDR_SCHED: fix to consider 13 levels (13 levels - 1 = 0xC) Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>

2019-04-12ARM: dts: stm32: Synchronize DT with kernel onePatrice Chotard
This patch synchronizes U-boot DT with kernel one This is based on https://patchwork.kernel.org/cover/10797115/ This patch adds initial support of STM32MP157 discovery boards: - Add support of stm32mp157a discovery1 board (part number: STM32MP157A-DK1). This board embeds a STM32MP157a SOC with AC package (TFBGA361, 148 ios) and 512MB of DDR3. Several connections are available on this boards: 4*USB2.0, 1*USB2.0 typeC, SDcard, RJ45, HDMI, Arduino connector, ... - Add support of stm32mp157c discovery2 board (part number: STM32MP157C-DK2). This board is a "super-set" of stm32mp157a-dk1. A display panel (otm8009a) and Murata wifi/BT combo is added.
