2019-07-12ram: stm32mp1_ram: Fix warnings when compiling with W=1Patrick Delaunay
This patch solves the following warnings: drivers/ram/stm32mp1/stm32mp1_ram.c: In function 'stm32mp1_ddr_clk_enable': warning: comparison between signed and unsigned integer expressions [-Wsign-compare] for (idx = 0; idx < ARRAY_SIZE(clkname); idx++) { ^ drivers/ram/stm32mp1/stm32mp1_ram.c: In function 'stm32mp1_ddr_setup': warning: comparison between signed and unsigned integer expressions [-Wsign-compare] for (idx = 0; idx < ARRAY_SIZE(param); idx++) { ^ Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: add tuning in DDR interactive modePatrick Delaunay
Add command tuning for DDR interactive mode, used during board bring-up or with CubeMX DDR tools to execute software tuning for the DDR configuration: - software read DQS Gating (replace the built-in one) - Bit de-skew - Eye Training or DQS training Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: add tests in DDR interactive modePatrick Delaunay
Add command tests for DDR interactive mode, used during board bring-up or with CubeMX DDR tools to verify the DDR configuration. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: add interactive mode for DDR configurationPatrick Delaunay
This debug mode is used by CubeMX DDR tuning tools or manualy for tests during board bring-up. It is simple console used to change DDR parameters and check initialization. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: add support for LPDDR2/LPDDR3Patrick Delaunay
Manage power supply configuration for board using stpmic1 with LPDDR2 or with LPDDR3: + VDD_DDR1 = 1.8V with BUCK3 (bypass if possible) + VDD_DDR2 = 1.2V with BUCK2 Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: update parameter array initializationPatrick Delaunay
Force alignment of the size of parameters array with the expected value in the binding, that allows compilation error when the array size change. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: change ddr speed to kHzPatrick Delaunay
Allow fractional support in DDR tools. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: increase the delay after reset to 128 cyclesPatrick Delaunay
Component Notification DDR controller errata (3.00a):9001313030 Synchronization Time Waited After De-assertion of presetn is 128 pclk Cycles. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-05-23stm32mp1: ram: update mask for operating modePatrick Delaunay
Regression introduced by rebase, when loop was replaced by readl_poll_timeout() function. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-04-12stm32mp1: add trusted boot with TF-APatrick Delaunay
Add support of trusted boot, using TF-A as first stage bootloader, The boot sequence is BootRom >=> TF-A.stm32 (clock & DDR) >=> U-Boot.stm32 The TF-A monitor provides secure monitor with support of SMC - proprietary to manage secure devices (BSEC for example) - PSCI for power The same device tree is used for STMicroelectronics boards with basic boot and with trusted boot.

2018-05-07regmap: change regmap_init_mem() to take ofnode instead udeviceMasahiro Yamada
Currently, regmap_init_mem() takes a udevice. This requires the node has already been associated with a device. It prevents syscon/regmap from behaving like those in Linux. Change the first argumenet to take a device node.

2018-05-07SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
