2020-07-28Revert "ARM: dts: stm32: Reinstate card detect behavior on ST boards"Patrick Delaunay
Since commit f13ff88b61c3 ("gpio: stm32: add ops set_dir_flags") the gpio flags are supported by stm32 pinctrl driver. The cd-gpios is correctly handle in U-Boot and the patch on the device tree can be removed. This reverts commit 792919241b3d750cd5295dfe6dd1d0958b9be468.

2020-07-28stm32mp1: use a specific SD/eMMC partition for U-Boot enviromnentPatrick Delaunay
Save the environment at the end of the U-Boot partition, the GPT partition named "ssbl" in SD card or eMMC and avoid requirements on the "bootfs" file system generated via specific raw tools (like wic and genimage). With the previous configuration of the U-Boot environment saved in ext4 file, U-Boot need to create/modify the file uenv.txt in the ext4 file system; so this EXT4 file system need to be generated without some functionality, like metadata_csum and dir_index, because they are not supported by U-Boot.

This patch allows to switch the CPU frequency to 800MHz on the ST Microelectronics board (DK1/DK2 and EV1) or dh electronics SOM using the STM32MP15x SOC and when it is supported by the HW (for STM32MP15xD and STM32MP15xF).

2020-06-19ARM: dts: stm32: Reinstate card detect behavior on ST boardsPatrick Delaunay
The cd-gpios with (GPIO_ACTIVE_LOW | GPIO_PULL_UP) gpio is thus far unsupported, reinstate the old cd-gpios behavior until this handling is fully implemented. This avoid potential issue for SDCard boot: the card detect fails with floating gpio. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
2020-06-16dts: ARM: stm32mp15: add OP-TEE node in u-boot DTSIEtienne Carriere
Add OP-TEE firmware node in stm32mp15 U-Boot DTSI. This node is needed since commit [1] that changed U-Boot/stm32mp15 to detect OP-TEE availability by probing the resource instead of relying on U-Boot configuration. The software sequence implemented by [1] is fine but U-Boot DTS/DTSI files were not updated accordingly since, hence OP-TEE presence is never detected by U-Boot, preventing Linux kernel from using OP-TEE resources. For consistency and to synchronize stm32mp15 DTSI files (excluding U-Boot specific DTSI files) with the Linux kernel ones, this change also moves the OP-TEE reserved memory nodes from board generic DTSI files to U-Boot specific board DTSI files.

2020-03-24ARM: dts: stm32mp1: DT alignment with Linux 5.6-rc1Patrick Delaunay
This commit manages diversity for STM32M15x SOCs with: - dedicated files to support all STM32MP15 SOCs family. The differences between those SOCs are: -STM32MP151 [1]: common file. -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU. -STM32MP157 [3]: STM32MP153 + DSI + GPU. - new files to manage security diversity on STM32MP15x SOCs. On STM32MP15xY, "Y" gives information: -Y = A means no cryp IP and no secure boot. -Y = C means cryp IP + secure boot. - stm32mp157 pinctrl files to better manage package diversity.

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>
2018-04-06stm32mp1: change STGEN clock source to HSEPatrick Delaunay
No more use static frequency HSI = 64MHz for STGEN clock but HSE (with higher accurency) by default. Need to remove CONFIG_SYS_HZ_CLOCK as arch timer frequency is provided at boot by BootRom and cp15 cntfrq and modified during clock tree initialization if needed. When HSI is no more used by any device, this internal oscillator can be switched off to reduce consumption. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
