* Revert "stm32: Change USART port to USART6 for stm32f746 discovery board"Tom Rini2016-07-21-3/+0
| | | | | | | | | | Per Vikas' request, the problem this commit is supposed to be solving is something he doesn't see and further this introduces additional hardware requirements. This reverts commit 4b2fd720a7b2f78c42d1565edf4c67f378c65440. Signed-off-by: Tom Rini <trini@konsulko.com>
* stm32: Change USART port to USART6 for stm32f746 discovery boardToshifumi NISHINAGA2016-07-14-0/+3
| | | | | | | | | | | | | This change is to remove a halt at about 200KiB while sending a large(1MiB) binary to a micro controller using USART1. USART1 is connected to a PC via an on-board ST-Link debugger that also functions as a USB-Serial converter. However, it seems to loss some data occasionally. So I changed the serial port to USART6 and connected it to the PC using an FTDI USB-Serial cable, therefore the transmission was successfully completed.

* stm32: stm32f4: move flash driver to mtd driver locationVikas Manocha2016-03-26-156/+2
| | | | | | | Same flash driver can be used by other stm32 families like stm32f7. Better place for this driver would be mtd driver location. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
* stm32: add support for stm32f7 & stm32f746 discovery boardVikas Manocha2016-02-24-0/+189

* gpio: stm32_gpio: move clock config from driver to boardVikas Manocha2016-02-24-0/+48
| | | | | | | This patch removes the gpio clock enable from gpio driver & move it in the board code, making it possible to use the gpio driver with other socs. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
* serial: serial_stm32: move clock config from driver to boardVikas Manocha2016-02-08-0/+20
| | | | | | | | This patch removes the uart clock enable from serial driver & move it in the board code. Signed-off-by: Vikas Manocha <vikas.manocha@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* stm32: move stm32 specific code to mach-stm32Vikas Manocha2016-01-20-0/+1114
This patch moves stm32 sources at one place, with this armv7m now contains only generic stuff. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
