2017-11-06stm32: fix STMicroelectronics copyrightPatrice Chotard
Uniformize STMicroelectronics copyrights headers for STM32 related code. Signed-off-by: Patrice Chotard <patrice.chotard@st.com>
2017-08-13armv7m: mpu_config add missing breakxypron.glpk@gmx.de
For DEVICE_NON_SHARED the newly assigned value of attr is overwritten due to a missing break. The problem was indicated by cppcheck. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2017-06-05armv7m: Fix larger buildsPhil Edworthy
The branch instruction only has an 11-bit relative target address, which is sometimes not enough. Signed-off-by: Phil Edworthy <phil.edworthy@renesas.com>
2017-05-12armv7m: add MPU configuration supportVikas Manocha
Cortex-M archs support option memory protection unit (MPU). MPU is used to set the memory types, attributes, access permissions for different regions, cache policies of the device. e.g. using MPU it is possible to configure memory region as device memory or strongly ordered, memory attributes like execute never, cache policies like write-back or write-through.

2017-05-12arvm7m: add cleanup before linux bootingVikas Manocha
Data cache memory needs to be disabled before handing over control to linux kernel. This patch populates the cleanup_before_linux stub. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>

2017-04-08armv7m: add instruction & data cache supportVikas Manocha
This patch adds armv7m instruction & data cache support. Signed-off-by: Vikas Manocha <vikas.manocha@st.com> cc: Christophe KERELLO <christophe.kerello@st.com>
2017-03-14armv7m: Add SysTick timer driverPhil Edworthy
The SysTick is a 24-bit down counter that is found on all ARM Cortex M3, M4, M7 devices and is always located at a fixed address. The number of reference clock ticks that correspond to 10ms is normally defined in the SysTick Calibration register's TENMS field. However, on some devices this is wrong, so this driver allows the clock rate to be defined using CONFIG_SYS_HZ_CLOCK.

2015-11-10arm: stm32f4: fix a bug when a random sector gets erasedVadzim Dambrouski
Old sector number is not being cleared from FLASH_CR register. For example when first erased sector was 001 and then you want to erase sector 010, sector 011 gets erased instead. This patch clears old sector number from FLASH_CR register before a new one is written. Signed-off-by: Vadzim Dambrouski <pftbest@gmail.com>
2015-11-10arm: stm32f4: fix a bug when only first sector gets erasedVadzim Dambrouski
flash_lock call is inside a for loop, so after the first iteration flash is locked and no more sectors can be erased. Move flash_lock out of the loop. Signed-off-by: Vadzim Dambrouski <pftbest@gmail.com>
2015-07-27stm32f4: add cpu clock option for 180 MHzAntonio Borneo
While most stm32f4 run at 168 MHz, stm32f429 can work till 180 MHz. Add option to select 180 MHz through macro CONFIG_SYS_CLK_FREQ.
