* stm32: Explicitly reset peripheral clocks on stm32f1Kevin O'Connor2020-03-241-0/+5

* stm32: Revert "stm32: performance improvement for spi on stm32f0"Kevin O'Connor2020-03-041-8/+4
| | | | | | | | | | | This reverts commit a2c309a2b02d16ec15fee5702463621239261266. The above commit is causing crashes on the stm32f103xb chip when spi is in use. It's unclear what the cause of the regression is, but the optimization isn't required so revert it until the root cause can be determined. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Fix broken clock setup on stm32f1Kevin O'Connor2020-02-291-2/+2
| | | | | | | | | Commit bd6c25c9 introduced a typo that caused the clock divisors to not be set correctly on stm32f1. Reported by @brianrjones69. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: The stm32f1 can only reach 64Mhz when using an internal clockKevin O'Connor2020-02-141-0/+1

* stm32: Increase adc sample timeKevin O'Connor2020-01-251-4/+4
| | | | | | | Increase the sample time register from 3 to 4 (which adds about ~1.5us to each adc sample). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Only declare alternate usart2 on stm32f0Kevin O'Connor2020-01-233-49/+41
| | | | | | | Also, try to improve the structure of the #if/#else/#endif layout in serial.c. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: add alternate pinout for USART2Arne Jansen2020-01-233-1/+16
| | | | | | Added to both generic stm32 and stm32f0 Signed-off-by: Arne Jansen <arne@die-jansens.de>
* stm32: add alternate pinouts for spi1/2Arne Jansen2020-01-231-3/+9
| | | | | | | In addition to spi3, spi1 and spi2 also have alternate pins. Add them as spi1a and spi2a, similar to spi3. Signed-off-by: Arne Jansen <arne@die-jansens.de>
* stm32: performance improvement for spi on stm32f0Arne Jansen2020-01-231-4/+8
| | | | | | | | | | The stm32 has a small queue for spi tx/rx. The current code only uses the spi with a single byte buffer, effectively waiting for each byte to complete before starting the next transfer. This patch changes the structure of spi_transfer() to make use of the queue and achieve back-to-back transfer of bytes on spi. Signed-off-by: Arne Jansen <arne@die-jansens.de>
* stm32: fix spi_transfer for stm32f0Arne Jansen2020-01-231-2/+8
| | | | | | | | | | The current code accesses the DR as 32 bit. This enabled data packing mode, effectively adding a 00 byte between each sent byte. The receive side had similar problems. To prevent this, all accesses are 8 bit now, even though this is not necessary on stmf[14]. Signed-off-by: Arne Jansen <arne@die-jansens.de>

* stm32: Implement armcm_main() in arch specific codeKevin O'Connor2019-10-246-30/+40
| | | | | | | Move armcm_main() to stm32f0.c, stm32f1.c, and stm32f4.c. This gives the arch specific code more control on the early boot setup. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* armcm_boot: Use armcm_main() instead of main() to start board codeKevin O'Connor2019-10-241-5/+5
| | | | | | | | | | The main() function has a special meaning to gcc and using it can result in different code generation. Use armcm_main() to avoid that. Also, invoke SystemInit() from the board specific armcm_main() code. This gives the board code more control over board initialization. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
