* stm32: Add 16KiB bootloader option for STM32F103 (#4493)Simon Hawkenson2021-07-151-1/+1
| | | | | The Eryone ER-20 is a STM32F103 based 3D printer which ships with a 16KiB bootloader. Their official version of Marlin starts at 0x08004000. Signed-off-by: Simon Hawkenson <simon@hawkenson.ca>
* rp2040: implement SPILasse Dalegaard2021-07-154-0/+121
| | | | | | | This implements SPI for the rp2040 target. All output groupings of both SPI blocks are available for use. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>
* rp2040: hardware PWM supportLasse Dalegaard2021-07-094-0/+111
| | | | | | | | | | This implements hardware PWM support for the rp2040. The maximum value(100% duty) is set to 255 to match the other controllers. Cycle time is clamped automatically, and uses the full 8.4 fractional range of the rp2040 PWM block. This allows a maximum PWM frequency of 490kHz and a minimum frequency of 1915 Hz.

* rp2040: add chipid supportLasse Dalegaard2021-07-045-4/+171
| | | | | | | | | | The rp2040 doesn't have a chip ID, but the flash chip connected does. We can get this ID by asking the flash chip directly, but doing so requires disengaging the XIP layer, performing the interrogation of the flash chip, and then re-enabling the XIP layer. This gives us a 64-bit unique ID that we can use as our USB serial number. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>

* rp2040: remove unused linker optionLasse Dalegaard2021-07-041-1/+1
| | | | | | | | | In binutils 2.36 and above the -nostartfiles option is no longer ignored. -nostartfiles is actually a gcc option, and so isn't supported by ld. Earlier versions of binutils however had less error checking, and thus just ignored the option. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>

* lcd_st7920: Check CONFIG_MACH_AVR for slow mcusKevin O'Connor2021-07-042-4/+4
| | | | | | | Use CONFIG_MACH_AVR instead of CONFIG_CLOCK_FREQ to check for slow mcus. Some fast MCUs do not export a high clock frequency. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* lpc176x: Use full peripheral clock speed; fix UART interfaceKevin O'Connor2021-05-041-1/+1
| | | | | | | | | | | Commit ae89a659 caused a regression in the lpc176x UART handling. After that commit the UART clock divisor would need to be 6.25 on lpc1768 or 7.5 on lpc1769, but the code only supports whole numbers. Set the PCLKSELx registers at startup and return to using full speed peripheral clocks. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
