Benjamin Valentin	99344e8030	cpu/samd5x: make sure RIOTBOOT_LEN is 2*FLASHPAGE_SIZE ... The flashpage size on samd5x is 8k, so set RIOTBOOT_LEN accordingly.	2019-06-21 09:47:04 +02:00
Benjamin Valentin	f29ca155d8	cpu/samd5x: fix CPU init ... There were still some things wrong with samd5x CPU init which only showed up when used in conjunction with RIOTBOOT, that is cpu_init() was called twice. - gclk_connect() should block until the GCLK is ready. - DPLL should be disabled dring configuration. - make sure not to use DPLL for MCLK when re-configuring DPLL - All APBxMASK bits should be in a defined state. - always enable 1kHz oscilator output.	2019-06-20 11:29:05 +02:00
Benjamin Valentin	f375b00ff3	cpu/samd5x: add support for samd5x/same5x MCUs ... This adds supoprt for the Atmel SAMD51 & SAME54 SoC. The SAME5x/SAMD5x is a line of Cortex-M4F MCUs that share peripherals with the samd2x Cortex-M0+ and saml1x Cortex-M23 parts.	2019-06-06 16:47:11 +02:00
