Correct _etext location; clean up .ld files 1. Make _extext and _sidata coincide. Old _etext location did not include .ARM.exidx sections, which were usually absent but not always. So flash data was copied to RAM in wrong place. 2. Use decimal constants with "K" and "M" suffixes in .ld files instead of hex constants, to make them easier to read and check for accuracy. 2018-02-09 10:06:14 -05:00			`GNU linker script for SAMD21x18 (256K flash, 32K RAM)`

atmel-samd: Introduce a nvm module for non-volatile byte-level memory access. (#203) * atmel-samd: Introduce a nvm module for non-volatile byte-level memory access. This allows for persisting small configuration values even when the file system is read-only from CircuitPython. Fixes #160 * Review feedback: * Add tests. * Fix non-zero index. * Fix len() 2017-08-25 16:00:27 -04:00			`/* 256 KiB but leave 256b for internal config and 256b for user config (protected eeprom) */`
