Scott Shawcroft	9d5742ebd1	Fix start on power up by providing Reset_Handler ourselves. ... On power up the FlexRAM banks are in an unknown config so we can't rely on the stack until after we configure FlexRAM.	2020-01-18 11:54:01 -08:00
Scott Shawcroft	7d8dac9211	Refine iMX RT memory layout and add three boards ... Introduces a way to place CircuitPython code and data into tightly coupled memory (TCM) which is accessible by the CPU in a single cycle. It also frees up room in the corresponding cache for intermittent data. Loading from external flash is slow! The data cache is also now enabled. Adds support for the iMX RT 1021 chip. Adds three new boards: * iMX RT 1020 EVK * iMX RT 1060 EVK * Teensy 4.0 Related to #2492, #2472 and #2477. Fixes #2475.	2020-01-17 17:36:08 -08:00
