samd: Move MCU-specific CFLAGS to mpconfigmcu.mk. Signed-off-by: Jim Mussared <jim.mussared@gmail.com> 2022-11-17 07:44:03 +08:00			`CFLAGS_MCU += -mtune=cortex-m4 -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard`

samd/Makefile: Set MPY_CROSS_FLAGS. Otherwise this port will be unable to freeze `@native`/`@viper` code. Signed-off-by: Jim Mussared <jim.mussared@gmail.com> 2022-11-16 11:39:59 +08:00			`MPY_CROSS_MCU_ARCH = armv7m`

samd: Rearrange the MCU-specific loader files. Such that they are easier to adapt. The maximum code size is set by: MICROPY_HW_CODESIZE=xxxK in mpconfigmcu.mk for the MCU family as default or in mpconfigboard.mk for a specific board. Setting the maximum code size allows the loader to error out if the code gets larger than the space dedicated for it.

samd/mcu: Use lf2s for SAMD51 and lfs1 for SAMD21. Using lfs1 gives a smaller code, but lfs2 has more features. 2022-07-10 17:55:56 +08:00			`MICROPY_VFS_LFS2 ?= 1`
samd/mcu/samd51: Enable FAT support for SAMD51. Tested with a SD card connected to a SAMD51 board. The SEEED WIO terminal has a SD-Card reader built-in. Also a side change to remove a few obsolete lines from Makefile. 2022-07-10 18:04:14 +08:00			`MICROPY_VFS_FAT ?= 1`
samd/mcu/samd51: Use an additional manifest.py for SAMD51 boards. Including the uasyncio scripts and the drivers for DHT, DS18x20 and onewire. The uasyncio scripts need about 8k of flash and are not included for the SAMD21 boards by default. 2022-10-27 02:17:19 +08:00			`FROZEN_MANIFEST ?= mcu/$(MCU_SERIES_LOWER)/manifest.py`

shared/runtime/gchelper: Drop cpu directive from ARM asm helpers. This drops the `.cpu` directive from the ARM gchelper_.s files. Having this directive breaks the linker when targeting older CPUs (e.g. `-mthumb -mthumb-interwork` for `-mcpu=arm7tdmi`). The actual target CPU should be determined by the compiler options. The exact CPU doesn't actually matter, but rather the supported assembly instruction set. So the files are renamed to _thumb1.s and *thumb2.s to indicate the instruction set support instead of the CPU support.
