v0.2.2

Label v0.2.2: Changes sinces label v0.2.1 - 2025-10-31

Added

• Application images now have a header containing a magic number allowing the bootloader to detect
  their presence in flash memory.
• Added sw/components/rtcc/rtc.h which simply forwards to less easy to remember MCP794412RTC.h.

Fixed

• Fixed a typo in the Corsair assembly code generation of the register access macros.

Changed

• On FPGA, the CPU boots from flash instead of
  IMEM. Bootloader copies itself from flash to IMEM, then proceeds as before.
• Change default UART baudrate from 115200 to 1000000.
• Modified SPI Flash memory map, allocating different memory regions for bootloader
  and application software. See the Memory Map section of the documentation for details.
• Split linker variables code_start/source, data_start/source and _bss_start/source into
  icode/ecode_start/source, idata/edata_start/source, ibss/ebss_start/source and modified
  crt0.c to support them.
• Mtvec is initially at 0x11500000 after reset. Crt0's _start() function sets it to 0.

Removed

• Nothing.
