+### Artery ###
+
+This RusEFI fork of ChibiOS have some progress of porting ChibiOS to Artery
+AT32 MCU. At least some testing wa done on AT32F435 base development board.
+
+Current AT32 port mostly reuse STM32 hal drivers. Yes, AT32 is very similar
+to SMT32 including register organization. But almost all registers and bits
+inside registers have its own naming. While function of most of them are
+same as on SMT32.
+
+To keep STM32 drivers happy we decided to keep STM32 prefixes and register/
+fields naming. Don't be confised.
+
+Current AT32 status:
+- os/hal/ports/AT32/AT32F4xx/ is added with basic support
+- clock setup, IRQ mapping and startup is taken from similar STM32 chip,
+  adjusted and works. Few fixed (up to 288MHz CPU) recomended by DS PLL
+  settings defined and tested.
+- UART is working, STM32 USARTv1 driver is reused.
+- USB OTG is working (testhal/AT32/AT32F4xx/USB_CDC_IAD).
+  STM32 OTGv1 is reused.
+- ADC + DMA is working. ADCv2 and DMAv1 from STM32 are reused.
+  DMAMUX sources are defined for AT32. DMA driver a bit adjusted for AT32
+- EFL support is implemented for AT32 chips. See EFL-MFS demo in
+  testhal/STM32/multi/EFL-MFS
+- more is comming
