[v4,0/9] Add support for AST1030 SoC

Message

Jamin Lin April 1, 2022, 3:46 a.m. UTC

Changes from v4:
- drop the ASPEED_SMC_FEATURE_WDT_CONTROL flag in hw/ssi/aspeed_smc.c

Changes from v3:
- remove AspeedMiniBmcMachineState state structure and
  AspeedMiniBmcMachineClass class
- remove redundant new line in hw/arm/aspeed_ast10xx.c
- drop the ASPEED_SMC_FEATURE_WDT_CONTROL flag in hw/ssi/aspeed_smc.c

Changes from v2:
- replace aspeed_ast1030.c with aspeed_ast10xx.c for minibmc SOCs family support
- Add "ast1030-evb" machine in aspeed.c and removes aspeed_minibmc.c

Changes from v1:
The patch series supports ADC, SCU, SMC, TIMER, and WDT for AST1030 SoC.
Add avocado test case for "ast1030-evb" machine.

Test steps:
1. Download image from
   https://github.com/AspeedTech-BMC/zephyr/releases/download/v00.01.04/ast1030-evb-demo.zip
2. Extract the zip file to obtain zephyr.elf
3. Run ./qemu-system-arm -M ast1030-evb -kernel $PATH/zephyr.elf -nographic
4. Test IO by Zephyr command line, commands are refer to Aspeed Zephyr
   SDK User Guide below
   https://github.com/AspeedTech-BMC/zephyr/releases/download/v00.01.04/Aspeed_Zephy_SDK_User_Guide_v00.01.04.pdf
   - ADC(channel 0):
       uart:~$ adc ADC0 resolution 10
       uart:~$ adc ADC0 calibrate 1
       uart:~$ adc ADC0 read_format 1
       uart:~$ adc ADC0 read 0
       [Result]
       read: 1416mv

   - SCU
       uart:~$ md 7e6e2040
       uart:~$ md 7e6e2080
       uart:~$ md 7e6e20d0
       uart:~$ md 7e6e2200
       uart:~$ md 7e6e2300
       uart:~$ md 7e6e25b0
       [Result]
       The register value should match the value of ast1030_a1_resets
       in aspeed_scu.c

   - Flash(fmc_cs0):
       uart:~$ flash write fmc_cs0 0 0x12345678 0x87654321 0x34127856 0x78563412
       uart:~$ flash read fmc_cs0 0 10
       [Result]
       00000000: 78 56 34 12 21 43 65 87  56 78 12 34 12 34 56 78 |xV4.!Ce. Vx.4.4Vx|

       uart:~$ flash erase fmc_cs0 0
       uart:~$ flash read fmc_cs0 0 10
       [Result]
       00000000: ff ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff |........ ........|

   - Timer(TIMER0):
       uart:~$ timer start TIMER0 -p 2000 -t 0
       TIMER0: period 20000 ms, type 0
       [Result]
       timer expired after 2 seconds

   - Watchdog(WDT1):
       uart:~$ mw 7e785008 4755
       uart:~$ mw 7e78500c 1
       [Result]
       soc reset after 22 seconds
